Question about Saniflo Sanibest Grinder Pump Only 013
Saniflow plus will not work on shower and basin side have removed the pipe into the saniflow and its all clear reconnected the pipe ran some water through the pipe but will not work.
Thanks for the clarification - This rules out power supply to the unit, motors/pump and points more towards why the water would be pumped from the WC flush and not the basins ...
1. The Saniflo range of macerators have a pressure switch that engages when the water pressure inside the unit activates a microswitch that is encased in a waterproof container. It is possible that the water pressure from the shower and basins is not great enough to activate the internal switch.
So, I would propose two checks
a) If the unit previously worked for the shower and basins something has changed and it is most likely to be gunk inside the unit causing the switch to be less sensitive and only activate on the high pressure that the WC would provide. The fix would be to open up the unit and clean it - please let me know if you need info on how to do this
b) If this is a new install and the shower and basins never worked, you should check the fall in the pipework into the Saniflo is sufficient (should be 1 in 70 from memory - full install instructions are available from the Saniflo website)
c) It could be that if the unit has been in for a long time with a large number of operations that the microswitch is starting to fail and is not as sensitive as it once was (quite unlikely) - but always a possibility!
Replacement microswitches are freely available online and you should also be able to get the exact match spares from Saniflo
If this helps please leave feedback - if not please let me know and I'll try and help some more!
Good Luck :)
