Hi all. I've had a 'granny flat' added to my bungalow. My builder, who does his own plumbing, recommended and installed a Trevi Boost shower (it uses the Venturi principle whereby cold pressure 'draws through' the hot water with no need for a pump). Unfortunately, the shower temperature is woeful and the Trevi people have now told my builder that it won't work due to the way he's connected the hot feed.
What he's done is taken the new hot pipe from the top of the hot water cylinder up into the loft, along 7 metres then down to the new shower. (It was not possible to put the new pipes under the floorboards.)
So now my builder/plumber is suggesting a Trevi Therm shower coupled with a pump. I've had a look at the instructions for the Therm (easily obtainable online) and am a bit concerned by what I saw on page 2 - four suggested ways of connecting the hot feed ranging from Most Preferred to Least Preferred. What worries me is that even the Least Preferred way had the new pipe coming down to the floor, not up to the roof!
But bear in mind that I'm to get a pump installed as well (up in the loft). Can anyone foresee any problems with the proposed new shower? My thanks in advance for all responses.
