The pump has started to only work intermitently. The pump is making a noise and gets very hot but is not pumping the water through. It then kicks in all of a sudden. It sometimes kicks in if you turn the shower on and off but even that is now not working as often. It is 6 years old. Is it worth getting it checked to see if a part needs replacing or should I bite the bullet and get a new pump? Any advice welcome. Thanks.
