We have a stainless steel hot water cylinder pressurised system that has now had the cylinder fail 3 times, each time just a few weeks apart. The manufacture says it must be our water (from our well) that is attacking the stainless steel cylinders, we have had the water tested and nothing apart from high manganese content was found.

Does anyone have any ideas why these tanks could be failing, we are due to have the fourth tank fitted in a couple of days, Iam really worried that it will just fail again.

Could it be a Galvanic corrosion problem? the s/steel cylinder is connected via brass compressing joints to copper pipes for the central heating and water feeds bathrooms, kitchen etc.

or could it be faulty tanks and the manufacturer is reluctant to accept blame there fore blaming the water.

The manufacturer tells me they use LDX2101 stainless steel, is this a quality type?

any ideas anyone?
thanks
