Details on fitting a remote oil delivery pipe.

[DevsAd]

Thanks SJB - I'll do that.

We had one delivery pipe installer out to have a look at running the pipe on the other side, against the cottage's wall but essentially on the neighbour's side - and they'd obviously need to give permission for this.

One thing that confused me when he reported back (unfortunately I wasn't in when he called, so this is second-hand info): The remote pipe would be run against - and attached to - the cottage's LH wall until it got past the rear extension, at which point it could come on to the cottage's land and make its way across to the oil tank (see amazing diagram). An issue is that the patio shown - recent, and nice natural stone - would need taking up. When asked why the pipe couldn't go beyond the patio (a further 2 to 3m) until it reached the lawn before cutting across (which would be much easier to trench and make good) he replied that he couldn't because 'he isn't allowed to use elbows'. I wasn't there to ask how the pipe manages to turn a right angle to go under the patio without an elbow.

Could anyone explain, please? Is it to do with the underground pipe being plastic and, for some reason, no elbows are permitted?

Is it ok for the pipe to begin as steel and then become plastic for the underground bits?

Thanks again.

Plastic pipe is OK for subterraneal pipe work supplying a boiler but andextended fill line must be 2 inch steel, so my understanding is.
Honestly I am not currently OFTEC, so am not fully up to date on this particular situation requirements.
As I said above give OFTEC a call and they can go through everything with you, if needed make a list of points to cover beforehand so you don't forget something.
I personally have never had a customer with an extended fill line but have a number of associates dotted around the country who have and one image I was shown yesterday of a compliant install DID have 90° elbows, so I would take the word of OFTEC before the guy who supplied you with that information.

Thank you.

I'll run it past OFTEC.

(And come back with my findings...)

From memory its 2 inch, with an NRV at fill end with cap and a drip tray and an overfill alarm of a certain class. My associates haven't got back to me yet but I will update when I have the current requirements

Current OFTEC books state that if a fill line must be used it must have.
. 2 inch (50mm) diameter black steel or equivalent fill pipe terminating with a 2 inch male BSPP (British Standard Parallel Pipe) thread hose coupling connection and non ferrous screw cap and chain.
.Isolation valve after screw cap.
.Non return valve.
.Drip tray under screw cap.
.A suitable overfill alarm.

I have done precisely one of these to those specs. Our regs on oil are very strict and follow OFTEC guidelines and some local ordinances that go above and beyond as the whole island is classed as a water catchment area.

No galvanised steel is one reg also in the OFTEC books too, just in case anyone was tempted to use that.

The "Not allowed to use elbows" is probably a miscommunication because You quite simply have to use elbows, unless you want to go all medieval and start heat bending 2" steel, something I only ever did at college. In most situations, sometimes quite a few elbows are required depending upon the route. Unless something has changed I don't think changing direction with elbows is a problem but rather a necessity.

Thanks, Stig - that's useful confirmation.

I'd assumed it was a misunderstanding by the person who'd taken the message.

We will arrange another viewing of the property and take along a different OFTEC person to advise on all the possibilities.

Cheers.

Also, with regard to drilling through the property, I was the diamond drilling guy for the last company I worked at. I could drill a hole up to 8" in diameter through any common building material to a depth of 5 feet and could go longer with another extension piece. I regularly drilled through walls made of granite stones, sometimes to several feet in depth. The hole can be drilled and the remote line can be fitted by the right people. Oil lines can be run through domestic properties. Sleeving requirements must be met but it has been a while since I did such work so cannot advise on the current regulations but there will be a way to do it.

Cheers, Stig - thanks for the reassurance.

I have had a local drilling company confirm they can sort the 'hole' part of the job. I'm guessing it wouldn't have to be more than 3" diameter, and sleeved?

I'll report back once we've had a further viewing with the new OFTEC fellow.
