Hello all,
Some of you know my history with the Roth Oil tank, but just to refresh. I had one installed 6 years ago which had to be replaced due to poor installation, the new tank is now 2 years old and I have a question that hopefully one of you knowledgeable individuals can answer.
At the very top of the tank is a leak detector that uses some type of expansion material that, when detects oil, will expand, pushing up on the installed rod and causing the mechanical dolls eye to 'pop up' and indicate "ALARM".
Over the last two years I have noticed the 'pop up' to slowly migrate up to the point where I can see a the top band of red, (but no alarm letters yet).
I confirmed all the fittings were secure, no leakage around the threads for the fill and vent lines.
The Roth dealership advised that it is normal to see a bit of red on the indicator over time as fuel oil odours will pass throught the plastic tank and agitate the (expansion material) to a point were it will move the leak indicator by a very small amount.
Is this a load of BS or can oil vapours really travel through solid plastic???
He mentioned the terminology...i think it started with the letter "A" but I cannot remember the process he was referring to.
can anyone shed some light on the physics of this?
Thanks in advance!
