Well done mate, explains it clearly. I'm draining my HWC down to replace the washer on the flow which I had to make as I couldn't buy one anywhere, & it's taking ages so I'll try the siphon, as you suggest, I've finished my coffee break now so, back to it!
Great video. I need to change our kitchen tap but can’t find a gate valve on the hot water supply. I can turn the mains off in the road. Can I simply let the hot run until the tank empties so I can remove and replace the tap?
Hi, Allen great video, I’ve an immersion heater to change......problem is there is no drain off on the cold supply to the cylinder and the gate valve on the hot supply is seized open....🤷🏻♂️🤷🏻♂️ can you help please?
Buy a £10 self priming pump and two pieces of those. I emptied the dregs of my header tanks and tank when removing the system boiler in my house. These wee pumps are fast and they pump a lot of the sludge out.
@@con6951 Laser 2375 Drill Pump. I bought it on Amazon but it now says 12.75 I got it for 9.90 about 4 weeks back. You drive it off a drill. Garden hose fits it. It's a wee gem. It is self priming so no choking on vimto.
Hi mate, thank you so much for the video I really like the way explain things. I just wanted to ask you if you could advise me a leak sealer product Which will seal I tiny leak at the joint cylinder nuts at the body of the cylinder it's could be one of the central heating pipe where enters the tank. Looking to without taking everything off. Thank you so ,👍👍👍
Hello, To get rid of smelly water adding bleach to the immersion heater would your remove heating element pour say half pint of bleach in tank leave for 1 hour then let it out through hot water pipes to taps drain fully and just keep filling up tank and running water till rinsed out would this be OK. I've previously had a shop bought product some sort of small blue and white balls put in system but haven't made any change to the hot water smell. Thanks
Just purchased a flat that has this system the copper tank is empty will it fill from from the gate valve as when i open the main stop tap i can hear the main tank filling from top so will i have to open the gate valve to fill up the copper tank and then turn the switch on to make the tank coil hot thanks.
Hi Allen, thanks for the video! I need to replace a leaky gate valve on the hot water out of my cylinder. Can I stop the water at the mains, drain, replace the tap and then just switch the water main back on? Cheers.
Last cylinder I replaced due to a blown cylinder coil, drain off was non existent so cut a hole in top of tank and dropped a hosepipe straight in and siphoned it out and ran to drain. As was being scrapped hole didn't matter. Also took opportunity to fit a drain valve and replaced the goosed gate valve with new more reliable full bore lever ball valve
Can you just bung f and e and drain remaining heating water from the flow and return from the cyclinder. house has 4 rads above cyclinder. Rather than draining all rads from downstairs. This is when replacing cyclinder
A month ago my my hot water is stopped working but my central heating is working. When hot water stopped working that time there was a trip and electrician said my immersion heater is faulty. I tried to set the time for hot water but still hot water supply does not work. Since then there is no hot water. I am not sure where the fault is. Thermostat? Or divert valve? Or immersion heater ? … any suggestions …
all hot water taps have low pressure, someone suggested one of the outlets could be clogged ( top) due to hard water buildup . shower pump does not work anymore it " cant pump" was going to do this on my own but I think Ill call a professional
Hi Allen I went the job and there aren’t any valve to isolated and the Maine was jammed and had to change cylinder so I just lift bulb valve up to stop water in tank and I pushed cap in outlet storage tank to be able to change cylinder I thought it was right thing I did so I don’t know need your suggestions for next time if I face it again please thanks mate I’m just leaner as I doing my plumbing course 👍🏼💐🙂
@@AllenHart999 no I wasn’t able to turn off it from main is street coz was jammed so had to call to thames water to come and sort it out, I just capped it from inside storage tank (outlet)
Welcome to the world where gate valves snap when you shut them..or when you try to reopen them again. When I was apprenticing I saw a non DZR drain off dissolve when it was touched.....oh boy.
I managed to split the copper tank while trying to remove a failed immersion heater, so I had to replace the tank. The coil was fed by a coal fired back boiler that is now redundant, replaced with a gas fire, so I blanked off the coil feed pipes and tried to drain the back boiler. The water just kept running so it must be connected to the mains, no idea how this can be turned off. Any suggestions - Thanks
"drain off valves are nightmare"... So as everyone knows it, so why there is no better solution as it should have been already, if we have open market?
Hi Allen, Great video. Just a question mate. I recently drained my central heating and my immersion heater started leaking from the top since ? I have gravity fed system with f & e tank in the loft. Your help would be appreciated
Hi Allen, I started watching your videos, because I have problem with my hetaing system/boiler. The problem has been diagnosed as faulty three way valve, which was shorting and blowing fuses. I have old gravity fed system and I am thinking about upgrade. Do you know anyone in the Leicester area, who you would recommend? If you prefer I can contact you via email/watsApp.

Turn main stop tap off and drain tank.

Hello Dave, may I ask where you got the pump From? Many thanks

25 years back I was using a simple drill pump to empty out a cylinder. When your on an hourly wage the customer wants the job done asap!!!

drain offs only stick like that if knobs sweat them up with the rubber still in
Ha great video again Allen it’s better with Vimto
Everything is sticky now lol

Did you use to steal petrol when you were a kid Allen? 😂😂😂⛽
I think I need to do this to change kitchen sink and taps. I can't find an isolation valve.

I’m not keen on vimto...would it still work with umbomgo?? 🤣
They sell in in The Congo.
Paul Stevens if you use Coke you can empty the whole thing just by dropping in a fist full of mentos!
@@spencerwilton5831 diet or full fat?
I rarely use the drain-offs either.
Can’t you just bung the tank in loft, I’ve done it a few times. Works a treat. Only a few quid as well
