- Опубликовано: 29 май 2012
- Part 5 in the series of videos discussing how the water and plumbing systems work within your home. In this video find out how the cold water tank in your home works and also ball valves, overflow and how head pressure is created to supply the pressure for the cold water system.
For the rest of the videos from this play list see: • Domestic Water and Plu... or for more information on domestic water and plumbing please see our how to tutorial projects: www.diydoctor.... and www.diydoctor.... how to tutorial project pages.
We now stock a great range of plumbing tools and products in our brand new DIY Superstore: www.diydoctor....
I'm just trying to get an understanding of the plumbing in my house and this sort of video reminds me why I love the internet, thanks very much.
great very clear video. I would be interested in seeing a video on raising a cold water tank to increase header pressure, and most importantly how to calculate whether the joists need strengthening with spreaders.
Thank you.You really are one of God's Angels Sir!
I'll second that!
Are there considerations (beyond being visible) on where a cistern overflow has to exit, or how it has to run? Mine are currently extremely in the way, and as we're about to do work on bathroom and en suite I'd like to reposition them to make work access easier.
My roof is very shallow pitch (no room to stand upright), and vertical space is very constrained. C/w cistern and c/h header tank are in the middle, totally blocking easy access to one half of the roof space - to get past you have to ease your way past, outside the roof trusses. Both overflows, rather than heading straight to the eaves, run 3 to 4 times that distance along the roof trusses first, making it VERY hard to get beyond the trusses in the first place.
All I can think of is that the overflows fall more slowly as they are than they would if they'd run directly; as they'd normally not have water in them, that doesn't seem a likely reason? They're unlagged plastic.
We've only fairly recently been able to use unvented water systems, hence the system you see, a gravity system.
Do you have a video on how to drain a system like this? We tried to change a valve to a more modern one the other day, after taking the radiator off the wall quite easily, I though I could just remove the valve too. Stupid me! Black water EVEYWHERE all over carpet and walls. I managed to force the old valve back on. So maybe a video on draining the system and changing a valve??? Thanks
This tank has nothing to do with radiators or centralo heating Jadey. This is a cold water tank for the cold water to your taps/bath etc. The centreal heating is on an entirely different system. To get an understanding of how both work go to our website where you can find pages and instruction on draining down both the central heating system www.diydoctor.org.uk/projects/drainch.htm and how to understand the cold and hot water systems in your home www.diydoctor.org.uk/search/search-result.htm?query=water+system&search=1
I have an insolation valve before the ballcock in the cold water tank I'm considering spurring a cold water supply from this as the copper pipe would be minimal to replace if I later wanted to revert back to original. Is there anything I should be made aware of before doing this and the best way to do it.
It's Ok to do this Shaun, it's no different from coming off the cold feed anywhere else in the house. Generally people dont do this because it usually means coming down through the ceilingbwhich can be unsightly.
Amen to this comment!
Cistern...Army uses tanks
That's possibly because we plumb correctly.
i take it that this is not america....you do plumbing really strangely...lol..but interesting though
Tell your doctor that you are heavy breathing during speaking.
You may not realise that you are slightly out of breath.
Thanks for that BraunMannn, I had no idea.
