if this tank comes recharged at 20 psi can I add air too it if needed? the watts I have now is recharged at 40 but is bad now

Yes air can be added. There is a valve stem at the bottom of the tank. As I recall, I brought the pressure up to 40 lbs. I checked out their website to see what I use for my well pump switch that runs 40 to 60 lbs.

What is the connection size?

The fitting connection is 3/4" NPT threads.

This tank will be used on an rv, do any of the tank suppliers offer either a wall mount or cradle type floor mount for the heavier tanks? thanks, ray

Hi Ray, I purchased the same expansion tank, and mounted it on my wall. The bracket I used was called Hydro Claw, by storm king. Its not cheap at about $35 to $40, but it is a well made, heavy duty bracket. Very nice looking install. Even my plumber buddies are very impressed! Highly recomend. Good luck, and stay safe. Jeff H.

Rv parks pressure varies. have my incoming pressure set at 40psi. but when using the pump, it comes on at 35psi, & off at 60psi. is this a fit 4 us?

May be helpful, but the pump run pressure range of 15psi is probably normal
