Help Weeping hot water pipe

[Otter Spotter]

I have found this hot water pipe under kitchen sink weeps when pump pressured up. It gets worse when the water is hot!
I have tried to retighten the circlip and the black tape is to stop any movement of pipe when travelling but to no avail.

Should I use PTFE tape or is there something else I can do to stop the leak?

Strangely the cold water joint which looks less secure does not leak

Take the pipe off cut off an inch and rejoin preferable with a new clip.

 

[David and Sally]

One option if you have slack in the pipes. Cut off the hot pipe where the spigot has been and refit spigot to a ‘fresh’ section of the pipe. Only needs to be about an inch.

Edit…My fingers slower than Lennies

We had a similar leak on a cold water T piece.

Tried different size jubilee clips to no avail.

Ended up using PTFE tape as the joint was so loose.

Worked a treat

If you can, take an inch off the hose, new jubilee clip and make sure it's far enough down the hose. Looking at your picture, the jubilee clip on the cold is much further to the right. That may mean the one on the hot is not biting where the grips are on the core.

Way too slow typing. At least we are all consistent.

Cheers guys will give the cut 1 inch off and refit a go, but be warned I may be coming back to ask “ How do I get a new Red pipe fitted to my van“ because I have cut it wrong

If there's no slack in the pipe undo the jubilee clip and turn it around the pipe as much as possible.
Warm the pipe with hot rags then tighten the jubilee clip.
PTFE tape won't seal it, its intended purpose is to seal threads.

Why not try ptfe tape first ?

Agreed on that.
Try moving the clip further to the right....as on the blue pipe

I find jubilee clips are not the best on small diameter pipes, as they tend to distort the 'round' profile. I find the spring clips better. Also they are self tightening, so as the pie expands and contracts the grip tighter.

Looking at the photo, I think it an old bodge. The hoses to the left are tap tails that have 'o' ring seals and are designed to push into the tap base. They are not, in my opinion suitable for joining straight onto 12mm plastic pipe. However a seal could probably be obtained using the suggestions above. One other thing I would do, is dip the newly cut end of the red pipe in boiling water prior to fitting, clamp it and let it cool.

Trouble is Dave is short enough, the poor wee chap.

It looks like the cold water feed has a purpose made coupling which probably terminates with a serrated end (possibly John Guest pushfit connector).

If you disassemble the hot water connection, you'll probably find a smooth spigot (where currently the red hose is connected). Hence the leak.

If it has a smooth 12mm dia spigot, you could insert a straight JG coupling + JG serrated adapter, as shown here:

Which end have you been looking at Hazel, Dee isn’t complaining

Well fortunately for me I have only seen you with your clothes on, but if your not sure which bit is on the short side that says it all really......poor Dee, she is a saint.

Thanks I will have a look.

If all else fails try self amalgamating tape from Screwfix, catalogue number 2115v. You stretch it as you wrap it round the male spigot, it forms a really good slightly sticky surface that your red pipe will adhere to. I’ve used this on rubber heater pipes in my ancient Morris Minor and it’s held the pipe together for nearly 6 years!

Cheers!

The rest of it's fallen apart but the heater hoses are still as good as new

I won't say what Robert just said to that.
In the meantime I'll search for a really good microscope.
