[john stracey]

How old is the membrane? Probably knackered

[john stracey]

the membrane is probably  only 8 weeks old shouldnt i get a year out of it.

is it connected up properly

[elite mike]

whats your water pressure and when you flush have you disconnected the resin first?

[john stracey]

water pressure i dont know its connected to my garden tap, no booster pump on membrane yet my next job when i get time i think its connected ok no obvious leaks visibly but internal seals might be leaking i dont know how to check this i think that is probably my next step to change these seals

add a booster pump

[Frankybadboy]

add a booster pump

i think he needs to add a pressure gauge first :

[john stracey]

how do you mean disconnect the resin i just take out the resin cannister and screw up empty vessel back on

good point.

Here is another, do you have the flush closed/open

[john stracey]

flush is in closed position i think when open water is coming out of waste only
