    Hi guys,

    Having an extension and an extra shower will be added.

    We currently have an old potterton 24 eco combi boiler with a mains flow rate of 6 litres per minute which is quite low.

    We already have an electric shower so assumed the new one should be that.

    Could someone guide as to the best choice between an electric or mixer shower please?

    The boiler may be being changed as part of the work.

    Thanks.

    Generally speaking ,a thermostatic mixer shower valve fed from a combi boiler will outperform any electric shower. Having said that ,with 6 ltrs per minute flow from what you have is pizz poor !! Time to consider a new and more powerful boiler. What is your incoming water mains pressure and flow rate?

    Hi,

    I don't know the mains pressure but the flow rate is 6 litres per min. This was calculated using the cold tap located directly by the incoming mains water.

    I assume that is expensive?

    Are main water pumps any good?

    Depends on the reason why you have such a poor flow.Is the mains water pipe ( the underground supply) Lead by any chance ? Does the area / neighbours also suffer from the same problem ? You should engage a plumber to have a look and discuss your options.

    Thanks. I'll speak to my neighbours and find out.

    Houses were built in the 60's.

    Unfortunately I don't have any details other than it runs from the curb under to the back of the house.

    I'm not an expert but I assume it must be the main supply as the cold tap in our make shift kitchen is next the to stopcock so rules out any internal probs.

    I also checked the water meter outside and the valve was fully open.

    Yeah, check with the neighbours and see what they get at the tap, you could have a half shut mains stop tap or a problem with the mains. most suppliers these days will supply at least 9L/Min as part of their contract with you. If not then it's for them to sort out, unless it's an issue with your supply pipework after the boundary/meter.

    Though I'd report back.

    Water board came out. Flow at the road was 16 l/min. Flow at outside tap in garden was 12 l/min. Flow at the kitchen sink was 6 l/min.

    Now there isn't much pipe work between the stopcock and the two taps mentioned above.

    Plumber is going to investigate. Surely this rules out the pipe from the road to the stopcock?

    Thanks

    Yes it does ,to a degree.The kitchen tap, or the pipework to it ( possibly flexible hoses maybe ) is restricting the flow.

    Interestingly the taps everywhere in the house have poor flow except the outside tap.

    The plumber is replacing the stopcock as its old and leaking.
