Drain down

[rocketmanbkk]

Went to drain down a vacant house yesterday.

Toxic gave me some advice on a problem so thx for that.

Cwsc in loft, stopcock half way up wall, no doc. Turned water off & ran taps, shower, flushed toilet etc. All ok. Checked in loft, no issues.

Ch - doc on rad in hall, connected up, all valves open, starts draining, vents upstairs open, all lovely then nothing, vents downstairs spouting water when open.

See another doc under boiler, good news, connect up, open & flow starts then nothing, ds rads still full, crack a nut, loads of water.

All the rads ds had like a nut on bottom of lock shield side valve but it was a case of take the nut off & connect hose quick. Had to do rad by rad ds. Pic of nut.

Anyone got any comments of if there was an easier way to go ds rads? I could've sucked water out with vac I know.

Cheers

You could try and pump air into the ones full of water or just take them off and drain the long way

Thx Shaun. I've never seen these little nuts before on a valve. The house is in need of a refurb as probate so I'm guessing at least 70's with the kitchen 60's!

All experience

Turn both valves off to rad, open air vent to relieve pressure, replace air vent, remove nut from drain point (wont get much water spill if air vent is shut) fit hose and open valves on rad

At just under £4 its worth having one or two on the van just incase,
saves messing around draining and dropping a rad off if your on your own

The boiler was at waste level down stairs, sealed system as no f&e (?)

The pipe work from the boiler went upstairs first

This, with a regin drain hose and a few cable ties. Just looked at pics again, spot on. As you were.
