My house is in a row of terraces. We are number 7 of 8, with the water
supply (a small diameter, old lead pipe) coming down the back of the houses,
with a supply coming off this into each house. Therefore the supply into our
house is variable to say the least.

We have a (cheap) combi boiler and normal mixer shower (i.e. no pressure
equaliser or whatever it is called). The shower is dreadful - water is not
hot enough in the winter and tends to be very low pressure, and it can
almost stop at times (I assume when people up the water supply pipe turn
taps on etc.).

Any ideas please?

Do we need a better boiler, better shower, or are we doomed unless the water
supply to the house improves?

Thanks for any help.
