Hi All,
Brand new to this forum so please be kind! Recently taken in a project to redo my ensuite and have thoroughly enjoyed the process of learning new skills along the way however I'm coming across is bit of a stumbling block with regards to a mixer tap.
I decided to bring a main cold supply into the ensuite so that I could get a glass of drinking water from the tap without the need to go downstairs (convenience mainly!) and the hot water is on the house F&E system. The problem this caused was that there were differential water pressures.
Installed new rainfall shower and at the same time changed over shower pump to a ST shower mate 2.6 bar twin pump as the previous salamander had broken (after about 18 months)
Initially I ran a mains cold feed with PRV and check valve to the cold side of the mixer tap (it's a tap mixed within the body of the tap) and set bar to 1.0 it's recomended running pressure. Hot side I initially tried the hot water from cylinder storage using a shower power booster unit on the pipe in the bathroom just prior to the tap again with check valve. This didn't seem to work and I can only assume it's due to the shower.power booster giving around 0.4 bar (for one unit) I believe causing a differential water pressure. I could get one or other (hot or cold) but not a blend. Change of plan....
I decided to then try and use the shower pump to see if this had any positive impact. I disconnected hot feed to shower manifold and added a temp piece of pipe with PRV and check valve and fixed this to hot side of mixer tap. Again set PRV to 1.0 bar (not sure if this is advisable in long run with the pump providing 2.6 bar, not sure if it would burn pump out? Again tried it...I could get a good flow of water either hot or cold but then I turned of cold, tried to add hot it would remain cold. Having searched forums I saw that the aerators cause issues so thought I'd take that off and try and blow me down, nice blended water!
The current aerator looks to possibly be a low flow one maybe 4-5 ltd/ min so I've ordered another at 9ltr to see if less resistance might solve the issue?
Any other suggestions or thoughts on what I could do?
Thanks all in advance for your help.
