Lagging Hydra

Buford T Justice

My brother lives in the back of beyond in a small cottage. He has his mains supplied via 1/2" Hydradare and runs overground in places around the house. He has problems of the pipes freezing in the winter and ls left without water.

Is there any point to lagging hydra with something like armaflex, or is it pointless? I think that if the cold is able to penetrate the thickness of hydra, then it'll make short work of armaflex.

Will be digging trenches and putting the hydra down underground, but wondering if its worth doing anything extra with it while I'm at it.

It'll cost a few quid for the armaflex, but if it doesn't work it'll be a waste of money, if you catch my drift.

The armaflex will help without a doubt, if your burying it just go down a decent depth and that will help a lot. For the sake of it i would just buy the armaflex if it saves ya headaches latter on it will be money well spent imo.

Thanks Outkast

Anyone else any suggestions or experience?

You will need to make sure that the joints are glued and water tight or it will be useless.

What glue does one use on Compression fittings? Never come across that before.

Edit: Just realized you were talking about the armaflex and not the pipes - DUH! What is normally used to seal it?

you can get the glue if you want, in my experience its only ok , your better off getting black double width silage tape and use that at any joints to ensure they stick together etc.

No other suggestions really just ensure where the supply is above ground anywhere to be extra careful to tape any joints etc.

Forget about lagging...Just bury it...

If you cannot then lag it but bear in mind you will need to lag it about 6" into the ground...

I can bury the most of it, but where it rises to ground level into the house, is it just worth insulating there?

yes it is defo worth insulating anywhere it rises to house and the pipe rising to these areas.
If your burying deep enough it will do the trick as such you dont need insulation ! but that depth would all be dependant on the area you are in, the soil type , shading etc, if your not burying that deep id go with the insulation for added piece of mind, a few quid spent now will save you worrying later on

Is 700mm the usual dept for sinking water pipes??

Ya i think 700 or 750 is the minimum if i was burying the minimum i would prob feck some lagging on for peace of mind especially where pipe rises to enter builiding or pump house etc , if i went a bit deeper i wouldnt be so worried

Thats good to know. He's getting a machine in to dig some drains fairly soon, so will be sinking the pipes then. Will let him know how deep the trenches for the pipes need to be.

Looks like I'll have to go digging two more footpaths now....:mad::mad::mad:

Exactly what I did,I put my water pipe inside a larger ducting pipe system,buried that into a 700mm deep trench in the ground,and then as the water pipe came up near the surface and then above the surface,it was fully lagged and insulated.

Guess what?

It never once froze over with all the snowy/icey weather we just had.
