Device to reduce the cold water pressure to a shower?
 

Hi.

Putting a new bathroom in. Nice corner bath, Mira Exel shower. Gonna
feel very medetterenian! :)

Nice shower the Exel, but I have to turn the temprature right up to
the stop to get the really hot water. The problem seems to be that
the cold water is giving far more flow / pressure than the hot.
(Supply is a WB greenstar combi putting out 14l/min DHW. )

I've tried just closing the isolator for the shower a bit, but it
makes such a noise as the water goes through that it's not an option.
Is there a device that is designed to QUIETLY reduce water pressure in
a pipe?

Mucho thanks.

Isn't the mixer valve in the shower adjustable, to allow the hot inlet to be
open more than the cold in the central position?

If not, you could perhaps use a pressure reducer (or more strictly, a flow
reducer) of the type supplied with Torbeck cistern valves. This is a plastic
slug with a very course thread on the outside, with provides blockage and
forces the water to flow in a spiral. One of these inside a 15mm supply pipe
*may* do the trick.

There is such a thing available as we have one on our shower. Unfortunately
I inherited the shower, and therefore the device, from the previous owner of
the house so I don't know anything about it. I think the installation
instructions may be in the pile of documents she left me so I will look
tonight if I remember and find out the make/model/correct name is.

Err, isn't that the idea, what would be the point of having really hot
water at 3 say?

Hmmm, I have an excel running off a combi. The difference in flow rates
should not be an issue - that's one point of having a thermostatic
shower. Certainly with a combi you will get a difference in flow rates
with hot and cold for the obvious reason.

Does the manual say anything? I'm trying to remember if there is any
adjustment in the unit. You could ring customer services about it. I did
over something else, and they were helpful.

I do have a problem with too high pressure in the cold supply to mine
however, but the symptoms here are whistling /screeching noise from the
valve. I was able to relieve this by turning on a cold tap in the
bathroom, but the longer term solution was to fit a pressure reducing
valve in the cold supply to the shower. The same may be want you want as
well. But I think the shower should be dealing with this.

Sorry this is a bit late Mike, have a look at this, 35quid + vat + post, and it
may sing like your other solution, but it claims to do exactly what you're
after: Water pressure qualising valve, item 2 on page:
