How to repair pond pump cable?

[Nozzle]

Some kind of resin-filled solution? As would be used for HV cables underground

Ah - the perils of not reading all the replies before replying oneself.

Ah, the perils of being a bell end.

Oh - I wouldn't say that you were that - you're being too hard on yourself.

One of them WISKA Shark joints will suit you, sir!

Does the gel make that choc-bloc maintenance free then?

Why would it need to be MF? It's a joint in a flexible cable.

There seems to be a fair of lily-gilding going on.

Quite honestly, if the joint is not to be buried I think that Robin's suggestion

is all that's needed.

 

[chappers]

They're not perfect, there is no perfect solution if the whole cable can't be replaced, but they are adequate provided you ensure the joint doesn't end up lying in a puddle for a long period. If that occurs, the joint will eventually suck in water as the air pressure inside it changes with temperature.

I thought IP68 was suitable for permanent submersion

 

[Taylortwocities]

That may be, but its not even going to be submerged!

The connection will be outdoors, but not under water.

Paul Uszak also said that he was suspicious that these devices can adequately seal a 7mm diameter cable. That's right at the bottom of the acceptable range. I've had the same issue with those compression glands that you use to go through a boxes' sidewall. They never seem to close down an any type of cable that a normal DIYer might use. I don't want to set my pond on fire...

 

[PaulUszak]

PS. Why does the pump cable have an earth core? The pump unit is all plastic, looking like double insulation and the pond itself is truly in the earth. It should really need any more earthing should it? Protect the carp?

 

[EFLImpudence]

Solder and adhesive heat shrink ?

I don't want to set my pond on fire...

Keep a bucket of water nearby just in case.

Protect the carp?

Don't forget to bond them.

I didn't say it had to be, I just asked if it was! Actually, even if it was wired in via an RCD FCU rather than a plug, and therefore part of the fixed installation, it doesn't matter as it's an encapsulated joint which therefore doesn't need to be accessible (526.3-ii). I'd forgotten about that.

Here is one of my threads of old (not talking a medieval garment):

Either this or one of these:

With it having cable grips rather than a stuffing gland, the cable diameter is not an issue.
