I just moved to a new place 3 months ago and there seems to be a problems with water system. 1930 Terraced house in Surrey.
The cold water pressure going into the house does not seem to be too too bad, however when I have 1 tap running cold or hot water and I open another tap in the house, the tap which was originally running first stops running water.
1st - I turn on the tap in the kitchen sink.
2nd - I turn on the tap in the bathroom.
OUTCOME - The water coming out of the tap in the kitchen nearly stops (only a little bit of water comes out of the tap)
This means if someone is having a shower and another person is washing the dishes it all goes wrong.
Any idea what could be causing this?
Thank you for your help in advance.
