I found some local places that offer hydro testing but how much will it cost approximately? And what are the chances of my tank failing the test? I'm banking on having my tank pass and not having to buy a new tank
Newer tanks with 5 year cert pass 99% of the time. cost about $25, but most places charge more if you give it to them with the reg on. The test is just like that for scuba tank, physical inspection for cracks or imperfection that will cause a blow out and then it is put under pressure and it must hold for a given period of time.
