I'm having an en-suite redone, part way through, and I've noticed that the plumber has put in mainly flexible (PB) pipes, with push fit (polyplumb) fittings. I was a bit surprised, since I thought normally most of the pipes would be copper with welded joints. So my questions are:

1. Is it okay to use this stuff for long horizontal lengths (about 1.5m)?
2. Is it okay having concealed (and inaccessible) copper -> plastic joints with push-fit (polyplumb)?
3. Is it okay for central heating?

If it's not okay, I want to get it rectified before it's all plastered and tiled over.

Thanks

Bob

Its called modern plumbing. Some love it some hate it. Like many other things in the world, this trade is becoming de skilled. Btw i hate it. Most times it looks like a dog peeing in the snow unless it is properly fixed which it never is, but it can be useful. It does the job.

My entire bathroom was 100% Polyplumb for the last 15 years. I just had it re-done, and had the lot ripped out and replaced with copper. I can't really say why, except that we were having an expensive wooden floor laid and I am an old fogey.

In fairness to Polyplumb, I guess I was being a bit unfair. 15 years is a long time to go without a problem. We did have a problem back in the early days, but that was installer error - forgetting an insert on a cold main.

Having started in industry, I'm one of those copper fans. There are a lot of what we call disparagingly "plastic plumbers" around these days, many of them are builders who think they can do plumbing. Personally I hate it as it looks untidy and suffers from rodent damage. Long term longevity is unknown but I doubt it will last as long as copper without giving problems.

Its good for saving money, easier to install, less fittings, can be fed where copper wont....aslong as its installed correctly I think its ok but there lies the elephant in the room....correctly installed.
 
It won't last as long as copper but i still come across the odd bit of acorn that has been in for over 30 years now.

Depends on the water quality. I've seen copper fail in a couple of years. I prefer copper but regularly use plastic because it speeds the job up and makes my pricing more competitive.

Just finished a job in copper. The customer requested it from the start and cost was not an issue to him. Like what's been said before, alot of people won't pay the extra. I have not had any problems with plastic when its hidden.

Thanks for all the replies. That's reassuring. I was worried no-one did this and it would fail after a couple of years. I don't care about it being ugly because it's behind a wall.

It's great to be able to consult knowledgeable people so quickly when there's a concern...thanks again all!

whos putting it in??
 
I never use plastic in bathrooms. Nightmare waiting to happen once it's all tiled.

I had to rip a chip shop half to bits to find a leaking speedfit tee a few weeks ago. If it had been copper, it wouldn't have fallen off
 
We had a job in st albans about 6 years ago . Mains leak under a tiled kitchen floor . Dug the floor up , found the leak about halve an inch from a soldered joint . All properly done in denso so first thought was they did not wipe off the flux . Replaced the whole floor with new tiles ,job done . Six months later , call back with a leak under new floor. It's a bisson floor so has to reach a saturation point untill it is visable . managed to cut and save the new tiles , dug down and found a new leak on the mains about 10 inch'es from the first one , on a section of untouched pipe , again all rapped in denso so thought it might be red line pipe or similar . Put floor back again job done . A year later leak in the hall way under carpet then one in the loft . Insurance company did'nt want to renew policy so the custards bit the bullet and got us to renew the whole mains , from the stopcock to the ballvalve in plastic . All good ,and after 4 years they are still happy . A year ago there neighbour's had started to have the same leaks so we just replaced the whole mains in plastic . I still dont trust plastic though, but it has its uses .

Hep should b ok as long as tested. Need a tool to get the fitting off so no worries about fittings blowing off although recently ran copper pipe due to bathrooms being plyed, boarded and tiled.
 
O god....h8 plastic. Im more old school. All i use is copper now. Got a new plumber with me, all gas/hetas tickets but can't bend copper. I think same as tamz, trade is bringing un skilled engineers
