    Tiny black ants in 1st floor bathroom

    With difficulty. I could perhaps remove the side of the shower tray to avoid removing floor tiles. Downstairs neighbour has also found the same thing. I checked the basement (where the pipes go up from) but no sign of any there.

    Tiny black ants in 1st floor bathroom

    Our flat's bathroom is on the 1st floor of a conversion (in the centre of the house with no external walls). Since yesterday we have noticed several tiny black ants each time we go in there. I have noticed that they are coming out of a small gap in the mastic where the bottom outer edge of the...

    Vented central heating system queries

    Are you referring to the two hot water cylinders? I thought that these were fed by the other cistern.

    Vented central heating system queries

    Thanks denso. That has put my mind at rest a bit. I think I will reduce the pipe length a bit (to above overflow level) so it cannot go below water surface, even if ball cock valve doesn't operate properly. What are the implications of this as it is - oxygenating the water in the cistern ;) and...

    Vented central heating system queries

    I live in an old house that was converted into flats. Our flat has a combi boiler as do 4 of the other 8 flats. What I didn't realise was 3 of the flats are still on the old communal heating/hot water system - I think that this is a vented system. In the attic there are two plastic (old...

    How to flush a heating system with mains water.

    Sorry to bring up an old thread but I had a query on this. Had a boiler service yesterday. Engineer added some cleaner to system at the end and instructed me to run the CH every other day for a couple of weeks. After that time I am to drain down the system, clean the Magnaclean, refill system...

    Very slight leak from towel rail connection point

    Fully understand now. Thank you very much. I didn't know it was called a compression fitting which is probably why my googling wasn't being very successful.

    Very slight leak from towel rail connection point

    Thanks oldbuffer. I'll leave it until things go back to "normal" I'm trying to get my head around how these connections work. I have been googling and found out about olives - not really sure how they would be water tight by looking at them! I've added a sketch showing where the water is...

    Very slight leak from towel rail connection point

    I have found that the towel rail radiator connection leaks very slightly. It doesn't drip, it is just slightly wet at the points shown in the photo. The leak is so minor that I am not getting any noticeable pressure loss in CH system. What approach is best to take?: 1. Do nothing as leak is...

    Boiler flue inspection point (and central heating inhibitor) query

    I have bought a Sentinel X100 test kit (obviously might be completely pointless, as I don't know if that was used). If it shows that it is fine, I will do nothing. If not, I will drain the system and add new inhibitor. I don't want to do more harm than good by potentially mixing inhibitors. Does...

    2x internal stop cocks stuck open

    Thanks for your detailed replies. I am going to give it a go but check I can isolate from outside first.

    Boiler flue inspection point (and central heating inhibitor) query

    Thank you for your responses. I am going to call Independent myself and ask about inspection point. As for inhibitor, I am going to get some Sentinel X100 and add it via the Magnaclean. The Sentinel product is one of the recommended ones in the manual - although I cannot know if this was the...

    2x internal stop cocks stuck open

    Hi everyone, I have 2 inline stop cocks for the cold water supply under the sink. I wanted to check that they were operational in case of a flooding emergency. However, both seem to be pretty well stuck open. Being in London, I am thinking this is a limescale related issue. In fact you can...

    Boiler flue inspection point (and central heating inhibitor) query

    Hi everyone. I have a couple of boiler/CH related queries. I had an engineer come round to re-pressurise the expansion vessel fairly recently, as the CH pressure kept rising drastically; causing the PRV to activate. He fixed this issue but said that the boiler was not technically serviceable...

    Boiler loses pressure suddenly and cuts out when heating has been on

    We have an Ideal Independent C24 boiler. Since we moved in just under a year ago we have had to re-pressurise a couple of times using the filling loop; which I have read is fairly normal. The other day I needed to re-pressurise again. I may however have accidentally left the filling loop valve...

    Leaking shower tap

    I've noticed that the shower tap has a reasonably quick leak (a constant drip); only when the tap has been opened and the shower is running. I removed the tap and have highlighted in the photos where the leak is coming from. As someone with little (no) plumbing experience could some tell me if...

    Timer light switches are permanently on

    Hi everyone In the communal area of the flat, we have timer switches (about 5 in total) which used to switch on the lights for a couple of minutes before switching them off again. Since returning from Christmas, the lights are permanently on. I have gone round to each switch to see if any were...
