    hi

    brand new thermostatic mixer shower, fitted all plumbed in correctly, however there is literally only a dribble that comes out the head, the cold comes from a 42 litter tank in the loft 4meters above height of shower, and the hot comes from the cylinder in the cupboard 2m from the shower,the shower is downstairs basically

    any ideas as to whats going on? why so little water?

    cheers guys in advance

    Is your shower designed for low pressure use? You have about 0.4 bar there.

  4. Or airlocks? Do you have any pipework that goes up and over?

    Have you tried removing the shower head and lowering the hose to see if it kicks in?

    I have had the situation before where I have had to remove the valve to get the water flowing through. When replaced it was fine.

    Hell, you still have a sense of humour....!
    A shower pump, which pumps both the hot and cold supply may be for you - I've never fitted one though so it's over to those with a brain cell :p

    yes mate, not the end of the world can be sorted I'm guessing,

    ok so, what can you guys tell me about shower pumps, there is quite high pressure on all the taps around the house.....im guessing the water pressure will be increased on them as well, can they be reduced so when little ones are doing their teeth not flooding the bathroom :D

    The pump will purely increase the pressure and flow to the shower. It'll need to be fitted inline from the tanks to the shower. The small header tank in the loft may need to be increased as well, that will soon run out with a pump
