Been asked to fit a Trevi boost as part of a bathroom instal. Just a couple of points you may be able to answer for me. Best practise assumes that separate supplies are used but this isn't an option. Trevi do state that it can be ran on shared supplies but i was wondering if anyone had used this method and more importantly what the results were. I know it will depend whats there at present in terms of supply pressures/flow rates but ball park will do. There's a cylinder on the floor above and the rest is mains fed. I'll be coupling up under the bath as the 1st draw-off on the hot supply.
