turing of gravity hot water

[Mgrant]

Do most people tend to trust the gate valve on the cold feed to a hot water cylinder will turn off and back on again, when wanting to work on the hot pipework, swapping a bath tap no isos. Or turn the cold mains off and drain all tank.

 

[ShaunCorbs]

I won't trust a gate valve, half the time they don't shut fully anyway

 

[chris watkins]

Gate valves are fine, just don't give them too much stick.

 

[Mgrant]

So you'd drain the tank?

If they don't hold up then you aren't in way worst a situation anyway, still have to turn off main & drain cistern.

If it holds you have saved all that time & 230Litres of water which is why they are required to be fitted under the Water Regulations 1999.

Depends on the quality of the valve.
Pegglers, conex or lever valves ar fine. But the cheapo valves aren't worth fitting.

 

[Last Plumber]

I'd use the gate, it is what it is there for, if it busts or jams it's extra.

If it is a quality valve it should be fine

I don't trust gatevalves on cold & hot supplies. On heating systems they tend to be more reliable as the heating system water doesn't corrode them normally.
I find that even just turning gatevalves off gently and not fully tight off will still often have the gate broken when I go to turn valve on again.
I tend to just bung the tank as it is the same thing as turning a valve off. Obviously I won't leave it like that if I had to leave pipework open, unless I am going to complete the job, - new taps, or tap works etc.

I bet you won't trust using a gatevalve if you are in a rush home, or late for next job?
Could lose you at least half an hour to an hour trying to replace it on a cold tank - and that's if you carry same valve.
The jobs that I have been on that were only to be a couple of minutes to replace a tap washer and I ended up turning into Mr Angry with an awkward gatevalve to replace on a pipe with no movement.

If it jams **** this would be a nightmare

Has happened all the time with me, and water over here is generally good and not always aggressive. The cheap gatevalves seem to be poor brass and poorly made. I replace them with lever valves on cold and hot supplies everywhere.

Normally snap when shut then your fecked get the 12v pump out

 

[SimonG]

If it snaps then I snatch a lever valve on to replace.

I will look at the valve first though and then decide wether to close or drain. Always snaps when you are in a hurry.

 

[Frog67]

If the GV lets by i just stick my "drain easy" plug in the tank connector.

I get the feeling I won't be allowed to forget that. :smile:

Course you will, It still tickles me !

Sorry Best. I'll try and leave it now :smilewinkgrin:

When needing to plug a tank outlet, usually find it is hexagonal or internally ribbed so rubber bung is ineffective. What's needed is a mushroom shaped stopper where stem would locate in hole and dome could be pushed against outlet with length of plastic pipe braced off opposite wall of tank.

Cough..............227 litres lol

I've taken that as verbatum (remember when they made floppy disks) and never actually measured it and i don't know anyone who has. It depends where someone has melted the pipe through the tank
Ruff lol

 

[tamz]

Gate valves are fine if you treat them like a woman. With a gentle touch.
Treat them like a hoor and they will hurt you in the wallet and kick yer nuts while they are there.
We have soft water up her tho

Even if they play up its an easy fix

Must be a "part of the world thing ", I've never seen a tank connection anything but round !

OK tamz, 70/50 gal if thats better for you (227L) imperial boys.

It is 230L in all the books now because the little darlings will find it easer to remember also makes it easy when it comes to single supply cisterns.

 

[Last Plumber]

I don't know why we don't just stick to imperial.

50 gal ........easy peasy to remember.

Why do we mess about.

5 lb lead is still 5lb lead, still made and weighed the same as it always was but now we call it code 5. ....why?

Why are tyres made as 17" diameter and 225mm width ?

And what's all this kw rubbish we use now ?

It's water we're working with not leccy.
It's Btu's . If we changed to metric for that, surely it should have been Calories, that's the closest type !

If youaren't happy with all the changes to how things are measured and labelled, I have one word for you...

whenever I come across these ribbed ones I keep a lump of blutac which I use in a latex type glove to stop the hole

It's true, I wouldn't trust either but it is what it is .. I would definitely turn it off on the gate valve ... it's 50% chance you will be lucky not long ago I wasn't as lucky and it snapped the gate valve luckily I had one to change it as well as a second gate valve was in the loft so wasn't too bad in the end
