It drains water well to a 2inch pipe. Service was very quick. Thanks.
These regulators are excellent value and offer a choice of flow rates. Having been in the shower manufacturing industry these are the best for the price I’ve seen. No need to use your old washer too. Brilliant
Quick delivery, easy to fit, met expectations
Exactly what I wanted. Made an excellent inspection / access panel in bathroom to allow access to plumbing should need arise.
Good product and excellent service from plumbing4home prompt arrival and well packaged.
Very pleased with these air vents as they fit really nicely in our soffit holes. Glad I found them as they seem a little more stronger than the other ones I had. Hope they do last in all weathers.

Frequently Asked Questions
The pressure relief valve remains closed when the water system works at desired pressure. The valve will open when system pressure reaches the set pressure (as set by valve manufacturer), allowing water to escape from the system until pressure comes back to its normal (below set) pressure.
All our pressure relief valves are non-adjustable and have manufacturer pressure set in place. We however have wide range of PRV valve with many different pressure settings in our offer, so you can match the pressure to meet your requirements.
