Minimum Water Pressure / Flow Rate

[Dan Masey]

Iv been called back to the same property several times in the last 6 for the same problem. The tenant is complaining her water pressure is very poor. So this time i decided to do a proper test and found a Pressure of just under 2bar and a flow rate on the kitchen cold tap of 15Litres per minute. The main problem is when 2 or more appliances are trying to run at the same time. ie shower / washing machine.

Anyone know the minimum legal requirements?

0.9 bar and sweet FA flow. 15l/min is well above the legal mimimum.

You will find this is the same in all houses even if there's 20l per min, when you open 2 taps it will give roughly 10l to each tap.

basic maths isn't it mate. try telling a stroppy tenant that.

 

[Reltub]

Lol tell me about it! Nothing you can do just tell them that's how it is and you won't be re visiting.

 

[aqualogic7]

tell them to call water company let them tell them they will not get any more pressure or flow

 

[Alpha man]

Or quote them for a new incoming water main, LOL, they may not be quite so keen on calling you back then!

I would try and sell them the grunfos mains water booster pump - its wras approved and on here somewhere............. centralheatking

Isn't that restricted to 12 lpm though?

 

[AWheating]

yes that pump is upto 12lpm, anything above must have a break tank.

as mike said its normally 0.9bar and a very low flow and thats at the stop tap at the roadside i believe.

is it a combi boiler fitted?

what you could consider doing its fitting flow restrictors at the outlets to help even the flow rates maybe. they would be better of with a open vented hot water system i guess if its such an issue for them.
