I like your drip catcher tub👍🏼👍🏼 It works well endfeed, I had a plumb tub before and lent my rothenberger on it and melted a hole in it.  |

Careful with rad water down the bog, I've seen it stain the porcelain under the water level to a crusty yellow scale like its never been cleaned, no amount of scrubbing shifts it.

Certainly saves a lot of time not having to drain down to change rad valves, etc. Have done loads this way on sealed systems. Usually like to turn off the f and r iso valves under boiler in case the aav breaks the vacuum.
How about snatching a heating oil tank valve swap live, tank full of oil, by pulling a vacuum with a vacuum cleaner?
I love it Woody!! I love this guy, he’s one of us👍👍👍 I laughed like a drain when he was saying about the Nuns, great video too👍 Did you catch the part where he disconnected the oil line & he could hear the air being pulled back up through the tank? That’s the important bit, air being pulled in - no oil coming out👍👍👍👍 |

How do you mean? Turn off both valves? I’d like to know this as full drain down is a pain Cheers if you turn the lever valve off to the flow and the return under the boiler,go to a drain off valve on the system,drain about a little out and a vacuum will occur in the sealed system, rocky 👍. That’s how it’s done EF, as long as the lever valves at the Combi are no more than 4 years old or they’ll leak like fuck!!!💦💦💦💦💧💧💧 |

I don't bother with the boiler because if you're snatching anyway it's a very quick process, minimal amount of water.  we all work differently and what ever suits you best and what you feel comfortable with.  didn't know this p.b, going to give it a go👍🏼👍🏼👍🏼👍🏼👍🏼 Same here. I always close the F and R isos as I'm shit scared that when I'm fannying about removing the old olive on pipe the AAV would suddenly let air in and break the vacuum. Result: tsunami. 
Will try it next time.

Even though he's in Americaland, I've learned tons from his videos.
Will start a new thread about him in a mo.
EDIT - there you go, Dick.

View AttachmentCan you pull a vacuum on a pressurised heating system ? It's actually easier to pull a vacuum on these systems than it is on a open vented system, just dump the pressure out and away you go but remember the same rules apply only work on one valve at a time. View Attachment how much water do you normally dump before vacuum is achieved? |

It depends on the size of the system and its expansion vessel but just let it run until it goes to a small trickle and you're ready to rock. 1787034013 yippee |

I've actually done this method by accident, took a rad off in a bungalow,8mm micro pipe dropping down wall then popping out wall on a 90 elbow. The long and short of it, the solder 90 came off the pipe in my hand!i fookin shit myself!small amount of water came out then stopped! I thought someone was watching over me that day.today is the day I know why😁😁😁😁😁😁

If I ‘crank’ a system with a Combi you’re actually isolating the expansion vessel, so I’d say about half a bucket of water before it stops running. The Golden Rule always applies whether it’s bunging an open vented or sealed system; ONE SIDE AT A TIME!! |

I've never tried a portvalve change when bunging the tank,any put falls to look out for? Can the pump be done when bunging?
