Low water pressure

janmp

I live in a flat on the 3rd Floor. The pressure was the cold water is so slow that at times I am unable to have a shower. Also the bath will just fill 1/4 full before the hot water drains from the tank. At times the water pressure is also low in the kitchen. ( both hot and cold) Thames water say they are providing 1 bar to the block ( so will not do anything)
Various plumbers are advising different solutions.


1. Put in a Mains fed thermal store.
2.Put in a Mains fed thermal store plus a pump
2.Install a Salamander pump


I want to be able to have a hot shower when I want, a good bath and a good water supply to the kitchen.


What would be the best solution.

You have 2 issues here:

1. The low water pressure. The kitchen cold tap should be directly connected to the mains, and if that tap is only producing a trickle flow, then your mains pressure is too low to be useful. You will need a pump in order to get adequate flow. You can get shower only pumps, but there are also whole home pumps, designed specifically to boost mains pressure. Something like the salamander homeboost wouldn't be a bad choice.

2. The hot water running out. It sounds like you have only a small hot water tank. If you want a bath, you'll need to install a significantly bigger one. You'd be looking at around 75-100 litres to ensure you get a good bath full. For best performance, you'd want a mains pressure thermal store/unvented heater, supplied from the booster pump.

So, if you want to solve both problems, then you need both a pump and a bigger hot water tank.
