Is it okay to plumb whole room with polyplumb?

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 .

plastic is best installed in bathrooms with out fittings hidden we tend to form a manifold below the bath and run out in unbroken lengths to each item

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

the magic words are "if installed correctly". as with most things if installed well it will last well. all ill say is clips, clips and clips.

If I have to use plastic under floors I tend to join it using regular compression fittings.

On the moors where people have private water supplies fed from springs, I do all plastic as the water is very agressive and copper rots away rapidly. Water cyinders have to be stainless.

How long should something be likely to last before it can be said to last long enough?

Until it no longer belongs to you

the pipework should last longer than the thing its piped to.

 

[TBServices]

Both very valid points.

If I'm piping something up, I take the attitude that it should last forever under normal conditions.

when I started on my own was within a year of when my granddad retired and I still have customers on my books where I replaced like for like bathroom ect that he piped 30/40 years ago you may need the od imp to metric converter but I am more confident with his 30/40 year old installs than I am of plastic but that's just me!

Use whatever material is going to last better & with no risks if possible.
If the water isn't corrosive to copper, then use copper for plumbing & always copper for heating.
There is no real saving in cost for a bathroom to be done in plastic surely, - unless a lot of time was saved?
The plastic pipe will save very little, the plastic fittings will cost more, then you need inserts plus clips. As to plastic needing less fittings - usually I notice every bend done in plastic has to have a 90 degree push fit & instead of an offset (like on copper) guys need two push fit bends!
A good plumber can install copper fairly quick & the soldering will add time - but 10 soldered joints in a bathroom ain't going to take too long?

in a bathroom I 1st fix install all pipework clips then pipe it fluxing all fittings as I go so everything terminates into a full bore iso then solder everything in one go I don't think it takes anylonger as if your using talon clips you need to add spacers for speedfit if the are ran in parallel i and it looks nicer in copper but each to there own I guess

 

[village idiot]

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.

I hate the stuff to extreme. The only time I use it is if one of my colleagues (with whom we normally share big project jobs) calls me to help him with a Central Heating Installation and ofcourse, he is fitting with push fit 'rubbish'.
