cylinder leaking

hi please can you advise regarding the cylinder leaking on my pulsacoil 2000. I am supposed to be covered on our block building insurance but the insurance company are saying that the cylinder leaking on a 7 year old system is fair wear & tare. In your opinion does this seem acceptable that a 7 year old system should fail completely?

Thanks for your help.

This is a common problem with Pulsacoils and most Gledhill thermal stores. It is my opinion that they should last a lost longer than this and many do, but the fact remains that many fail.

Not sure what difference you expect my opinion to make to your insurance company!

Cheers, Mike

Hi Mike

Thanks for that, not going to make a difference to my insurance company but gives me an idea if it is worth pursuing!

Do you think that it would be worth trying an additive such as Firnox Leak Sealer to a leaking cylinder? If so what would you recommend - simply add to header, or drain down first?
