from 1092 reviewsThese 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.

Needed replacement aerator and this was the perfect fit.
Just what I needed excellent service will use them again
Good quality, and perfect size for high flow system for water softener.
Repeat of regular order, as per usual order processed and dispatched promptly and quality product, many thanks!
This solid brass tap extension is excellent. You'll need to tape the threads to ensure your tap to end up in the correct position, as you'd expect.
Great quality and price
Had to take a millimeter off the internal diameter so it would fit over the nut of a Tristan shower compression joint, this was nothing to do with the product , it's cos the Tristan shower covers where to small in diameter to cover the pipe holes
I ordered similar parts in quick succession and on both occasions they handled my order swiftly which was pleasing.

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.
