    Hi. We are currently having an extension built which includes adding 6rads, removing 2 rads, a towel rail along with a basin, toilet and shower.

    Since this additions to the plumbing we are having a number of issues:

    • the heating is all over the place - cold rads which will then be hot the next day and other will them become cold.

    • Rads that are only like warm and/or cold at the bottom
    • cold water taps that are from tanked water are now warm and with brown water
    • overflow from the larger tank above the cylinder is running when heating is on.
    • Water in the larger tank is warm when boiler is running.
    im told by the plumber that all he can think of is the coil in the cylinder has a pinhole in it but this all occurred as soon as they finished there work so am I being fobbed off!?!?

    what also happened when they drained down is they failed to turn the boiler off timer and it kicked in (mistral 35kw oil boiler). The system wasn’t flushed or anything like that either.

    I want to make sure it is this before spending money in a new cylinder so and help would be really appreciated

    The brown water could be the result of pinholing, and with the overflow running could be. Do you have a 3 port valve?

    Yes It appears the CH water is findings its ways into the tank above the cylinder??

    not sure about the 3pv. Where would this be? I know there’s an old control valve under the floor boards up there as from memory once upon a time the previous owner had a single rad connected to the HW.

    It would appear you do not have one, although not sure how your heating system works, and you certainly shouldn’t be getting any ch discharge into the cold feed for hot water.

    Maybe this will help? Just drawn this out and currently have the cold taps on with the ball valve held up so I can see which pipe is letting the water in.

    Ok so the larger of the two tanks is now empty and it appears that the pipe that connects to the cylinder is feeding hot water into the tank?? See attached pic that I’ve labelled the pipe. If anyone can offer any advice why this would happen please do.
