Heater tap refurb
Tap had green scale on the outer casing - looked like a small leak it was coming up the centre spindle. I've oiled the thread and wound the spindle a few times to help seat the brass top blocker. Hope this will work - but just wondering if there is a seal or 'o' ring somewhere, anyone refurbed one of these before?
That's strange R2, the damage doesn't look so bad from here!

Re: Heater tap refurb
No- not plumbers mait, what am I thinking. Going to try a strip of muslin cloth soaked in oil.

Hemp and good old-fashioned water pump grease!

Re: Heater tap refurb
PTFE tape will cure it.

Re: Heater tap refurb
(In my opinion) Graphite string is the correct material for hot water or steam packing

Re: Heater tap refurb
Roy, why should you not use PTFE tape? Using string and other thicker materials will stop the tap opening fully, restricting water flow to the heater.
Mine has not leaked since I used PTFE tape on the spindle 2 years ago.

Re: Heater tap refurb
It's just not bulky enough on it's own - maybe you just added it to whatever is below ?

Re: Heater tap refurb
While researching a similar problem with a house tap I came across Loctite 55. A sort of cross between string and PTFE. Maybe that will be better than just PTFE?

Re: Heater tap refurb
Below the gland nut in the body of the tap should be a hole only big enough for the shaft to come through so when you fit the sealing material in and the gland nut you compress the sealing material around the shaft which is the seal, so what you put in will not affect the amount the tap opens, if you turn down the nut too hard the tap will be stiff. Turn down the nut util you get no leaking, then if later it leaks again you will be able to tighten down again and again until it needs repacking.
