  Had 3 ST-5 expansion tank from Amtrol. All 3 died under a few years. The last one I got didn't even last long enough for me to mount it on. There is something serious wrong with these product. These are rated for 150 PSI but it can't even handle 80 PSI. These suppose to have 5 or 7 year warranty on them. But they make it so difficult for you to claim it that its not even worth the trouble. I call their warranty line multiple times (****), no one picks up with a VM to leave massage but it just hangs up. Tell is that a company you want to buy from. I took my business to that orange band store, product was at half the price and the diaphragm is designed correctly.

  We moved into our home in 2013 and immediately replaced the boiler on 6/16/13 which included a corresponding water heater - a Amtrol Boilermate water heater. After four years, the first water heater was leaking from the connection ports at the bottom. The water heater was replaced 7/27/17 under warranty - I had to pay for labor. Four years later the replacement water heater leaks from the same location as the first. After several emails to Amtrol and my local plumber, I was able to have the water heater replaced 4/1/21 under warranty - again I had to pay for labor. This new water heater is designed differently than the prior two with the connection ports moved to the top of the tank - presumably due to defects in the old design. The new water heater, however, has already begun to leak two years later. It is now 9/5/23 and I have scheduled an appointment for the plumber to inspect the problem - again. This will make for three Amtrol Boilermate water heaters replaced over the past ten years. This is completely unacceptable for a unit that retails for $1,800. I will never use another Amtrol product again and I do not recommend their products at all.

  There are other reasons why a product can fail that do not relate to manufacturer defect, such as excessive incoming supply pressure, aggressive water, or improper installation. 
  
  The Manual and label on the tank clearly warn do not locate in an area where leaking or flooding could cause damage to the surrounding area. Most local plumbing codes require that a drain and/or drip pan be installed to mitigate any water damage. There is no evidence provided that a drain or a drip pan was installed to avoid damage.  The label on the unit as well as the warning in the Manual warns Failure to follow the instructions in the accompanying manual can cause a rupture or explosion; causing serious or fatal injury, leaking or flooding and/or property damage.
  
  The Manual also warns to Determine whether your water is corrosive or acidic, and that there are no suspended solids,toxic or other substances or abnormally high chlorine levels in the water that could damage or affect the water heater or the rest of your plumbing system.
  
  The Manual additionally warns that appliance should be in an area where water leakage from the tank or connections will not result in damage to areas adjacent to the appliance or to lower floors of the structure.  When such a location cannot be avoided, a suitable drain pan must be installed under the appliance. The pan must be connected to a drain.
  

  If the unit had failed and/or was exposed to over-pressurization, the temperature and relief valve (T&P) would have been discharging giving the property owner an indication there was a problem in the system. Periodic inspection of the unit, as recommended in the Installation and Operation Manual (Manual) could have detected any problems and the unit could have been replaced prior to catastrophic failure.
