If anything goes wrong with the unit it usually happens in the pressure chamber, the motors are very durable, any part in there can be replaced. Im thinking the capacitor might have seized up and will probably need to be replaced.

Could be an obstruction in the blade, impeller or the discharge line. Also the starting capacitor may have gone bad and is not keeping up with the head pressure, it may need to be replaced. But i would suggest inspectin the unit first for any obstructions.

IS YOUR PUMP WORKING

The internal motor capacitor has failed - most common problem with these unitsI have posted repair instructions here:Saniplus repair instructionsIt is a PDF

Of course. Bleach will not harm the toilet or plumbing and will help alleviate odor issues if they exist.

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.

Most Saniflo products comes with a 1/2" opening on top of the pump casing, which the opening is for European installations only (this is also used in Europe) in the US the 1/2" opening must be kept plugged, if left open, odor will come out of the hole there. But make sure that you cap the 1/2" opening and vent the unit using the 1 1/2" vent connection on top. Make sure is vented to the open air, as air must flow in and out at all times.

Is the unit plugged in the GFI? Could also be a problem with the pressure chamber or float switch that activates the pump on and off. I suggest that you contact Saniflo Tech support about this issue.

If you have a Saniplus model then the vent connection is on the top right side of the pump casing if you are facing the toilet with pump sitting behind. The vent pipe needs to be minimum 1 1/2" and must be vented to the open air so air can flow in and out at all times. To the left side of the vent connection is the discharge pipe which should be a 3/4" or 1" discharge pipe. You can try disconnecting the vent pipe and run it with the vent pipe open, also you can disconnect the discharge pipe and put a bucket at the end of the discharge elbow and flush the toilet into the bucket, it will free flow into the bucket and there are no restrictions. That way you can tell if the problem is the pump or the installation set up.

Rick: It sounds like the grinder is bound up in the unit. Hair can get wrapped around the grinder blade and freeze it up. Take the unit out and remove the grinder blade and see if that fixes the problem. New grinder blades are available from Saniflow USA.

Jim:The check valve should be the fitting coming right out of the unit. It is a one way valve that only allows the unit to push water out. The check valve prevents water from coming back down into the unit. What issues are you having?Martin Rizzo ([email protected])

hi,

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.
Also you have to check the micro switch used for the floting control. Have attched a link check page 9 you can see the schematic diagram.
