This replaced the Wellmate tank installed 20 years ago when I built the house. The bladder went bad on that one and couldn't be replaced easily as this one's can.

New tank leaks straight out of bottom of tank. And good luck trying to buy replacement parts to repair the tank. The wellmate company will not sell to individuals. And vendors don’t carry single parts you can’t even find replacement o-rings.

More than double the capacity of the old 19 gallon it replaced . Deep well Pump does not have to cycle as much - about half . Big tank holds pressure longer time , great for showers .

The shippment was super fast and it arrived as discribe. The box where the pressure tank is shipped in was strong so no dammage to the tank. The 47 gallon is perfect for a house for 2-4 persons. I had to change my old tank because it was a metal one that rusted (I live less than 150 feet from the ocean) so the fiberglass is perfect, wont rust. The previous tank was smaller and the pump was going on and off more often. Because the 47 gallon tank is bigger the pump runs longer but less often. Better when you go for a leak in the middle of the night and you don't want to wake everybody up! Just a bit disapointed in the black plastic stand that looks a bit weak. Good combination with the "STA-Rite SND-L Shallow Well Jet Pump 3/4HP" The input/output is a 1'1/4 male NPT and the tank pressure is set up at 20 PSI. Would recommend.

So far happy and installation no problem and seems to be a good deal.The only thing that gets my attention is I could have purchased this identical item on E-Bay for approximately $60 less the only reason I did not send it back and do so was I needed it now that’s it live and learn.
