Looking for some advice please.
I'm ripping out our en suite to replace it, and I'm looking to replace the existing thermostatic shower with a new thermostatic shower tower. The cold feed is from the mains, and the hot will powered by a Stuart Turner Monsoon standard 3 bar single pump.
I understand that thermostatic showers need an equal hot and cold feed, so:
1) Is there a way to measure the pressure of the cold? Presumably this will vary slightly dependent on time of day, but I guess it's safe to say it's more than 3 bar?
2) Will a pressure reducing valve - such as this Honeywell one https://www.screwfix.com/p/honeywell-pressure-reducing-valve-x/7978j - do the trick of equalising the cold to the same as hot?
Another thought, the shower that I've just pulled out was also a thermostatic one, with normal feeds from the pumped hot and mains cold (i.e. no PRV). It has never worked since we moved in, as it was just cold. I always presumed it was just the cartridge that had gone, and never bothered trying to sort it as the plan was always to put a new one in. Could it have been the imbalance in pressure that stopped the old one working properly?
Thanks in advance for your suggestions.
