First time for everything...

[gassafe]

After reading on a thread once that someone on here was changing 3 ports by bunging cold feed & vent I decided to give it a go today... It worked 🙂, I was we'll chuffed! My back up plan was alot of towels at the ready, but not needed at all... Happy days...

I have only bunged a system once before, to do a lockshield valve... I'm thinking I need to do it more often maybe...?

Always found that a lin bin full of various plugs and caps was handy if you ever needed them in a hurry.

Be careful as you get more and more confident as you use them and years ago (when we were younger) I used to do valves, did a couple of heat exchangers (which were nervy) and nearly put my back out for the world championship when attempting a cylinder in a tight cupboard.

It had a nice array of gate valves and an old smith valve(blue head) which I could isolate to help but it started to drip and I realised I could lift it, and the scale at arms length over the existing pipes.

Still we all have to learn our limitations. If you're gonna give it a go it might be worth one of those plastic backed dust sheets to give you time to get your surf board.

Bung set and rubble bag under your work area to catch any water, save loads of time and mess. Rubble bag is just in case. Just need to be confident in it.

I have a set of bungs, typical merchant set, excellent unless the tank boss has those 2 lugs on the inside, what's the best way round those? Sometimes they fit sometimes the shoulders of the bung stop on the lugs and won't seal. I don't really want t buy a second set to muller....

Use an old carrot or spud

I still haven't got the balls to try the old bung trick.

Use a bit of 15mm or 22mm, stick a push fit cap on one end and wrap loads of ptfe tape on the other - then you can use it as a bung.

I've used it many a time on the F&E and the CWSC .

I would add just have items to hand etc for a quick changeover and it should go ok.

Hmmm, I'll let you know how it goes if/when I can pluck up the courage.

I'm guessing you normally drain down or freeze then depending on the situation ?

 

[shaunsinky]

im surprised most guys dont bung the system, ive been doing it since my apprenticeship in '99. its a lot quicker and theres hardly any air locks. its good fun explaining it to a new apprentice and seeing their faces haha

Stuff the corner of a plastic sandwich bag with fibreglass loft insulation.
Form it into a carrot shape and use it the same way as a bung.

Got them, last than £20 well worth it

 

[Jimbob]

I fitted a 1/2" sensor pocket on a 3000ltr buffer. They lads couldn't believe how well it worked. Simple stuff really. Yet to try changing anything large like an immersion using same method :S

 

[tommydiehard]

Bungs been using them for a few years myself. I carry a ball of blue tack in the van so if I come across a tank connector with the internal prongs I use this. Make sure it a big lump though as you don't want it sucking into the system....

 

[Reg Man]

some idiot drained the system down to fit the bungs and then said they were pointless.

If you have the same bungs as me, white plastic ones with a thread and a black piece of rubber, i have cut two V shapes into the first part og the bung that goes into the tank connector, Line up the Vs with the lugs and hey presto

 

[plumbandplumber]

If you want to bung the tank connectors with 2 lugs, sometimes you can put the rui=bber bung in a plastic bag before pushing it in.

Been using bungs for years. The old boys I served my time with in the 70s used corks. It amazes me how some guys still drain open vented & sealed systems.
Simple law of physics; water will not drain out of a vacume.

How do you bung a sealed system?

One doesn't Bung a sealed system, as long as you create a vacuum. But you know that?
