Cold from Mains, Hot Pumped, what valve do I need for my basin mixer?

[tonymac]

I have a mains cold supply and a hot pumped supply that I want to use with a mixer tap in my upstairs family bathroom ( Quatra basin dual lever mixer )

The question I've got is, do I simply need a pressure reducing valve on the cold supply to bring it to the same pressure as the hot, or would an equalising valve give better results? The basin that we're replacing used pumped hot and cold, but I wanted to switch to mains cold for hygene reasons.

The hot water pressure from the pump is reasonably good (can't give figures coz I'm not at home but its strong enough to power a jacuzzi "waterfall" filler that we've got in the master bedroom ensuite).

When I had my bathroom fitted downstairs a couple of years back i'm reasonably sure the plumber fitted an equalising valve to the shower supply (it was thermostatic ev Mira shower) because again the cold feed to the shower was mains but the hot was pumped. The shower down there seems to work well though its not used very often.

Thanks for reading

Not necessary to do this for the tap. It'll work fine with mains cold and pumped hot. Just need a non-return valve on mains to be in compliance with water regulations.
