I have a hotwater tank on the 1st floor of my house and a cold water tank in the loft. Hot and cold water pipes are both 22mm and are split in the loft to feed 2 showers on the 1st floor. One of the showers seems to be designed for low-pressure and the other for high pressure because the low pressure one has adequate pressure while the other one barely has a trickle. I want to install a pump to improve the situation but I'm not sure where to do so or which make/model to use. Do I install a pump in the loft before the pipes split so that the supply is pumped to both showers or do I just install one for the shower that needs boosting and if so where should I put the pump? In the loft after the supply has split or in the access cupboard which gives access to the shower pipe connections of the shower that needs boosting? Any help appreciated as the plumbers I've asked have quoted me over £1200 for running new pipework etc from the hot water tank which it beyond my budget so if I can tell them exactly what I want then hopefully I can get a more reasonable price or if I can just add a pump using the existing pipework and someone can recommend exactly what I need in terms of pump make/model, location of pump and any extras I need such as valves etc, then I can do it myself. Thanks!
