20 Most Recent Saniflo SaniPlus-Round SaniPlus Macerator Toilet with Round Bowl - Page 6 Questions & Answers

you cant it is set by the bends in side the bowl all toilets are this way it is a trap design that keeps fumes from septic from comming in

under the backflow valve there is a rubber connection piece check for cracks mine did same there was a crack in it letting water blow right back in tank mine was lot louder than normal also i replaced and it went back to working fine

Use some Plastic or Steel Putty for fixing it ( ex . Weicon / Belezona / Mseal / Araldate / Devcon etc)

The Saniplus has a pressure chamber and at the bottom is a rubber membrane which acts as a float switch. Water pressure pushes up on the membrane, the unit turns on, pumps out the waste and as the pressure is released, the membrane goes back down and shuts off. So the problem might be a warped membrane, something stuck at the bottom of the membrane or the microswitch may be stuck on the on position. You will have to open the unit and remove the motor and pressure chamber to inspect it. Also the water level on the toilet is meant to be very low, Saniflo uses a rear discharge toilet, not a bottom discharge (standard toilet). Unfortunately the water level cannot be adjusted on Saniflo toilets.

The following are the possible problems and solutions:

1. The tank flapper (Flush Valve) leaking allowing water into bowl. Make sure flapper is fully seated. If flapper is fully seated and still is leaking replace flapper.
2. Faulty Non-Return Check Valve, water leaking back into Macerator. Clean and Inspect check valve replace if after clean water still flows back into Macerator.
3. Check micro switch, the micro switch turns on pump when the water level reaches to a determined level. Location of switch is in the pressure chamber. Check to see if switch is sticking.Note: For safety Macerator should never be operated with lid open

The plumbing under the slab floor has been roughed in wrong and without breaking up the floor and replaceing you cann adjust the floats in the pump pitr to come on earlier to avoid pit filling up as fast causing the waste to back up in the tub/ shower area.

This seems like a problem with your cistern and not your macerator - I have a similar set up and if your push button is stuck you need to check the mechanism in the cistern - also you should have an overflow that drains into your loo within the cistern so you should check this for blockages as well.

Any brand approved for septic should work well in the saniflow system, but the key is to use as little as reasonably possible and flush as you go. Big wads of any type will compromise the system.

Make sure there is water in the rear tank. Check that the wax seal between toilet and floor is not rotted out.

The lid seal has an opening all around the seal. Make sure the opening faces up inside the lid, there is a groove inside the lid where the lid seal sits in place. Once is placed correctly on the lid, lubricate the lid seal with soapy water and then place on top of the pump casing and just put pressure on the side tabs so it snaps in place. Note that sometimes is required to use a C-Clamp to put the lid back on.

Hi Neil,
The pump is activated by a pressure switch inside the unit and would not normally make any noise, so probably can rule that one out!

From the manual on the saniflo it would suggest either a foreign object in the unit, a defective motor or control unit. It may be that you are unlucky and have a loose macerator blade that needs to be tightened (and loctite applied).

I would double check that the clunking is definitely coming from inside the unit and not a pipe or something else moving (the water pushing the 90 degree rubber discharge tends to move and can create movement around it). When you are sure, it will be the not so nice job of opening up the unit:

FIRST .. RUN THROUGH CLEAN WATER (will make sense later!)

- *** DISCONNECT FROM THE MAINS SUPPLY ***
- Empty the Cistern, bowl and disconnect the inlet pipes to the WC
- remove the WC and cistern
- being very careful, disconnect the outlet (some have non return valves, some don't, so you may get some sludge coming back down the pipe). Hopefully none if you pushed enough clean water through initially

get unit out and wear rubber gloves to protect your hands from getting germs in cuts etc. Normally need a star driver and flat blade screwdriver

If it is the macerator blade it should be clear that it is loose and could be tightened up. It could be play in the motor which unfortunately would mean a new unit - to test, gently pull up on macerator blade and feel for movement vertically.

also check for any foreign objects etc.

While it is out you may as well clean it out - I normally do this outside by putting warm bleached water into the unit for around 30mins, swishing it about and then emptying down a drain (cover up the mains cables in a plastic food bag first!). I also sometimes use a hose pipe to really get into all of the nooks.

Good luck with the fix, if this helps pls leave feedback, if not let me know and I'll try and help some more

Cheers

hi keith

Bloues hear.
the water level in the boul is standerd to the manefactuer. the plumber cant help for that. if u put a level on ur toilet and iets level there is noting u can do about it.. the water that keeps on runing is ur seal rubber, its located at the bottem of ur flush meganusum. step 1.... tack off sistern aka pump. then step 2 ... unscrew your flush meganusem, will be the 1 in the middel of sistern. step 3 ... after unsrewing it u wil see there is a rubber. if the rubber looks fine then u must ajust ur flush meganisems arm or lubricate it. bt if rubber is misformed or teared ... u must go to a plumbing shop with the rubber. they will give u new 1 for cheap. and u can just reaplace it and esembel the sistern again

Hi,
No!!! seal the hole with silicone caulk... it will still work just fine!!!

This could be a problem with the capacitor which drives the blade and impeller. If it goes bad it will pump water only but when solids are flushed, it will jam the blade and cause it not to spin. You may have to replace the capacitor/condenser.

You could try plunging the toilet or using a toilet auger to loosen the object and pull it back out. If that does not work, then you will need to pull the toilet and back-flush to push the object out of the drain and back into the bowl so you can remove it.

Could be something stuck on the blade or the impeller. You can unplug the unit from the GFI, remove all the piping attached, remove the unit completely out the back of the toilet, pry open the lid with a flat head screwdriver, remove 2 screws in front and 1 at the back of the pump casing, then you will be able to remove the motor and pressure chamber out of the pump casing. Therefore you can put it on a work bench and inspect the blade and impeller for obstructions.

If the pump is tripping the GFI then could be a broken pressure chamber, which is were all the electrical components are and if it senses water it will trip the GFI. Solution will be to replace pressure chamber complete.

If the pump is turning on by itself then water could be draining back into the pump. Either the flapper inside the toilet tank is leaking water or the check valve on the discharge elbow is not closing all the way. Solution will be to inspect flapper on flush valve (inside toilet tank) or may need to be replaced. Also the flapper on the check valve must be inspected for obstructions of may need to be replaced.

One of my customers had a similar problem. The solution was that the shower base needed to be elevated. From top of shower drain to floor level should be roughly 8" to 9"

there might be an obstical around the blade that prevents it from working. try to c or maby the line is blocked backing up the water dos the oder toilet water level drop?? if so then prob the blade that is stuck

HI is the shower and toilet on the second floor???

If so iets your 110 waste pyp that is blocked and u must try and look for an inspectoin eye to plunge it. dont throw draincleaner down your pyp becose you also have a leak. the drain cleaner can make the leak worse. if u dont get an inspection eye call a plumber. becose u will probebly need 1 to fix the 110 pyp where ever the leak may be.
