Best way to reduce flow to taps

[FrankieF]

Hi all,
Have a problem, I have a client that has too much pressure to bathroom taps and shower, there are several types of reducer out there, can anyone recommend any in particular, the pressure is 30 litre p/m, need to reduce to 12 ish because of the type of taps. no details though, as have not seen the taps yet. They have had an "engineer" 🙄 in.......that has told them to reduce the flows......
Any help would be greatly appreciated, many thanks.😕

you could try fitting some pressure reducing valves on the pipe inlets



apologies i didn't read the question properly, there are several different types available as you know i guess it boils down to personal choice.

I've fitted wondervalves for a customer of mine - they enable you to fit flow regulators as required: www.wondervalve.co.uk

We fit the flow limiters when we do HA units.

It depends on what type of heating system they have, certain systems increase water pressure, some directly supplies all cold taps which also travels to the hot water cylinder which keeps it as a high pressure. I think you should play around with the valves to reduce the pressure, if this still doesn't work I would contact a plumber to come check it out.

go and see the system to make sure.

it is unwise to just go and do a job because a customer says 'another plumber said so.'

sounds a bit suspect to me . . .

I find that the first recourse is to try and close the stopcock somewhat, and even isolation valves to the outlets in question. Often the pressure is not so henious, and this works.

What is that crap about the 'wrong tap' - someone has not fitted a low pressure tap, onto this high pressure system have they?

Like I said, go and check it out. If you fit the pressure reducing fitting and it does not solve the problem, they will be blaming you!

Heresay is the mother of all **** ups!!

Love those "engineers" ... your post seems confusing between pressure and flow rate .. whilst a flow rate of 30 l/m is high for a LB tab you do not say what the pressure is? I imagine if 30 l/m is correct then its pretty high .. closing the stop tap slightly will certainly impede the flow but not the pressure and this will build up so that when you open the tap(s) initially there will be a surge and if there is more than one tap/appliance operating at the same time you could get too low a flow.. You need to look at the whole installation and check the flow rates and pressures at all taps .. If you can reduce the pressure as a whole without affecting the performance in the rest of the installation then OK but usually a flow restrictor at the tap is sufficient. Good luck.

Hmm!

L/m is high and as Tong says, that is flow not pressure. You can reduce flow simply by putting a washer in a 15mm coupler. All you got to do is reduce the size of the hole the water flows through. It won't reduce the pressure of course.

Thanks Guys, went to see problem.
The client told me the problem, pressure is high, and shower is emptying the h/w cyl too quickly.... so am going to try the wondervalves out, reduced the flow by turning the iso valves down, but only as a temp messure of course, as does not solve problem. But get this, the shower is part of a bristan shower mixer tap, and the "engineer" suggested we fit a bristan flow limiter on the tap, but as u know, this is not internal and fits on the spout, so wouldnt exactly fix the flow on the shower, ha, "engineer" indeed.....

closing valves does not reduce standing pressure but will reduce flow rate

If you are a member of the Chartered Institute of Plumbing and Heating Engineering you can register for free shower flow reducers . I have a box at the minute .

Hi, I ended up using the wondervalves, and they work really well, will be recommending these in the future.......thanks ocentric
