Brass fittings

Very useful things!

Use an empty inhibitor bottle, lay it on its side and cut a section out of it to catch water in.

If we drop the pressure on the combi to do a snatch changing the rad valve.How would i do it when there is a cylinder involved.Do i close the gate valve on the cylinder and the tank in the atic?

 

[kay-jay]

No. On an open vented system you use bungs on the feed and expansion pipes to create the vacuum.

I need to remove my rad from my bedroom because some numpty that lived in the house before us stood on the radiator while throwing things out of the window and pulled a rad bracket out of the wall.The problem is i have a low lying window ledge and the radiator sits low to the floor so i think getting a bucket in there will be near impossible lol

Thats what your thumbs are for. Close the valves put a couple of rags under the ends, split the nuts and lift it out full of water.
Never had the need for a wet vac in my life and i doubt if i ever will.

I don't have one either. They are cheap though but £40 can nearly get me drunk...:beer:

True old school :yes:

Put a new radiator on a combi system the other day and piped it in. Dropped pressure to 0 bar. Removed stop end to start soldering and water just came out loads of it so I'm assuming I didn't create a vacuum. The boiler was a woster botch 24kw small thing don't know the exact model but it was a new one. Does this have an intergated AAV? Explaining why the water was escaping.

 

[kay-jay]

Possibly. On a combi system though i see no reason not to drain down if not confident. Just bill for redosing inhibitor.....
Can drain and refill in no time

 

[Dannyparty92]

Job for my father so not charging. Nah no probs draining down and filling is easy there never have any problems with air locks it's a bungalow with surspended timber floor so pipe work just goes down from combi primary's shoot across the bungalow under the floor and rads are just teed off the primary's. I'm just interested to know. That's a shame as I'm not GSR so I can't remove the boiler case to shut the AAV so I have to drain down ha.

Start at the start. Bungs and soldering are a no no. Use the correct materials for the job......in this case compression or dare i say it ..... push fit. Get the connection done quickly and cleanly

Do what I do to drain rads - wrap a rubble sack around the pipe and undo the nut. Simples

They have an AAV on the pump, turn off the isolators underneath

 

[AWheating]

good idea to keep a paint roller tray in the van for times when the rads are low to the floor and you cant get a tub under the valve. Or place the wet and dry vac nozzle there.

 

[Dannyparty92]

So just turn flow/return isolators off under the boiler?

ooooh controversial, many are of the opinion that once used these iso's are prone to leaking

I'm one of them, depending on the boiler and visual condition of them

 

[Dannyparty92]

I'm assuming many of you don't like doing that?

 

[tom609]

if yu snatch it be sure its the same valve to be on the safe side i use a bung in the tank oulet and a cap on the vent you only need to drain about a gallon of water off then

 

[SimonG]

Valves in boilers tend to be left alone as far as I'm concerned, unless you are looking for the indoor water feature look.

 

[Dannyparty92]

Understood!
