Hi, My semi-detached house has a shared water supply and regularly has low pressure. 90% of the time it is manageable however when my neighbour uses water the supply drops to virtually nothing, this cuts out the combi boiler making a shower impossible. I have had the water company out and tested the supply in the street, which is more than sufficient. The cost will be around £1-2k to put a new pipe to the property. This is something I don't want to pay for. Therefore I am looking into other options. Does anyone know if I can put a cold water tank in my loft and connect this to the combi boiler. This will mean I can shower without the worry the water will disappear half way through. The hot water will then all come from the tank and the cold water from mains. If I can do this I understand the pressure from the tank will not be good, but anything will beat what I have currently got. Any advice is appreciated.
Cold water tank supplying combi boiler?

The problem will be getting hot water pressure, you would need a rather large tank, very high up.
Also you shower will struggle as the hot and cold won't be balanced. I,e different pressures.
I'm assuming as you have a combi, you dont have a tank?

There is no tank at the moment. I was thinking about getting a 25 gallon tank but there would not be a great difference in height between the loft and boiler as its located on the landing.
Fit a tank to an electric shower that is suitable for a tanked cold supply. The shower will have its own integral pump. You will always have a good shower.
There are other options available but could be costly, like an accumulator or break tank and booster set.
A cheap but possibly not very good option would be a Salamander home boost pump, results are not always good but they can be fitted on mains or at cold inlet to combi boiler.

If you have a reasonable static water pressure say 2 bar.
You need a non return valve where the water supply enters your property.
You then need say 100-200litre of accumulator tanks somewhere in the house. This can be 1 big one or a number of small ones.
To store a quantity of cold water at pressure.
Fit aerator taps these use less water and therefore spread load better when more than one tap is in use.
