Does a Bristol power shower have a filter fitted

Several researches confirm that tap water may contain a high-level of Chlorine which is responsible for skin irritations, certain types of cancer, as well as beauty disasters. Considering these health hazards untreated tap water for bathing is not a good idea. In this regard, fitting a shower water filter with a shower head is a simple yet amazing solution to use Chlorine-free water.
If the product is new to you, get a more detail discussion here.

Tell us what type of shower. Power shower with a pump? Mains water power only? How old is it? Who fitted it? Does the control valve feel like its working properly?

You need to install water pump, the shower water pump is not to powerful tu make sunction.

Hansgrohe hand showers have filtration sometimes on the inlet side of the hand shower. You must unscrew the smooth conical nut from the handshower to expose the filter and the flow restrictor. If your hand shower is not equipped with a filter gasket, you should use one to protect your hand shower from the particulate.

Filter gaskets can be used at your body sprays and shower head as well if you have them. If you have a Hansgrohe thermostatic valve you don't need the little filter screens, because the valve is filtering the water good enough. We do not recommend opening your handshower for cleaning. There would be a strong chance you may not get it together again, or it may become damaged.

If your concern is with a buildup of lime on the spray faces, you can use a decalcifying agent to dissolve the deposits, but do not soak for more than 10 minutes and then rinse well with clear water.

Only on normal head.If you have normal set-up hand held diverts before filter.From the stand point of a 35 yr master plumber,your wasting your money,unless you gulping a lot of water while you shower.Lots of gimmicks out there,like drain cleaning chemicals complete waste of money

sounds like the pump is broke. better off just replacing whole unit unless you order new pump from triton.

What type of valve is it, is it a tmv2
