## Questions & Answers

**Q: What is the difference between this product and the Kingspan Flomaster Multibloc? Are they interchangeable? Thanks.**
A: I would say yes, however check bar pressure on existing prv , also pipe arrangement may differ slightly.

**Q: what is the rate of pressure on the " cold water balance connection" Thank you**
A: Reduces cold mains pressure to 3 bar

**Q: Can you tell me if the cartilage ( the red and black) on the pressure relieve valve model  533002CST fits  3/4" or 22mm?**
A: Again if you are asking questions about working on a G3 pressurised unvented hot water system you best engage a G3 Water Safe Plumber.

After checking with our Technical Team they believe that this will fit the warmflow in180uv.

### ⭐⭐⭐⭐⭐ Perfect Replacement
*by D***Z on 3 January 2026*

My Pressure Release Valve had started leaking in to the tun-dish on my old one and required a replacement valve. Just as cheap and easier to get on Amazon, so purchased and it arrived next day, fitted, and worked perfectly since then.
