Help please?! Do I need to add a Salamander homeboost pump to my water system? The house is 4 storeys high and I have a 2nd combi boiler (Ideal Independent C30) on the top floor running an extra sink and shower room, flow has always been pretty bad but usable - but suddenly the shower has (after 8 years) stopped producing hot water - though the bathroom sink right beside it works fine. I have had the heat exchange plate replaced and a Magnaclean system installed, but no improvement. I've been told that Thames water recently reduced pressure to my area as a whole, but they deny this.
They checked my water and tell me I have 30 litres/minute and 2.25 bar pressure at the meter immediately outside my front door - but only 10 litres/min and 1.5 bar at the first tap inside the house, 5 metres on.
Meanwhile, I had the shower cubicle replaced 6 months ago because it was leaking - can't see how this can be the problem as it worked fine to start with? (Began by thinking it was the thermostat in the shower tap that had gone, got that replaced, no difference..... then had it changed to a no-thermostat tap just in case - even worse. Seems flow to the shower is not enough to stimulate the boiler to DHW, though I can get it going (unreliably!) by starting the sink tap first.
I am now utterly confused. I've already spent around £500 on NOT solving the problem! Please can anybody on here tell me where should I concentrate? On the ground floor pipework? On the plumbing to the top floor shower cubicle? Get a pump added to the system?
(Top floor flow is only 5 litres a minute - but Salamander say their pump will only improve overall house performance from 10 litres/minute to 12, but this may be too little to change anything?)
