Hi all,
I have an immersion cylinder in the loft room to supply a shower, bath and wash basin only. There is also a WC and cold taps of course.
1) For many months there has been a slow trickle of water out of an overflow pipe onto the flat roof below. It feels warm, but not obviously hot, and I'm not sure which part of the system this overflow come from.
2) I recently replaced a (wrongly specified) shower pump with a proper negative head one, which now activates as it should, except it also kicks in for a second or so every half hour, as if there is a leak in the system.
3) The feeder cistern above keeps filling (float valve never quite closes), but it does not reach the overflow.
4) the vent pipe from the cylinder up to the cistern is hot to touch. IS this
I thought 1) and 2) were unrelated but now I think the shower pump is topping up some leak or overflow, but I dont know where from. Any ideas?
