We needed a new mixer valve for our system as the old unit was on its way out, Looked around online and found a replacement part on the site for a really good price. Part was ordered and arrived in the alloted time
Great service and product will use again

Searched local sellers & not in stock & would be at least 2/3 days for arrival at there retail shops & the part was £25 more. This part from Plumbworld was in stock & available for next day delivery for extra £4. Sales lady was very helpful all-sorted in a few minutes, email received from plumbworld asap once paid & email for courier for next day delivery. Part arrived with new gaskets & screws & a 5 min fit. Shower worked perfect & no more leaks & the control knob was easier to rotate than the old part. So a happy wife, which in turn makes me a happy man, happy days. Will be using them again very shortly for my tap insert replacements. Thanks to all.

This item was bought to replace an existing item and was an exact match just as wanted, at the best price I could find anywhere beating Ebay and Amazon and other retailers. Brilliant with free and fast delivery too. Superb service as well. Thank you.

These are easy to get fitted. The main problem with them is the screws rust heavily over time. I had to dissect the old one from the corners in order to get it out. But they do last more than 10 years so they are of respectable quality.

Super fast delivery and super easy to install, 4 screws holding the temperature control knob, then 4 torque screws holding the cartridge in, replace the o ring at the rear then install the new cartridge, so simple and works a treat.

This item was available from a number of suppliers. However Plumbworld had the best price, especially taking into account free delivery. New Cartridge works well and resolved issues we had.

Considerably cheaper than buying the identical item direct from Aqualisa. Easy to place the order and item arrived promptly.
Couldn't ask for more - very pleased.
