from 1140 reviewsEasy transaction for a couple of replacement parts. Quick service too.
Most useful items when connecting thin wires to connector blocks. Service is great as I received the items in double quick time
Very pleased, great job, thank you
Quick delivery and a product that works.
Wanted a grill vent for kitchen extractor but didn’t want the wind blowing back through. This vent has a backdraft flap plus it is angled downwards and works brilliantly.
Excellent item-no drips. And quick posting. Happy
Bath plug chain, works as expected.
Website easy to navigate and an excellent service. Toilet seat fittings did the job easily and quickly in under ten minutes. Everybody happy now the job’s done.
When the council decided to dig up our road, we were without water for some time. The water pressure had built up, blowing our tap. An expensive tap replacement was feared but this has done the trick to make my tap last for a while longer. Thank you!
Nifty little device that helps save us some money.
First order mislaid by Post Office. Problem dealt with immediately and a replacement was sent and received promptly. Product was exactly as ordered. Good value for money.
Was very useful, a bit of a game fitting it, maybe a hinged design ?, needed 3 hands, but ultimately Stopped the leak 👌🏻
I had been scouring the plumbing and DIY shops for water tap aerator and in in not a standard size for months. The internet sites including the major online sellers didn't come up with the exact requirement. Plumbing4 Home should have been on top of the " search' results as when I did get to it found it very widely and fully stocked. On top of that this Company provided a seamless and swift delivery of my £7 part! Will be back to them for any future requirements
I have spent quite a long time to find the size of kitchen strainer so was delighted to find the right one and the right fit. Very happy with my purchase which came very quickly. Thanks Team
Well made vent. Better than other types I’ve tried

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.
