Loft Tank Plugging / Bunging Up. So You Can Do Work On Your System With OUT Draining Down. 2021

[@thehairydiyer]

Great tutorial! Gonna do this today in order to remove a radiator before decorating.

[@fionnan2811happy]

Wine bottle corks do the trick too.

[@somnath606]

Very simple language and wonderful explanation. I can do 3 jobs now!!. You are a star!!

[@krtgiroto]

Great video, but I can't find the rubber bung, tried BQ and Toolstation... Staff guys looked puzzled when I asked! I'll use a couple of bottle corks as suggested down, should work just fine I hope.

[@martinwarner1178]

Wow, great instructions, I did not know about leaving vent pipe bung on until the system has filled. Top class act you are Sir. Peace goodwill.

[@metarich2451]

Great video Mark, helped me immensely.

[@arfadaily8050]

Perfect ! I had the bung set from years ago, but had completely forgotten how to use them. The job of fitting a new rad plus new valves went perfectly. I would guess that the total amount of water lost from the 'system' once the rad was drained and gone, was about half a mug. It's a very clever way of doing jobs like this and I would absolutely recommend it - after you first carefully watch Mark's excellent video right through ... 😀

[@whitefields5595]

I’ve been bunging the tank outlet, but never the vent pipe. Thanks for this, really useful

[@andrewcosmatos339]

Great video Mark, especially the last bit explaining how to un-bung without air rushing in!

[@lexsper]

Excellent explanation. Many thanks

[@therock5853]

Do you have a video o n how to drain and refill an unvented pressurised system please?

[@HammerBlow500]

Very helpful mate. I was bound to do it in the wrong order lol

[@smarsh599]

Excellent video. Very helpful. Thank you.

[@malcolmkenward2663]

Lucky me! There's a valve on the outlet from the tank which just needs closing, plus a speedfit on the vent pipe.

[@duncanvincent9106]

Love your videos… any reason you don’t use a bung on the radiator tails as opposed to the paper you stuff in?

[@hbrowners9754]

Where did you get the bung with the continuous taper from?

[@user-cg1nx1qo8l]

Hi, do I need to clean my loft water tank yearly?

[@freezefoot]

Good,concise and helpful video.Thank you

[@mattspurs25]

Great video Mark however when your bunging the f&e tank and removing excess primary water when swapping out a trv,how much inhibitor would need to be replenished in f&e tank?

[@TonysTechAndCars]

Great video and now I know how to replace the faulty thermostatic valve I have! I would also like to do this with the main water tank feed as the stopcock for it has failed. Is this still possible?

[@gjk291]

The feed should be fed via the cold water main and turning off the main stopcock to the house should stop the flow.

[@d.costacostagliola7298]

Great video mate, appreciated 👍

[@callumhudson5460]

Would this method off bunging work, to replace a seized gate valve, which I need to change before I can move my hot water pipes around in a bathroom refurb?

[@abcenterprises8090]

Now £25 for the two tapered bungs used. Crazy.

[@jeffpop9036]

Really useful information.

[@simonmiddleton4977]

Really helpful, thanks Mark

[@brianp7022]

Hi Mark…I have a gravity fed system with f and e (no obvious overflow on the tank and a new build -as you mentioned there must be some protection at the boiler end so I only have the f and e to block up) . I am considering using this method to change a radiator and install new valves. Luckily I have plastic pipes so I can push them on quick! If I try this could air be drawn in from somewhere else as I have no overflow on the f and e?.. Oh and happy new year! Thanks Brian

[@michaelrodwell4025]

Really useful to see this method thanks!, I changed a 3 way valve recently where I drained the system leaving the mains on...Thick brown water for around ten mins before it cleared, mains off and then I put in inhibitor fluid and refilled. So.... Question is, how do you not leave a customer with a dirty system if you don't drain off the fluid and spot it then? Or would it have been obvious when changing the valve? Thanks

[@michaelsharpin3369]

Could you put an isolation valve on the outlet pipe instead of a bung.

[@michaelsharpin3369]

@Trixie K

[@michaelsharpin3369]

Okay thanks

[@johnmcnamara4846]

Well made video, Mark, thanks.

[@12radiolondon]

Ihave seen two ephenee tanks in a loft, next to each other both plumbed in with open vent on each tank. I suppose they both serve the central heating system, because both were full of water and insulated nicely. Which tank do we plug, in this situation, if I need to replace a radiator valve, please?

[@jonj488]

It's actually "F & E" tank - I also made the same mistake when I first started investigating how to fix my plumbing issues. You'll find the larger tank probably supplies your shower and the smaller tank is for the central heating system

[@malcolmj7670]

Thanks for the excellent video… now I have no excuse do I? What do you call the bungs you use? Is there a special name because I can’t find any on the internet.

[@jonj488]

I struggled too but found them on Amazon under "Radiator Valve Change Kit"

[@natsopa6034]

would this work in a 3 storey town house?

[@ThisOldManOfTheSea]

Is there any reason this method wouldn’t work to replace a seized 2-way Honeywell zone valve? I replaced the head and the new head works electrically from the programmer but it’s impossible to turn the valve (even with pliers when the head is removed) so I guess the rubber ball has disintegrated inside the valve. I don’t really want to drain down an 18 radiator system!

[@plasticbadger1663]

Nice video. Question: could you just turn of the cold water to the F&E tank at the ball valve, let the water level drop by sucking the water out the tank with a wet vac and cap the vent pipe? Is it just to save sucking so much water that you bung the feed pipe? I don’t have a bung (but have a wet vac) and wondered if I could just empty the tank with the water off. Thanks. 👍🏼

[@jonj488]

Yes I believe you could do just that

[@paul_my_plumbs_uk]

👍👍👍 Mark

[@jeffpop9036]

Saved me a cost of a call out
