Bodge(s) for leaking isolating valve?
Any suggestions please for what to try or not try to bodger an
isolating ball valve by the CH pump which is leaking (not just oozing) past the screw? Background is that CH pump failed yesterday morning. (Sods law as whole boiler is scheduled for change next summer.) I drained down and replaced the pump head and the system worked OK. But I must have caught the ball valve in the process (which did involve some effort to free the old pump head after 30-odd years) as it is leaking freely past the screw. And I do mean leaking, not weeping. A proper fix replacing the valve - would be a buggeration as the pumps crammed against the pressure vessel, with a bypass weaving round them, in a corner of a cupboard, with connections not touched for 30-odd years. And of course theres no clue as to the make/length of the valve. So given its only got to last a few months I wondered about bodges. Ive failed to find any on the net. But Im open to suggestions. ('Er indoors has already covered angle grinder as in fall on it if the heatings not fixed.) photo of the other valve: https://www.dropbox.com/s/fo86qz1368...valve.jpg?dl=0 -- Robin reply-to address is (intended to be) valid |

Bodge(s) for leaking isolating valve?
Self amalgamating tape might do it and at least you will be able to get to the valve to turn it off should the need arise.

I agree as it's not under mains pressure, I have just had to use this on the stem of a towel rail valve where the gland failed and it is still holding after 3 weeks. I'll drain down and repack in the summer. It has the advantage of being removable. AJH |

I assume that by "screw" the OP means the on/off slot not the large flange and nut that connect the valve to the pump. If that latter they do need the faces ot be cleaned off and a new fibre or rubber washer to seal... I'd start the SA tape around what is available around the screw for afew layers leaving a bit protruding, squish that against the screw and wrap several layers right round the valve over the screw. If those tend to form a tent from screw to body wrap more around to tighten it up. -- Cheers Dave. |

It will depend on the pressure behind the leak though. Thanks to all for their the suggestions - if only for the entertainment value  2-part epoxy was my uneducated guess (bearing in mind the temperature) so I'm going with that. But not just yet. Having decided on epoxy a quick look online showed Toolstation had Everbuild Plumbers Epoxy Aqua Repair with 3 in stock at my local branch. I've just returned empty handed as I'd missed that they also showed them as "Currently unavailable". Seems they've had reports of problems with the batch so have recalled the lot. https://www.toolstation.com/shop/p59...rbuild%20epoxy I hope I'm more tired than I'd realised.

Roger Mills expressed precisely :

I've had ball valves which have miraculously re-seated themselves and stopped leaking when I've done that. I would agree with that, it may just be a bit of grit or limescale has worked into the sealing surface. Operating it will break it up and allow it to reseal (maybe). |

Those 1/4 turn valve pump unions are spawned by the devil. I stopped using them and moved to gate valve type. Even though they sometimes failed to shut off tight at least they had an accessible gland on the spindle.

Get a small piece of soft rubber/plastic and put over leak, held in place by jubilee clip(s). Or use a small G-clamp. If it leaks a bit you may have to de-pressurise the system and put some jollop under the soft plastic/rubber |

A proper fix replacing the valve - would be a buggeration as the pumps crammed against the pressure vessel, with a bypass weaving round them, in a corner of a cupboard, with connections not touched for 30-odd years. And of course theres no clue as to the make/length of the valve. So given its only got to last a few months I wondered about bodges. Ive failed to find any on the net. But Im open to suggestions.

Get a small piece of soft rubber/plastic and put over leak, held in place by jubilee clip(s). Or use a small G-clamp. If it leaks a bit you may have to de-pressurise the system and put some jollop under the soft plastic/rubber Update, screw is not flush. Cut head off flush first (with hacksaw or angle grinder).

Background is that CH pump failed yesterday morning. (Sod?s law as whole boiler is scheduled for change next summer.) I drained down and replaced the pump head and the system worked OK. But I must have caught the ball valve in the process (which did involve some effort to free the old pump head after 30-odd years) as it is leaking freely past the screw. And I do mean leaking, not weeping.
