heating systems with no Drain Valves

[GQuigley67]

this seems to happen quite alot and it can be a pain, happend to me yesterday and I had to drain down from lockshield valve via a washing machine house into a walk in shower tray, then had to suck the rest of the water out with a wet vac and some cellotape to create a seal lol otherwise I would never have been able to solder the joint, all in all took quite some time

anyone got some tips or experiences they could share on this situation ?

Self cutting washing machine tap.

Just use one of these to drain and then remove and fit a permanent one when empty

They are only a temp drain off, like I said, once drained, fit a soldered drain off in its place.

I get them from my local merchants, but bes do them, £3.37 plus vat, bargain and can save loads of time. I always carry one in the van just in case.

easy solution like you come across it all the time , use a serviceman valve with a drain off on other end, drain rad lift off wall then fit serviceman onto valve hey presto a easy made drain off to use anytime .

 

[royston]

Normally ill take rad off at lowest point and drain from valve, then recommend a valve with built in drain off fitted for future purpose.

I would normal connect washing machine hose onto TRV/Lock Shield then if needed extend it with washing machine valve, pipe and hose with jubilee clip, assuming the valves have a 3/4" connection but would defo be purchasing one of those self tapping drain cocks !

If there is easy access you can fit them on the tail under the floor boards - so cant be seen. You know they are there if needed in the future!

 

[pobsdad]

If you're lifting floorboards,just cut a pipe and stand back,but don't let the customer see it!And never in a third floor flat!

Is the self cutting drain off for 15mm pipe only

 

[Blake]

i have one of these in the van for this type of problem.

Top tip: Dont try and cut through heavely painted pipes or you will be sorry, ensure you clean off pipe first. they will blunt up the cutting edge and crush the pipe if you dont.. also dont use them more than once as the self tapping cuttter is only good for 1 job as a rule of thumb.

i have one which does 15 and 22mm, the screws are longer. used it for years with no problems
