I am renting a house in the country that now has rural water supplied. There is a well trol tank that is beginning to leak. Do I still need a well trol tank? Thanks!

No. You can choose another brand, but be sure it is a bladder tank and is not smaller than what you are using now.

If you are on a rural water system, why do you need a pressure tank?

Do I need a well trol tank? If on a pump-yes
If supplied by rural water-No
You may remove the leaky tank. Good luck, Tom
