Yes you can make the unit sound a bit quieter by sitting it on some foam or bubble wrap as I am guessing it is presently on floor screed or tiles?

I have mine boxed in and tiled (plywood with tiling on top and plastic edging). It is put together so that it can be removed for maintenance of the Saniplus unit. You can also put foam or some insulation in between the Saniflo unit and the boxing-in to deaded the sound.

It unfortunately will never be as quiet as a conventional toilet flush but that is one of the trade-offs

If this helps please leave feedback, if not let me know and I'll try and help some more

SOURCE: I have a Saniplus toilet

HI.There's no problem with the motor because it is working.The only thing here is that the relay that connects to the motor is not working.You don't need to replace your. Saniplus.There's actually 2 control menu on the side of the saniplus.These controls inside will trigger the motor to turn ON/OFF.However you said this relays does not respond to any activity once flush.This are actually composed of IC's or Integrated Circuit.If ther's an available Multitester,you can actually check it individually.Here's how to check: 1.If the unit is open and you can find the control board or circuit;Connect both ends of the Tester on that IC. 2.Make sure that the Tester's setting is in the OHMS value to chck continuity. 3.There are only 3 readings you get.First it movd to its infinite value/maximum,then IC is defective.Second if it does not give reading.Need to replaced it.Third if it gives a little but not reach maximum value,Then that IC is good. 4.Check the IC individually and replace if necessary Thank you for choosing FIXYA.

Saniplus has continual loud noise and won'y switch off

That could be due to the membrane (#15) in the schematic diagram, the membrane might be stuck in the on position or it might be warped, that's why the unit is staying on the whole time and not shutting off. The membrane is what activates the pump on and off. You will have to open up the unit and inspect it. You can also visit their website at to download the installation manual.

Saniplus toilet when toilet is flush the masorator tank leaks around the lid, nnot nice seeing \yuck streaks run down

Is not recommended to use 90 degree elbows in the discharge pipe. Is recommended to use 45 degree elbows back to back with a small piece in between or long sweeping elbows. Using hard 90 degree elbows creates resistance in the discharge pipe and does not allow the unit to pump out the waste as efficiently as it should.

I have a sanipro xr its not making the sound it use to when i use to flush and the waste doesnt go down.

The pump in the lift chamber has quit working. Check the power to it and if that's not the problem then you will have to get into where the pump is to see if the float is hung up. I know it's a nasty job but someone has to do it.

Sanipro xr is less than 6 months old been working fine but has recently become rather noisy. Sometimes goes off in the middle of the night for no reason.

Water pressure makes the unit kick on and off. Somehow water is draining back into the pump casing, check the flapper on the check valve inside the discharge elbow, it may not be closing properly or may be obstructed allowing waste water to drain back into the pump. Also check the flapper on the flush valve inside the toilet tank (water closet) the flapper may be leaking water into the bowl and from the bowl into the pump casing sitting behind. As far as making a loud noise, there could be a blockage on the drain pipe, blade or impeller. The discharge pipe may be loose, not clamped against the wall and is rattling against the wall when in use.

The SaniPlus toilet was just installed in my basement about a month ago. The water and waste will not go down. The motor continually runs, but the water level does not go down. Could it be blocked or is...

There could be a blockage somewhere in the drain pipe or inside the pump casing not allowing the waste to be pumped out. Refer to the installation manual/technical data manual and take a look at the schematic diagram for the Saniplus, It will show every component inside the pump casing, the short discharge pipe (# 7c) and long elbow (# 8) may be split open or not attached properly and waste water is just cycling inside the pump casing and not pumping out.

Sanipro continuously runs,however, not pumping waste away and waste water has filled toilet bowl. Any suggestions

There can be a blockage somewhere in the discharge pipe, the blade or impeller. Also the short discharge pipe or long elbow inside the pump casing may be split open or not attached properly and waste water is just cycling inside the pump casing. Worst case scenario could be a bad capacitor, the capacitor spins the blade and impeller, it that goes bad the unit will just hum and not pump any waste out until is replaced. You can also order parts through Saniflo if needed.
