Advice Please - Disconnected toilet, what 15mm cap end do i need?

[bilabonic]

The taps are now working fine, jump jumpers/seals.

I am only getting a slow trickle on the HW upstairs, downstairs is kitchen sink tap/flow is fine (bigger head height)

The head height from bath/basin upstairs to tank (not even in the attack/ 3/4 way up in a cupboard) is only 6ft if that tbh.

No valves are off, it's just the upstairs taps had seized as in pics due to no use for probably years....

When i open a either tap it gives a good 'spurt' then goes to a pathetic trickle.

I was thinking an airlock and was going to try old trick of pumping mains from mains CW from basin into gravity HW on the basin but it will not fit over tap ends.

If an airlock, the old hose trick should work even if you don't have a good seal. You can use tape or even just your hands as a seal.

But first I'd try to run the tap with the mechanism removed entirely, just to rule out issues with the tap itself. 6' head should give a reasonable flow with those taps, even if it will never be amazing.

With a tap OPEN, you could also try a hose from the ballcock in your cylinder feed cistern to the cistern outlet. Being careful not to overpressurise the cylinder.

Yes, i tried that, i removed the cartridges/jumpers completely and it was still a trickle.

I know the main tank has run CW tank/cistern has run empty, i looked into several weeks ago when i viewed the property, it was barely on the feed line so mains water had been off foe so long.

I have just been given a length of 15mm ID koi aquarium hose from a neighbour with should fit snugly between the basin taps.

What is the process when i attach it?

Fully open the HW tap, then slowly open the CW mains tap? How long do i run it for??
I presume until it feeds all the way back down to downstairs cylinder then back into cistern?

Shall i get a friend with me to watch the cistern for air bubbles/water level even though there's an overflow in it.

Thanks for replying.

10-20 seconds then pull the hose off the hot tap with it fully open

I was just thinking with regards this old type floating valve insert, when i open the hw tap, unless the valve 'lifts' a little then pumping mains into it will most probably cause it to close shut?

The tap end /spout leads to the closed side of the valve unless it's lifted, it is not manually lifted via rotating the threaded internal screw (opening tap).

This type of tap does not allow 'backflow', it's like a check valve/one direction!

Trying to put mains into it is pointless surely....

 

[bilabonic]

Am i correct here guys, the CW mains will just close the HW tap insert/lifter, surely i will need to remove the inset/lifter for it too work?

Anyone confirm please??

Thanks

You're right!

Yes, I think you are right. Could get messy!

I think, if he removes the jumper and gets the flow going, he can then dismantle and reassemble correctly with the system 'live'. A 6ft head is not going to be that difficult to control even with a tap dissassembled.

 

[bilabonic]

There is an old gate type isolator near the HW tap, i'm hoping i can remove insert and reassemble, get flow going hopefully, isolate, then reassemble, reopen valve.
Otherwise it will be messy. lol

Cheers guys.

Could always 'fix' the jumper did hundreds as a apprentice!
Two hammers end of jumper rested on one hit end of jumper with other hammer turn it slightly oval will hold it up stem of tap.

 

[bilabonic]

Why would i want to damage the jumper to keep it open?
It's easier to simply remove it surely?

Anyway guys little update, i did not have to do anything to the system? The pressure was fine??

The only thing i did do yesterday before i left was put the HW/boiler on constant.....

Has the expanding water simply increased the pressure? Or has the presumed airlock simply freed itself??

Anyone got any views on this? I will turn it off tomorrow and test it again the following day.

Cheers

Seeing as the OP didn't like the loose jumper, this was good advice. The OP didn't appreciate it, but I think you were helpful, thanks.

Ah, sorry i was confused by your response tbh, so by hammering/flattening the the 'pins' on the jumpers, then placing them forcefully back in the threaded part it was cause them to effectively jam and lift up and down when screwed.
Great idea tbh, sorry i misunderstood.

Plus MANY thanks to everyone who helped with the problem, great advice as usual and it IS much appreciated!!!!
