Heating Oil Tank Installation
I would do it in copper – plastic pipe may be approved (I have no idea if they are or not), but a crushed/cracked plastic pipe will leak all your oil away, whereas a crushed or bent copper pipe will still not leak.
You can get a load of plastic coated 10mm copper pipe for not that much compared to the cleanup costs of a split plastic pipe!Posted 5 years agolarge418Member
But the copper pipe is likely to crack on installation, not when the car/trailer/kids bike etc collides with it. It’s after the installation I would be worried about the pipe cracking. 10mm pipe would be fine throughout, after all, the flow rate is (hopefully) quite low.
Use compression fittings, and you may need some oil resistant tape (it’s like plumbing PTFE tape, but oil resistant)Posted 5 years ago
Ok thanks for the above info, however, will have to bury part of the supply pipe.
Oftec info only says consult with installation team etc, what have they done in your case, I was going to pass copper pipe through hose for additional protection prior to back fillingPosted 5 years agob rMember

The line from our oil tank to house is partial underground (just covered with soil as I found out…), and then attached to the wall.
It looks 10mm copper with a plastic (not sure what) covering.
I’d guess it’s to a specific spec, so just buy whatever is required.

Thanks b r couldn’t find that page of info, will ring local plumbers merchant about the plastic coated piping, however,one of my neighbours recently had there tank replaced and relocated but has been done in standard 10mm copper with screw fitting on every corner- carried out by registered installerPosted 5 years agob rMember
tbh Now I’ve found out that ours (inherited) isn’t shielded in any way and just been covered with earth I’ll be protecting it.
One of our neighbours had a leak (into the wall), they only found out when it started showing through the plaster – big insurance job as not only loads of oil but they needed to dismantle about 10ft of house wall (3ft thick stone job too).
So I’d err on over-build myself.Posted 5 years agoredbenMember
As a plumber I always use plastic coated 10mm copper, its pretty much standard practice for oil lines. ( do not use 15mm pipe as it will bring potentially more problems)
If you are going to use compression fittings then you need brass inserts to stop the pipe from deforming too much when tightening the fitting. (All compression fittings need to be accessible)
For sealing both the threaded tank connection and the compression fittings I would recommend either Heldite or Stag jointing compound.
I work with oil appliances day in and day out and 9 times out of 10 any leaks with regards to pipework are from mechanical damage.
Hope that helps 🙂Posted 5 years agoredbenMember
Erm I would try going to another stockist to get conventional plastic coated copper pipe then, because it will not only be easier to run if its one continuous pipe but also it means the chances of leaking joints in dramatically reduced 🙂
