something similar happened to me... the water pressure dropped on the gauge.. i replaced the pre-filters and it fixed the problem cost's about £15-£ 20 to replace the 3 pre-filters.

does sound like the filters are blocked, when did you last change?

[rhys11]

i changed the filters 6 weeks ago

you think i should put new ones in again???

You need to hunt down the problem step by step.

Start by disconnecting the pipe coming out of the three pre-filters to see if they are the problem. If they are then one at a time remove the pre-filters from the housing, leaving the other two in, you will soon be able to isolate which is blocking the water flow. It is not unheard of for new pre-filters to block a system.

If it is not them then isolate each membrane at a time time. Finally dis-connect the pipe going into the final DI stage to see if that is the problem.

If you go through the unit systematically you will find the problem but it may take you an hour to do.

thanks Alex the water stops going into the the second small RO  what can i do now?

[rhys11]

i got a hissing sound coming out of the Flow Restrictors is that ok?

[Alex Gardiner]

So can I take it that you have water flowing through all three pre-Filters?

Then you have water flowing through the first RO membrane what about the waste? Is there water flowing through the waste restrictor? Check for a blockage in you flow restrictor. If it is blocked then they are cheap to replace.

If it is the waste restrictor that is blocked then you can 'make do' by slightly opening the waste flush valve until you get about a 50:50 waste to product ratio.
