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.
Parts arrived quickly and good quality.
Was exactly as described, good quality item, came with suitable adapter for male/female spouts, so was able to fit it easily. Arrived quickly. Reduces water flow and stops splashing of water so the sink edges are now dry.
Came when promised.
Fits sink perfectly
After visiting numerous large DIY and bathroom stores and either not having a suitable items in stock or being told that I would need to know the exact item number in order to purchase a replacement, I went to Plumbing4 home and a very knowledgeable man had a look at my shower screen seal, went out into the stock room and lo and behold came back with exactly what I needed, in fact I purchased two so I dont have to worry about sourcing another any time soon. Will definitely come here again if I need any further plumbing supplies, thank you again :)
