hi guys wondering if any of you guys could shed sum light on this problem 4 me just fitted a en suite in my celler using a saniplus which has a 5mtr vertical limit i av a wc. a basin. and a shower connected to it problem is wen i run the shower and flushed the toilet to check saniplus it seems to fire up like the motors running but it isnt pumping the water away i av a fall from the shower and basin to the unit but wen testing it water backed up into the shower tray any ideas guys here are sum facts as i dont want to waste anyones time cheers . fall from shower and basin to unit ok ? all pipework seems watertight cant find no leaks ? vertical rise under 5 mtrs ? all bends long radius ? hope this makes sense and hope someone as an idea as its drove me mad lol thanx

There'll be a non-return valve in the macerator is this in the right way is there on fitted
?
does any waste water reach the top of the waste pipe ?

Does the installation instructions not advise fitting non-return valves to the bath and basin waste ? i would be adding them

If it's been fitted according to instructions, I would get the manufacturers out.

thanx 4 reply htg engineer the instructions dont mention fitting any non return valves but do you reccomend i shud fit one also i have combined the shower and basin waste together that way i can box all the waste pipes in together makes a neater job cud that cause the saniplus not 2 work ? and how much are non return valves and were is the best place to purchase one thanxs again 4 your help bazza

I would fit one, it's not going to affect the operation of the macerator all it will do it is if there's ever a problem with the saniflow it'll stop waste from the toilet backing up to the bath or basin, I would imagine the saniflow will have them built in - check the instructions again.

Is the pump going or just making a noise ? you could disconnect the pipe from the saniflow and run clean water through it - see if it's pumping.
