FAQ

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

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

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).

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).
 

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.

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.

Please refer to this section of our website

Saniflo, Sanitop, Saniplus, Sanichasse,Sanishower, Sanislim, Sanipack, Sanipro & Sanibest will all discharge in 22mm

Sanivite, Sanispeed, Sanicom and Sanicompact must discharge in 32mm
 

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.
 

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.

A Saniflo macerator can NOT be discharged into surface water drains. It must discharge into a soil / discharge stack or sewer.

Our waste water only pumps such as Sanishower, Sanivite etc can however discharge into surface water drain / open gulley in the same way as gravity discharging "grey water" currently does.

Grey water can NOT discharge into a rain water gulley

Sanipro is designed for the addition of an ensuite shower room for example in a large bedroom where an area can be given over to ensuite facilities such as a WC, shower and hand wash basin. Saniplus is designed for the addition of a complete bathroom with a WC, bath bidet, hand wash basin.

For our range of macerators you must use sanitaryware manufactured to BS EN 33 or 37 (horizontal outlet spigot)

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

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

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 an approved Saniflo service engineer. Please refer to the engineer listing on our website.

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.


 

You must not dispose of solvents such as white spirit, turpentine or other paint brish cleaners, via a Saniflo unit.

Such chemicals will damage the rubber / neoprene components in the machine and invalidate the warranty.

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:

All normal Saniflo products rely on gravity in order to function. If you were to use one of these products in a low / level access installation then it would need to be sited below the level of the shower waste, which would be extremely impractical.

The Saniflo Showermatic pump actually sucks the waste water from the shower waste and therefore can be installed above the height of the waste itself meaning it is easily accessible and far easier to install. A guide to installation can be found here.

Noise is an issue that can affect level / low access suction pumps. However, the Showermatic utilises a patented peristaltic mechanism which means that it is virtually silent in operation.

No, the Showermatic utilises a patented "auto gully" that switches on the pump the moment water is sensed in the shower waste. The pump will remain on as long as water is there.

There are several ways in which this can be achieved. In most situations a low (40mm high) shower tray would require the addition of a riser kit (adjustable feet) to be fitted in order to raise the tray sufficiently for the waste trap to be fitted above floor level. In some cases you may find this acceptable, but the addition of these feet will raise the height of the tray to over 100mm, which may defeat the the whole purpose of having a low level tray!

As part of the Sanilife range of products Saniflo have developed a tray / pump combination that is only 46mm in height with nothing below tray level and yet can still evacuate waste water easily without either having to dig the floor or raise the tray. Details of the Traymatic can be found here.

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).

Saniflo is the name of a range of pumps and macerator pumping units that enable the addition of an additional WC and other facilities such as a shower, hand wash basin or bath almost anywhere in a building even below sewer level or remote from soil stack or sewer

As you will see on the website the following products are designed to take waste from a shower;Sanislim, Sanipro,Sanipack,Sanishower, Saniplus. Which product you choose depends on where the shower is to be situated and with what other facilities - for example a WC, bidet, hand wash basin and so on. If you wish to install a shower on its own without a WC or other water and waste producers, Sanishower is the answer

Please note that only Saniplus and Sanipro are suitable for power showers.

It is possible to run the discharge from a Saniflo unit into a septic tank.

Make sure that the pipe is on a fall and suitably protected underground

Saniflo Ltd, have specially designed the sanipack to enable the complete concealment of pipework with back to wall and wall hung sanitaryware. for more details please refer to the Saniflo web site.

Saniwall is supplied as a kit comprising a macerator, dual flush cistern and steel mounting frame for a wall hung toilet (which is NOT supplied).

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. The installation video is here.

Sanicubic is part of our professional range and is a pump for discharge of waste from multiple wc's and other waste water producing appliances

The waste is pumped through 50mm pipework.
It pumps up to 11m vertically or 100m horizontally or a lesser combination of vertical and horizontal.

Inlet diameter 110mm for wc waste, 40mm for waste water.
Handles waste up to 70 degrees c for short periods.
The unit also features dual motors and 2 alarms, one unit mounted, and one remote.

For all Saniflo Ltd domestic range macerators only 1 wc per 1 unit is permissable.

For more than one please refer to the Sanicubic which can be found within our professional range on the Saniflo website.

Sanicubic is able to pump away the waste from several WC's in a commercial environment.

For example it will pump away the waste from 3 WC's simultaneously and has 4 WC inlet connections. It's twin heavy duty motors make it ideal for demanding high usage situations.

It will handle waste water from several hand basins, sinks, showers, baths, washing machines and dishwashers.

However total maximum inflow of waste should be less than 80% of the maximum possible flow rate of the Sanicubic for that installation. Please refer to "performance curve" on the Sanicubic instructions.

Sanicubic is part of the professional range which can be viewed on our website.
