Hi All,
We want to replace vented with unvented cylinder but cannot find any decent plumber in North West London to carry out the works.
Every plumber I have called doesn't even bother to check water pressure or even flow rates. Not even British gas.
Not sure what to do now.
Currently have 2 bathrooms, one in the loft serviced via Stuart Turner pump 3bar monsoon. 1st floor bathroom serviced via the cold and hot tanks. 1st floor has obviously poor pressure and flow rates.
Mains coming in is 25mm mdpe. But unfortunately whoever installed kitchen decided to reduce it to 15mm before the stopcock.
I installed garden tap. With water pressure guage currently measuring between 3.2 and 4.2 bar static pressure. When opening 1 tap it reduces right down to 2.4bar and when also cold water tank is refilling as well it stays around 2.2bar. I believe if pipework under kitchen sink gets reworked i.e 22mm instead of 15mm that would improve the dynamic pressure. Also water flow rates are around 32 litres a minute.
I believe unvented cylinder is suitable but ideally I would prefer finding a decent plumber who would also check this before installing unvented cylinder. I don't understand why any decent plumber would not carry out basic tests before agreeing to install unvented cylinder. One plumber also mentioned not to follow the advice on any forums when I specified that dynamic pressure is more important than static pressure.
Only other option would be to have both bathrooms serviced by the shower pump.
Can anyone recommend decent plumber in North West London. If not how else could I guarantee that the pressure and flow rates are suitable for unvented cylinder.
Anyone feedback would be really helpful.
