where to drain down

[ekythump]

I have an old solid fuel back boiler which is leaking,I have looked all over my house and out side my house and there is no drain valve.
As I will be replaceing the heating system and the hot water system I do not want to go to trouble of putting in a drain valve. I know that sounds lazy but all I want to do is get it all out. Can I just empty the water from the heating system into the air gap under my floor by cutting the heating pipes which are under ther and putting a hoes into the top of the hot water cyliner and siphoning the water out of that?

I would not recommend it but it would certainly work !!

Thanks for the reply.Why wouldnt you recommend it wouldnt the water just dry up or evaporate?

 

[Terrywookfit]

Yes of course it will!!

Just remember to turn your stoptap off !!

As a respected and competent pipestrangler,I should not recommend publicly something that is only done when the customer is out !!!

If its your house and you feel happy about it W T F !!

Ps Make sure there are no electrical JB's that can get wet !!!

Put a self cutting tap into the pipe low down near the boiler then run a hose from that to drain it.
Got to be less messy!

Agree with P-P. Use the type designed for washing machine hose and you can screw one of them on and not lose a drop.
By the way they go onto 22mm pipe if you use longer bolts.
But they ALL seem to be made with the cutter part too long - anyone else found that?!

OR, remove one rad (ok catch its water in a roasting /paint/catlitter tray) then you can screw a garden hose connector straight onto a 3/4" rad valve union.

You could find a drain off when you get access to your boiler. Sometimes they can be found at the side of the chimney.
Its been a long time since I changed a solid fuel back boiler but what I used to do is to drain off the cylinder first.
Then where the pipes lead into the boiler I would tap a nail into the pipework. I would then remove the nail and a jet would shoot perfectly into a bucket using the nail again as a plug while I swapped buckets if necessary. Once the cylinder is empty there's only a bucket or two of water left in the pipes
