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
I fart with the jumper?

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 &
unwilling to operate properly & I fear things could go t1ts up in
a trice....

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

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