Does anyone know how much mains pressure the water company should supply to a house hold.I have complained to my water company (ssww)on many occasions complaning i have no water or very little in my taps.upstairs bathroom sometimes has non any we are unable to flush the toilet.trying to have a shower is a joke at times.washing machine also has problems with not enough water to wash properly.We are on one of those shared water mains ( 1pipe between 4 homes). SSWW has told me and our neighbours that we could pay for our own main but why should we.any suggestions.
