    Vent/Expansion and makeup pipe.

    Was looking round a new house build and as a one time Plumber was looking at the pipework in the cylinder cupboard. I was chatting to the Plumber and queried the way he had positioned the cold feed and expansion pipe. On the main pumped flow to the cylinder he had branched off into the...

    New boiler advice

    Dave, I presume these are pressurised ones with simply a mains feed. I fitted many of these in industrial sizes of of up to 800,000 BTUs and they were cracking boilers and mainly Italian. They used a separate expansion tank bolted to the wall. That could be a good option and will look into...

    New boiler advice

    Dave..The existing gas back boiler which does the job is 40,000 Btu in old money which I find is 11.7KW. The bathroom is large enough to site it well away from over the bath. The condense pipe would be able to go down the side of the house into an existing drain gully. So I suppose it would...

    New boiler advice

    Thanks for your replies. I thought the glossy brochure and buying my old boiler back was a bit too much. They can have it for free when it comes out. Looking for suitable places, would an outside tiled wall of the bathroom be a suitable place for installation. Would I be right in thinking...

    New boiler advice

    I am a 6 year time served plumber & heating engineer, ex Corgi and retired for quite a number of years. I’m looking for general advice as follows. When we moved into our present home some thirty years ago there was only a coal fired backboiler for DHW. I installed central heating using a Glow...

    Copex flue liner

    Sorry I have not answered before but was busy. As regards the points score I understand the system and would reach the necessary amount to jusify the replacement needed. However I will not involve the system and simply replace myself. wemyss

    Copex flue liner

    Will shortly be replacing my Gas back boiler with a new one. The new one is less in height making the 5" flue liner probably needing extending. I have a few feet of this and wondering if there is a commercially made fitting to extend the liner, or if I have to use a piece of rigid off the...

    Cast Iron Soil Stacks

    Brumylad..Before the introduction of Titan and bolted glands we used to lead caulk cast iron water mains. Thes had to be done horizontally of course and the procedure was to first of all caulk tarred hemp rope in to the joint using the lead caulking tools you have bought. Always a small...

    avoid draining

    Should perhaps add that the above is for a conventional system and would not include a Combi boiler or a pressurised system. The tank to isolate in the roof space provided it is a conventional system would be the small one only. If there is no isolating valve on the feed out of it you would...

    avoid draining

    Yes you could change the rad without draining all the system down. As you suggest if you have a valve on the supply from the tank you would close that down. Turn off all the rad valves on all the upstairs. With a bowl underneath the rad which is being replaced crack open the union and allow...

    Anyone know anything about Freeview?

    Its a bit hit and miss Brightness. As you probably know you can go to their site and enter your postcode to see if you can receive freeview in your area. Having said that a mate who lives in a town 25 miles away found he was not able to receive in his area but went along and bought one. He...

    Replacing back boiler

    Steel pipes

    Jdey. When I said I crushed this pipe with my hands it was because it had corroded so badly. If yours is solid and hasn’t corroded I wouldn’t replace it unless you were experiencing leaks. Regarding the corrosion of copper this isn’t really so. Copper will oxidise and turn green exposed to...

    Steel pipes

    Jdey. On the positive side the steel tube in the Admin Block is still there today without any problems. I retired ten years ago and by then was off the tools and was the principal Engineer for this site. I had always dreaded the thought of having to replace this pipe as it housed 200 Admin...
