Any top tips to avoid draining down a hw cylinder in order to

something that I can bung in/over the seat & reduce losses whilst

Or ought else?

TIA


Just turn off the cold water feed into the HW tank - hot water is
drawn
off from the top. Open the tap in question to run off a small
amount of
water (if any), replace washer.


Hmm to clarify, all of those valves are somewhat crusty &
Â*Â* unwilling to operate properly & I fear things could go t1ts up in
Â*Â* a trice....

As the cylinder is only on the floor above I was hoping for a
Â*Â* "limit the spillage" plan rather than a "potentially make tons
Â*Â* more work & inconvenience" plan.

It's not like there's oodles of PSI behind it.... Just need to
Â*Â* control/limit the flow for the 5 mins it takes to swap a
Â*Â* washer....

Have a wet and dry vacuum cleaner to hand, and a change of clothes.

You *might* get away with a bung if you have one the right size.
Another
option would be a second pair of hands: as long as you don't let the
water run hot, the palm or the ball of the thumb will make a seal.

Not if the water is at 60C :-). Turn the immrsion heater and heating
off for few hours, or run away the hot water to waste.


Unlikely to be at 60deg in the pipe, initially....


Remove the top of the tap and whatever is in the tank will soon
increase the temp of your thumb or hand. Been there.

This is why I said DON'T LET IT RUN HOT
