Rated 5 out of 5 by from good kit but faulty I'm writing this review to make people aware of a fault I had with a new grey cartridge. I had a weeping leak on my aqualisa 609 concealed shower. It was leaking from the front and actually tracking back into the cavity and making the bedroom floor on the backside wet. I initially tried fitting a new o ring ( cheapest option, but didn't work) O.K so ordered a grey cartridge . It arrived. Make sure you read the instructions as there have been updates to the valve through the years. Use a little silicone grease or vaseline to help lube some of the rubber seals. Mine came with the extra white ring and seal already fitted , I removed them and fitted another new seal ( it goes at the back of the shower body fixed in the wall) Ok its refitted , but still dribbles ( grrrrr). So refit again still dribbles ( double grrrrr) This goes on for a few days as I refit new seals, And hope it'll settle or I'm being paranoid. I speak to aqualisa who were good and Screwfix call centre who were very good. I eventually exchange the cartridge for replacement with Screwfix, Tallyho! No leaks ( insert victory dance!!! ) Obviously a faulty cartridge so if after a few attempts you replace a cartridge and its weeping maybe it's worth considering theres an outside chance its faulty? Big thanks to chorley screwfix- great team.

Rated 5 out of 5 by from Works a Charm I bought this part for my shower last week. The shower works brilliantly. The part came with screws & seals which was excellent. It just meant that we didn’t have to buy the seals separately.
