Pain in the bum they are. I almost had a leaker yesterday after letting some pressure out of an over pressurised boiler.

Still a washer mate....have a good old clean up with a wire brush at the same time. Right old pain to heat up wettish end feeds to replace. Can be done but it is the rubber that is wearing out not the brass bits. Seat can be dressed with a large flat screwdriver.

just be wary of a dezincified doc, tapped one to loosen the washer last summer and found myself with my finger over the sheared off doc and a cylinder full of hot water! no one else in the house and all i had was a screwdriver, short length of hose into the loo, and a multispanner! after 10 mins i decided to stuff my shirt in the hole with screwdriver and was trying to take off shirt over my head with one hand on leaky doc when owners came back so I utilised his finger whilst I got tools and long hose to syphon out cyl. be gentle with old docs is my advice:willy_nilly:

Happened to me with a manual air vent, vent hit the celling of the airing cupboard and something hit my underpants

Never had a drain off leak when it hasnt been used?!!
Are you taking the washer and guts apart before you solder them into a fitting?

Went to undo doc on cylinder, pipe snapped someone used a 1x3/4 iron bush
didnt do any good for my blood pressure i sure did sweat. In the end of panic my mate smashed a hole in top of cylinder and put drain down hose in. And would you believe it the brass fitting would not come out on outlet

I always change washers if I have drained down from it saves you more time in the long run

Worse is those heating element tees on towel warmers.

Manufacturer instructions say the Rubber O Ring is adequate, however ive always have to ptfe them and paste!!
