Testing for leaks in oil line

[tamz]

Should drop that much maybe .5bar max over 24 hours

Don't be daft

Hello again - OP here.

The engineer felt that the leak had been due to the PVC fittings that had been previously used and replaced them with brass (getting on for two months ago now.)

I noticed a bit of a smell near where the pipe enters the house today and found that the pipe was indeed wet with oil. I wiped it dry but a couple of hours later it was coated again.

The pictures below were taken after I had again wiped the pipe off and then again after about 20 minutes - you can see the darker area where the oil is leaking.

So what do I do? I'm loathe to call the same guy out again as I'm not sure that he knows (or cares) what he's doing.

My questions are:

1) can anyone recommend an engineer in Rossendale/Lancashire/West Yorks who can come and sort this out/reassure me that all is well
2) am I just being naive - should I expect a small amount of leakage on a warm day?
3) does the set-up in the pictures look right: the exposed green line, what I assume is a disconnected fire-valve etc...

Don't do oil but why has the fire valve been removed ?

It was like that when we moved in and was left like that on the two occasions when the boiler was serviced, including the occasion above when the oil line was pressure tested.

I would be concerned that the fire valve is disconnected, that needs immediate attention and refitted or replaced if faulty, the weeping oil line needs sealed using a pipe insert, ptfe and fuel seal for example haldite. You can use a vacuum gauge on the oil pump it can indicate problems with an oil line.

It isn't against the regs to use plenty of pipe to fitting joints, but not good practice. Minimum joints, minimum possible leaking points.
A remote firevalve needs refitted (that one lying on ground might be faulty and no doubt full of water and dirt now).
I would prefer a male fitting into each side of the firevalve (a male straight and a male bend) so that you only have 2 pipe connections there.

as above, is your guy OFTEC registered, any engineer will know that fire valve should be fitted or in this case, replaced.

Thanks for the replies - anyone got any local recommendations for me?
