Client Feedback


Wandsworth is notorious for bad water pressure and my mains pressure has been reduced again. I was at my wits end with no water in the morning or early evening. Even on good days I would just get a dribble to shower under. The Challis Boost that I have just had fitted has changed my life, real power showers when and where I want!

Ms Ashton (London)



Just wanted to write a quick note to thank you and Russell for your advice regarding the installation of my Challis 310.

I fitted it on Saturday and the difference it makes is unbelievable - I think I'm going to have to pinch back some of my taps the water is coming out so fast!
