Can hair block the PLANCOFIX floor drainage pump?
Not in principle. As with every ‘normal’ drain it is also important to clean the collection chamber regularly. No deposits are to be expected in the hydraulic sector because of the flow.
Is it also permissible to use the floor drainage pump as a lifting station, e.g. for a bath or washbasin?
No, the Plancofix was only designed as a pumping floor drain for showers. It is not approved as a lifting station in accordance with DIN EN 12050. It should also be taken into account that, for example, the quantity of water introduced by draining of a bath would be too great.
Are 230 volts allowed in the shower area (protection zone 0)?
Protection zone 0 only begins at the surface of the floor and Plancofix therefore has the corresponding VDE approval. Final electrical safety must be realised on site via the ground fault circuit interrupter.
Is it possible to exchange the Plancofix floor drainage pump later on?
The Plancofix is constructed in such a way that all its components can be exchanged separately if necessary. This relates to the motor, the hydraulic system and all other elements. The only process that requires substantial effort is the removal of the tank. But this should remain in the floor for many years after installation.
Does the power supply line also need to be exchanged if the Plancofix pump is exchanged?
No, the power connection can be separated from the motor compartment. Please note: the connection for the cable conduit is in place and should be used. This would even allow exchange of the power supply line but this is never normally required!
Is it possible to use the Plancofix floor drainage pump to transport condensate?
No, because the metallic materials such as the switching shaft are not durable enough. This application is described clearly in the operating instructions, which must be observed!
Why does the transfer point into the downpipe have to be 25 cm above the Plancofix?
It must always be ensured that there is sufficient water pressure on the backflow flapp installed in the Plancofix floor drainage pump to ensure proper closing of the valve and minimise noise. In addition, the pressure pipe must be extended from the high point to avoid a so-called suction lift.
What’s the difference between “sewage” and “effluent”?
Basically, we’re talking about the size of the solids in the liquid. Effluent water can contain solids up to 5 cm in size. This is normally considered to be water containing soap, laundry discharge, water from sinks, etc. Water with larger solids is called sewage water.
Can I pump other liquids with this pump?
Our pumps are designed to pump sewage water. We have not tested the pumps with other liquids and cannot say whether they will be chemically compatible with what you need to pump. Never pump anything flammable with any of our pumps!
What does the addition NIRO with the U3 K submersible pump mean and does it still exist?
In the past, the addition NIRO always stood for "rustproof" motor shells for our U3 K submersible pumps. This addition was chosen in 1978 for the revised U3 K to highlight this new product feature. Over the years, the design of the pump has always been adapted and a non-rusting motor shell has been established as a normal product feature. For this reason, the addition was dropped more than 10 years ago. Instead of the U3 K Niro, please order a U3 K (pump without automatic switching) or U3 KS (pump with automatic switching).
The product designation U3K+KS/2 on the nameplate of the U3 K submersible pump is confusing?
Please note that several variants of the U3 submersible pump with product designation are named on the nameplate. The U3 K submersible pump without float switch. The U3 KS submersible pump with float switch. The number behind the slash is the design code number, and helps us to select the right spare parts for your product.
Do I need a hot water pump or hot water tank for my domestic washing machine?
No, not as a rule. The detergent solution from domestic washing machines is cooled before being pumped out and then additionally mixes with the cooler residual water in the pump sump or collecting tank. This also results in our note in the operating instructions that the pumped medium may have a maximum temperature of 35° C to enable continuous operation of the pump.
How much dirt & debris can a submersible pump handle?
Most submersible pumps are designed to pump clear, clean water. Debris can block off the intake causing the pump to be starved for water. If it gets to the inside of the pump, the debris can damage the impeller, shaft seal, and other internal parts. Depending on the size of solids the pump selection must be done.
What size and how much performance should my submersible pump have?
Selecting the right size and power of the ideal submersible pump results from the height and the amount of water that should be pumped. For each pump, the performance can be read from the performance curve.
Is installing a sump pump difficult?
Installing a sump pump is typically easily done in a matter of minutes. The only tools you’ll need are channel locks, screwdriver, and, in rigid installations, a hacksaw. Complete easy-to-read installation instructions are included with each pump. We always recommend a new check valve when replacing your sump pump. A lot of videos and animations you can find on our YouTube channel.
Do I always need to install a check valve with my sump pump?
The short answer here is “Usually- yes.” A check valve gets installed in the discharge pipe of your sump pump. When the pump runs, the water is forced out through the valve. When the pump shuts off, gravity wants the water in the discharge pipe to fall back into the sump pit. The check valve prevents that from happening. This prevents the pump from having to re-pump water that it has already pumped out. In the long run, this should extend the life of the pump and save you electricity.
Do I need a backup sump pump? Or a second pump?
The use of a so-called dual system is mandatory necessarily where the sewage flow must not be interrupted (e.g in restaurants). In contrast, having a backup or secondary pump is like having insurance on your car or home. It´s only needed if the installed pump fails. The purchase of a replacement pump depends on the local conditions.
Is it OK for my pump to pump out my laundry water discharge?
Yes, all pumps are suitable to pump laundry water.
How big should my sump pit be?
You want to have a sump pit large enough to use a pump with a tethered float switch. That allows a reasonable amount of water to accumulate before the pump has to run. The longer “off” time between pump cycles allows the pump to cool off more completely between pumping cycles. The specific minimum sizes of the required sump pit please refer to the respective data sheet.
Is there a fuse inside this pump?
Yes, almost all submersible pumps on the market have a thermal fuse. This triggers when the motor gets too hot due to dry running or blocking and switches on again automatically after cooling down. The quality of this thermostat is therefore decisive for the durability of the pump. All our products for domestic appliances have a VDE mark and must meet the requirements of the household appliance standard for permanently installed, permanently connected products. For example, a U3K submersible pump must still function when it has been blocked continuously for 18 days in the switched-on state.
Can I use an extension cord with sewage, sump or effluent pumps?
We very strongly recommend that you do NOT use an extension cord.
Do you have pumps with longer cords? My outlet is pretty far from where the pump will be.
Some pumps can be ordered with a longer cord. We also sell longer power cords for some of our pumps. If you need further information please call our sales representatives or our colleagues in the sales service.
Can I use a sump pump for my waterfall, koi pond, or garden pond aeration?
No, for these requirements sump pumps are not suitable.
Can I use a sprayer handle that shuts off flow from the pump?
No. Pumps are designed to move water. If you block the discharge of a pump (such as a sprayer handle would do) then the pump will be automatically switched off by the thermostat.
When you say “solids” what do you mean?
“Solids” do not mean things like bolts and stones. We are talking about things that normally get passed through drains or flushed down a toilet. Most sewage pumps have a thermoplastic impeller that could be damaged by very hard items.
Is a "solids handling" pump the same as a "grinder" pump?
No. Technically speaking, a “grinder” pump has an impeller that is made like blades. It can cut up, or grind up the sewage being passed through it. Regular sewage pumps do not do that. “Solids handling” pumps simply pass the solids through mostly intact, without cutting or grinding.
Can the pump handle feminine products that have been flushed down a toilet?
No. Feminine products should not be flushed when a sewage pump has to handle that. Sewage pumps can have problems passing those items and could become jammed.
How long should my sewage pump last?
This is almost impossible to answer. It’s much like asking how long your car will last. It simply depends too much on how often the pump has to run. If you have a small sump, and you have several people in the home, the pump will have to run a lot more than someone with a larger sump. Depending on the number of accrued hours of operation and the care and maintenance, the durability of the pump will be.
Can I use this sewage pump to pump water in my waterfall, pond, or water feature?
No. Sewage pumps are not suitable for these applications.
May I also position a WCfix further away and feed the waste water to the unit through a longer inlet?
No, you shouldn't do that. The WCfix 260 / WCfix plus is a sewage lifting unit for limited use. The installation and application possibilities are regulated in DIN EN 12050-3. Accordingly, the toilet must be connected directly to the lifting unit.
The longer the feed line, the more air is introduced into the WCfix. This air may only be able to escape from the container ventilation very slowly. The accumulation pressure in the tank is too high, which causes the pressure switch to switch on earlier. The result is that the pump then starts too early. Since the WCfix switches off time-dependently, it is possible that the pump switches off if there are still solids in the tank. Over time, this leads to the lifting unit clogging up and eventually failing.
Experience has shown that this effect can be avoided by ventilating the inlet pipe. But we cannot guarantee that.
Why may the compli sewage lifting unit not be installed outside in a shaft?
The installation of compli lifting units in shafts outside the building is hardly feasible according to DIN standards.
The following requirements of DIN EN 12056-4 are generally not to be fulfilled: The working area of at least 60 cm next to and above all parts of the system to be operated and maintained. Maintenance and repairs of a container lifting unit installed in a shaft are hardly feasible in this environment. In addition, the following points can hardly be implemented: The installation of a gate valve on the inlet side. Leading the pressure line with the bottom of the backwater loop (frost-free!) over the so-called backwater level. Installing the controller in a dry and well-ventilated room. The ventilation duct is routed over the roof.
Finally, the system must also fit through the shaft opening. Therefore, submersible pumps or pumping stations are usually used for shafts outside the house.
May I discharge condensate from condensing boilers and waste water from softeners into a compli sewage lifting unit?
No, our sewage lifting units are resistant to wastewater up to a salt content of 1% and within the pH range of 6 - 12. The regeneration water of softeners is usually around 10%, the condensate from gas condensing boilers is in the pH range of 2.8 - 4.9.
For this application we therefore recommend our drainage lifting station Hebefix extra in addition to the Compli system. This is resistant up to a salt content of max. 10 %. This is usually sufficient for "small to medium" softening plants. If in doubt, please contact the manufacturer of the softener.
Why are the sewage lifting units so heavy?
The pump components of the Compli lifting units 400 and 1000 are based on the heavy quality of our submersible sewage pumps made of cast iron. The housings have thick walls and thus a high mass. This mass inertia also reduces vibrations and excessive noise, which means that the systems can hardly be heard during operation. Another advantage is the heavy pump housing trough, the interface between the collecting tank and the pump. This absorbs dynamic forces from the pumping process and enables relaxed maintenance work over many years. Sewage lifting units made of robust technology are only installed once in the cellar shaft and remain there for decades.
What kind of hose or pipe is best to use for discharge from this pump?
It is best to use a hose or pipe that is the same size as (or larger than) the pump’s actual discharge. Using a reducer, smaller hose, or smaller pipe, will reduce the output of the pump. If reduced too much, the pump can even be damaged. If the pump came from the factory with a garden hose adapter, then it is designed to be used with a garden hose. Keep in mind that garden hoses come in different diameters and lengths. Use a garden hose that is as fat as possible, and as short as possible. This will give the pump the ability to perform as well as it can.
Can I use a smaller discharge pipe than recommended?
Never use a smaller diameter pipe than the size of the pump’s discharge. You may even have to use larger diameter pipe if you have to push a long distance. Be careful with this though, because if a pipe of too large a diameter is used, the flow rate of the discharge can be too slow. This can cause the solids to settle out and lay in the pipe. Over time, the sludge that builds up will cause blockages in the pipe. The minimum flow rate of sewage and other liquids containing solids is 0,7 meter per second. If you are designing a sewage run for your home, please contact your plumber.
Can I use a much larger discharge pipe than recommended without problems?
If a pipe of too large a diameter is used, the flow rate of the discharge can be too slow. This can cause the solids to settle out and lay in the pipe. Over time, the sludge that builds up will cause blockages in the pipe. The minimum flow rate of sewage and other liquids containing solids is 0,7 meter per second. If you are designing a sewage run for your home, please contact your plumber.
What will happen if my outside discharge pipe freezes or is otherwise blocked?
If your discharge pipe freezes, or in any way becomes plugged, there is no place for the water to go when the pump runs. The pump is still going to run when the float switch is raised. If it cannot discharge the water through the regular discharge hose or pipe, it’s going to continue to run and run. This will eventually cause the pump to overheat and shut off due to its internal thermal overload protection. If the problem is not caught soon enough, it would be possible for your basement to flood. Due to this fact a separate alarm system is useful.
Does the check valve need to be installed horizontally instead of vertically?
No, we (as well as others) recommend you install the check valve in a vertical position (up-and-down), so that the integrated flap is inserted horizontally. When the pump shuts off, the check valve will be closed by the action of the water colomn above.
Where can I find the model number and date of manufacture on my pump?
On all sump, sewage, and utility pumps we attach a label that has the pump number, the CE sign and some technical data of the product on it. The first two digits of the pump number indicate the year of production.
Where can I get repair parts for my pump, or accessories I might need?
Repair parts can be ordered directly through us by calling +49 (0) 1805/188887 or writing an email to firstname.lastname@example.org.
I think I have a warranty issue with my pump. How do I proceed?
In deviation from the statutory regulations, the length of our warranty period for private as well as commercial customers is always 2 years!
