Great value good quality thanks
Ordered a plug for a sink from website. Very clear information on website provided confidence that I was ordering the correct component and so it proved. Very good service.
The tap fitted perfectly and is easy to turn off and on.
This is excellent. It came with rawl plugs and screws so was easy to fit, all that was needed was 4 holes. The design is good as it is bird proof which will prevent starlings nesting in the vent shaft. Also it stops dust and leaves blowing into the shaft as there's a swing cover which blows out of the way when the fan is on.
Prompt delivery, item exactly as described. Easy to fit.
Just as described and works well

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.
