What is the difference between this product and the Kingspan Flomaster Multibloc? Are they interchangeable? Thanks.

I would say yes, however check bar pressure on existing prv , also pipe arrangement may differ slightly.

what is the rate of pressure on the " cold water balance connection" Thank you

Reduces cold mains pressure to 3 bar

Can you tell me if the cartilage ( the red and black) on the pressure relieve valve model 533002CST fits 3/4" or 22mm?

Again if you are asking questions about working on a G3 pressurised unvented hot water system you best engage a G3 Water Safe Plumber.

Will this fit warmflow in180uv, part number 3664?
