plastic pipe

Hi, Im Marie, Im not actually a plumber. Im a draughtsman, but I help out in production 50% of the time too... It helps to make sense of what I'm drawing! Our company work with aquatherm and make a product similar to a domestic boiler. Anyone else regularly working with this stuff?

Hi I replaced our leaking bathroom tap yesterday, it’s one of these mono mixer types. The existing one had 2 copper connectors which then were connected to the plastic water pipes via plastic pushfit fittings. As the new tap had flexible connectors with a nut on the end I had to change the...

Hi, I've used plastic pipe and standard metal flexihoses to connect water to tape and toilet, and both of them leak! What am i doing wrong? I've followed the speedfit recommended instructions , using copper olives, standard pipe inserts and even ptfe tape. Do people find this method...

I came across one of these fittings last week, that had popped under the bath...

Hi Guys Hoping someone can help. Came across a house in Devon completely plumbed with glued 15mm PVC type hard plastic pipe. (The lady wanted a basin replacing) The tap connectors were brass/copper imbedded in a plastic pipe connector, the pipe and fittings are white, with '15mm made in uk'...

I have froze pipes with aerosol pipe freezers many times, I now have at my disposal a Rothenburger Rofrost electric freezer, supplied by my company, great bit of kit, only problem is I have tried to freeze Hep20 twice and there is a lot of this in the building I work in, I have so far been...

I have to move a hot water storage cylinder to a new location. The new location is somewhat further from the boiler and the route is trickier. To that end I have considered using 22mm plastic pipe for the flow and return, it should have less thermal loss and be considerably easier to route...

What brand pushfit do you use for install for central heating system hepworth hep2o ....john guest ?

A quick question on secondary returns for HW. I remember reading somewhere that you cannot use Hep2o for a secondary return. Could someone explain why? I was thinking about this the other day, and central heating circuits are fine with Hep2o, so why not HW circuits? Surely both pump hot water...

Anybody know where I can get one of these from for working on plastic pipe without freeing or draining down.cheers in advance

I'm after a little advice; I'm changing a radiator and need to extend a plastic pipe that is mounted behind dot and dab plasterboard. I don't really fancy channeling out all the pipe back to the joint; but I haven't been able to find any reference on the internet about jointing "in-wall" and...

Hi All, I am DIY'er planning to lay my F&R as a 22mm copper "trunk" which will then drop down to feed individual radiators. I would like to drop down (in wall chase) with 15mm copper which present themselves behind the rads and then connect flexible plastic pipe (15 or 10mm) which attaches to...

Hi all, think this might be a stupid question but, I have just used plastic and speedfit to a new radiator am i right in thinking no bonding is needed to that rad ? Thanks for any replies and looking.

I have been doing plumbing and heating for 11 years since leaving school and this week I came across this pipe for the first time and severely struggled to find anyone who knew what i was on about when ringing around for a fitting. If you are unaware of the pipe its a dark grey colour and...

Went to an emergency callout tonight. Water marks on the ground floor ceiling. Drilled a few inspection holes and found this! A mouse had taken a chomp out of the 10mm microbore pipework supplying the basin upstairs. Mains pressure pipe and all! Luckily for the homeowner it was only really...

Hello all, Quick confirmation question! I am currently getting quotes for central heating, looking to do most of the work myself to save money. My current system is 20 years old, with an old Ideal Elan 2 boiler, and a "Mainsflow" hot water cylinder. I've had some issues in the past with...

Anyone know why the water in this stuff gets so much iron oxide inside? Drained a heating system this week plastic pipe all over the house and its black as hell full of rust and bits of sediment . Use to see this a lot on new builds as well all barrier pipe used but still goes to pot inside...

I've come across a few jobs over the years where houses have been piped in hep class H Single wall plastic pipe (not barrier) the pipe work seems to encourage corrosion in the system and rapidly blocks up the circs, no matter what size of pipe. have any of you experienced lads/ladies come...

Hi The Knowleageable I dont do plastic plumbing, i'm old school copper BUT just got a flat for my son. Just had to rip up the kitchen floor due to a leaking waste pipe. all plumbed in plastic, no pipe clips to speak of so now installed some on the water supply to sink etc and fitted a couple...
