Can anyone advise on how to fit a Flow Valve Assy and Solenoid Valve Assy on a Galaxy G9000S 8.5Kw shower unit. Water is leaking at the base of the wall mounted box. I can buy the parts online for about £35.00 (Unless you can do better) but need some help to fit them. Can't be that difficult! surely.
Thanks.
