Rad valves and bung kits

[villa_tom]

Hi all

Got a lot of rad valves to change in various houses tomorrow - think i've drawn the short straw - anyway, I have a bung kit on the van and never used it, but was just wondering if any of you guys have?

I've no problem with the drain downs but would use bung kit if quicker

Any advice appreciated

Tom

I only use them on quick repairs and have cap ends standing by just in case, and never leave an open pipe unattended when using bugs. And only on indirect systems. Can save a lot of time though and overall a good bit of kit.

Thanks for the quick reply, if i where to use them how much water would i expect to get out of the system if changing a downstairs valve perhaps???

Hi use them all the time about a bucket full, when taking them out the tank remove the cold feed one first then the vent

Not telling you how to suck eggs? Only do one valve at a time! I was in the merchants once and overheard the following experience. The engineer had gone in to change rad valves the system, bunged it, then two engineer's ran round changing valves and end up with gallons of water on the carpets. The fitter dragged the staff member, who sold the kit, across the counter and gave him a right hard time on what a load of crap these bungs are. I pulled him off and told him the errors of his way's. Seriously Bung Kits are gret time and money sving tool. Saves time on draining and replacing inhibitor.

Only change one valve at a time if you go the bung way, if changing full house I would drain down

Thanks all for your quick replys. As its just one valve in each house (6) think i'll test the bung kit out on the first one and if i like it i'l go from there otherwise i'll just stick with the draindown

what your saying is you loose about a bucket from each tail pipe during the swap over?.
what about the rad?.

i would not risk it ! drain down fully and use my wet and dry if there is rads on drops ! trusted method that will not let me down !for the sake of refill in 20 min could end up in deep sh@t and not make any £ !
