Poly V Copper Plumbing

[pedruid]

We are renovating a cottage we own in a retirement complex and have has the old bathroom gutted. The plumber has installed new Poly (with some sort of mesh reinforcement) which has been rejected by the Estates manager who insists it must be copper.
Can anyone supply me with information that I can use to fight his decision. I did not ask, nor was I told what type of plumbing materials should be used.

The regulations you are looking for are covered in SANS 1315. Will see if I can find a link to a copy.

Slightly off topicersonally, I had to change from grade 1 copper pipes to poly copper as they were getting eaten up. Apparently, I have acidic soil.

Thanks for the link but can't afford R346 for a copy.

Go copper. Problem with Polycop is the connex fittings tend to get overtightened which eventually results in the olive ( compression ring) to sheer through the pipe. Never trust the stuff inside walls, good for underground.

Ask him what right he has to tell you what to do inside your private property.
He has zero say about the inside. And if it's all done according to the standards no one else can force you to change it either.

Do make sure you properly pressure test the piping before plastering over it though.

Think you should be looking for SANS 10252 now, not SANS 1315

And those allow for "plastic piping" so long as it meets the requirements of the listed standards.

im not surprised that some people do not stick to the standards when you have to pay for a copy of it..

Hi all, thanks for your comments, however I have checked the piping and its Textite Metal Flexible tubing and is widely used in the Uk.
It's been installed internally and externally and it's the external use that the complaint is about and that he wants replaced.

Ahhh ok then you may have an issue since it's a complex and they will have visual guidelinee that have to be adhered to

I would strongly advise against this. I have 'Ginde' installed in my home which is exactly the same PEX-AL-HDPE or PEX-AL-PEX piping - just with a different fitting design - see my thread here:

So I have to say it's not a bad system. It's quick and easy to install and if the fittings are joined correctly you will have little to no issues. The real problem is that most plumbers:

1.) Have no idea how to work with it.
2.) They also don't have the specialized crimps and reaming tools to work with it.
3.) Don't import the fittings.

Think about what is going to happen in 20 yrs time when you can no longer get the fittings you want. In my case I ended buying the crimping tools at a gas supplier (they use a similar system) and managed to source old stock of fittings from a Plumlink warehouse in the Eastern Cape. You don't want that nightmare. Trust me.
