Testing water pressure for new taps

[j03]

Hi there,

I am looking aroud for bath taps and have found some that state this on their website:

"For optimum performance this range requires a high pressure water supply (1.0 bar)"

How do I test this, the cold tap comes from the mains and the hot tap comes from an immersion heater/back boiler combo.

ur mains will normally be 2-3 bar (hight pressure) and ur hot is low pressure, as its coming from ur tank in the loft.

u req balanced pressure for best results.

So what I have should be k then? 2-3 bar plus possibly up to 1 bar or will the hot water be much lower than 1 bar?

Measure the vertical distance (in metres) between base of cistern (in loft) and your bath tap outlet. Divide this by 10 - this will be the pressure in units of bars.

Unless you live in a very tall house your hot pressure will be less than 1.0 bar and therefore not adequate - the result will be poor flow from the bath mixer. If it's only a filler then may not be much of a problem, but if it actually mixes in the tap then you might find that the cold overcomes the hot to the extent that it pushes the hot back the way it came

Hmmmm..........I thought taps like this were not compliant with the water fittings regulations any longer.

If you're going to use text speak , at least do it for all of the post

ur mns wil nmly b 2-3 br (hp) nd ur ot is lp, as its comin frm ur tnk in t lft.

u req balncd pressr 4 bst reslts.

That saves all these extra characters generating carbon dioxide, and you will be helping the government reaching their emmissions targets. (A quick fart from Two-shags Prescott whilst on the job will ruin all that effort though )

I think it was the other way around - they became legal, but only if check valves are correctly fitted in the correct places

. And an excellent discovery of the apparent fact that the word censor doesn't pick up on the plural of sh*g
