Water wells.
I have a 100ft deep drilled well with minimal water flow. The existing pressure tank is WX202 PRO. It has a sophiticated pump control electronics. We run out of water on washing cloth, but do recover after a while,
I have planned to add WX203 P parallel second pressure tank from a local supplier. My questions:
1. How many gallons does the existing WX202 PRO hold?
2.Physical size, pressure and capacity of WX 203P?
3.Is it OK to have the pressu tanks in parallel?
Thanks Valdur Kaunismaa

1. You have a 20 gallon tank. The drawdown on the tank is about 7 gallons.
2. The 203, which is linked below, is a little larger at 34 gallons.
3. You can certainly do the tanks in parallel. I've read that tanks in parallel can have a problem with pressure "bouncing" from one tank to the next. Putting a checkvalve on one of them would solve that.
