I can recommend: Do NOT use AQUALYSE for water filter fitting!
Just thought you might want to know if it recent experience with AQUALYSE.
We asked AQUALYSE to come to quote for a water filter system for our hard water supply.
The bloke who came was very pleasant and polite. However, during the initial investigation he tried to force and broke the main stopcock, and then dismantled it. When he couldn't fix it, he admitted he wasn't a plumber, and walked away leaving us with no water supply at all.
We were fortunate that a local plumber came to our rescue and almost 10 hours later we had water again.
We have sent Jonathan the invoice from the repair but he has chosen not to respond. We have repeatedly asked him for his insurance details to claim off his business insurance but he is ignoring our emails.
It was an expensive mistake and very upsetting. Steer clear of AQUALYSE and make sure you get a real plumber for installing any water treatment system you need!
