Q & A

Are the macerators suitable for tampons & sanitary items ? »

Items of this nature should not be disposed of through the domestic Saniflo macerator range as they are likely to cause a blockage. Our professional units Sanibest & Sanicubic are suitable for this type of product

do you have to dig up the floor ? »

As the function of the units is to pump waste and water away, it should not usually be necessary to dig up the floor to lay the discharge pipework. It is possible to run the pipework from low level to a higher level e.g. from a basement to ground floor level, or from 1st floor up into a roofspace and then join to a soil stack

What types of WC's are suitable ? »

A Saniflo macerator can only be fitted with a WC which is BS EN 33 or 37 Horizontal outlet

Are they very noisy? »

The Saniflo pumps/macerators are not in themselves very noisy and the sound of operation is generally not invasive. However, noise levels can be increased due to sympathetic resonance from stud partitions, floor voids etc.

To keep noise levels to a minimum we recommend that you sit the unit on some carpeting/rubber matting/underlay. Also please make sure that the unit is not tight up against either the WC pan or the wall.

How can I unblock my Saniflo? »

We do not recommend the use of drain unblocking products (eg containing acids etc) these will tend to damage the rubber / plastic components within the unit. We recommend that you call out a Saniflo service engineer. 

Are there any smells from the machines ? »

Correctly used and installed Saniflo units should not emit any smells. The latest models also have a carbon filter incorporated into the air inlet valve. We also recommend a regular cleaning routine to keep your Saniflo in optimum condition. Follow the procedure below: Saniflo Ltd manufacture an own branded descaler, please ask your local Saniflo supplier for details. For general cleaning purposes normal wc cleansers are also ok to use with a Saniflo product In general, normal regular cleaning may be done using any non-foaming cleaners. High foaming brands should be avoided as the agitation could cause temporary difficulties in the pumping operation. Both for descaling and general cleaning the following procedure is useful 1) Remove fuse or switch off power to unit Pour a strong dose of descalent, bleach or disinfectant (say a 1/3 or ¼ bottle) into the WC pan. 2) Flush the WC. 3) Leave to stand for 1 to 2 hours. 4) Switch power back on, allowing unit to pump out and flush WC.

Can waste be discharged into a manhole? »

A Saniflo is normally discharged into a soil and vent pipe or discharge stack. However, it is possible to connect directly into the sewer at invert level. The discharge pipe should discharge into the gulley in the direction of flow. Entry can be through the wall of the manhole. which should be sealed to ensure a watertight joint. Pipes should be suitable for use under ground and protected against frost and also against subsidance from the effect of vehicles passing above. Full details are available on Saniflo BBA certificate 87/1889 detail sheet 9. (which can be viewed on the website).

What do I do if I have a faulty unit ? »

Please contact your local Saniflo engineer by referring to our service engineer list on this website. Our service engineers will call to site to rectify problems.

What can create siphoning ? »

Where the point of discharge into the soil stack is significantly lower than the base of the unit, an anti-syphon valve / air admittance valve (capable of withstanding approx 10 psi pressure) will need to be fitted at the highest point in the piperun in order to avoid syphonage of the water seal in the unit. Alternatively use larger bore pipework for the vertical drop to "break" the syphon

How easy are they to fit ? »

A Saniflo unit is normally behind a WC suite with a horizontal outlet spigot BS EN 33 or 37. Saniflo installations require connection to an electrical power supply (5 amp unswitched fused spur) and water supply to the WC suite For the discharge, a small bore pipe (solvent weld plastic or copper 22mm or 32mm depending upon model) must discharge into a soil and vent pipe / discharge stack. It is also possible to discharge into a manhole (please refer to our website BBA certificate detail sheet 9 for underground drainage).

How should I run the inlet pipework? »

The inlets accept waste water by gravity. They do not suck in water. All pipework into the units must have a positive gravity fall (1 in 33).

What type of material should I use for the discharge pipework ? »

All discharge pipework should be either copper or rigid solvent weld plastic. Flexible pipes (e.g. those normally using metal grab ring joints) can be used. However, this pipework is ony suitable if used without joints since these tend to narrow the bore of the pipe, and also it should be supported every 1/2 metre to avoid dipping in the piperun.

Can Saniflo products discharge vertically ? »

All vertical lifts should rise as directly above the unit as possible. Any initial horizontal run from the unit prior to a vertical lift should not exceed 30cm. Only 1 lift is permitted, at the start of the run, with a 1 in 100 fall from the high point.

What is the maximum distance between WC & Saniflo unit ? »

A Saniflo macerator is designed to fit on the back of a WC. However, it is possible to install the unit behind some panelling by utilising a short extension piece which should not exceed 150mm in length. Longer extensions tend to cause an accumulation of waste at the entry to the Saniflo product.

What are the pipework sizes ? »

Saniflo, Sanitop, Saniplus, Sanichasse,Sanishower, Sanislim, Sanipack, Sanipro & Sanibest will all discharge in 22mm Sanivite, Sanispeed, Sanicom and Sanicompact must discharge in 32mm

Do I need any form of noise insulation? »

we recommend that the unit is placed on some carpetting, rubber matting, underlay or similar material to absorb vibration. Where noise is a critical factor it is recommended in addition to the above, the unit is boxed in and the void filled with insulation material e.g .rockwool. However ensure that the unit easily accesible for possible maintenance.

Grey water can NOT discharge into a rain water gulley

Do I need planning permission ? »

You do not need planning permission specifically to install a Saniflo unit. However, the installation of new toilet facilities has to comply with building regulations (eg drainage, ventilation and electrics) and so Building Control should be notified so that they can inspect the installation for compliance. For example under regualtion P, if new cabling is run this should either be installed by a qualified electrician or if not, it should be checked and certified by someone who is.

What are the important do's and dont's of installing a Sanicubic »

Discharge pipe size for Sanicubic is 50mm. It is also very important that the air vent (50mm) should be open at the top. Do not install an air admittance valve as the Sanicubic will not operate correctly if you do. Always fit isolation valves (both inlet and outlet) since servicing may be very dificult if not impossible without this. Any shower tray must be raised 250mm off the ground if used with Sanicubic. Lastly, a row of WC's (maximum 3 in a row) should be fitted with elyptical pan connectors to get a continuous fall into the Sanicubic. Sanicbic is able to pump maximum 3 WC's at the same time.

Do you provide an alarm with the machines ? »

Sanialarm is available as an accesory. Sanialarm is a small battery powered unit which can be fitted to the lid of most of the Saniflo range. In the event that the unit malfunctions and the water level therefore rises too high, the alarm will trigger and emit a high pitched sound. This is particularly useful where a Saniflo is installed behind panelling or such like. Dimensions 83mm length, 33mm height, depth 61mm * Sanialarm is NOT suitable for use with Sanicom, Sanicondens, Sanicompact & Sanicubic
