improving water performance

[Hot&Cold]

we have changed the supply pipe from the old lead pipe to a 25 mdpe pipe and there was no improvement.

Was the mdpe renewed to the water main tapping ?

Hi yes. all the way to the boundary and then the water board came and connected it in the street.

I have been doing some research into accumulators and there seems to be mixed feelings on these? would one work for me in my circumstance? I could site a 500l one in the garage? or would a break tank and pump be better solution?

Did the water board charge for this work ?

 

[rikaka]

no, Scottish water covered the cost on their lead replacement scheme. I don't think much work was required in the end as the communication pipe turned out to be mdpe already, so just a new stop cock and connection of my supply pipe

anyone able to comment on the suitability of an accumulator with my pressure and flow? like I say I could site a 500l unit in the garage with the mains directly in then the output to the whole house?

or would a break tank and pump be better and pipe to avoid the kitchen tap?

As you have 3 bar static pressure, an accumulator should be suitable. Only where your static pressure is very low is the extra expense of a pump required.

I'm not a plumber or expert btw - this is just what I picked up from reading around when considering an accumulator myself. Also keep in mind that an accumulator can only be filled to roughly half of it's capacity (there's a formula available if you do a search - i posted it a few months ago). This means a 500L accumulator will only contain around 250L (usually less) water, and the rest will be air.

I'd he over the moon with 14lpm and 3 bar static from our supply.

Had to fit a Homeboost to get 12lpm!.
