Dual pressure tanks?

[DarelS]

Hi all, haven't posted much, but I have learned a lot by lurking.
I have an older pressure tank, 20 gal. I think (maybe 30), which I think is wearing out. It was in the house when we bought it 8 years ago, and I can hear the pump running more than I used to (plus water pressure seems to vary widely). I got a deal on a couple of new 20-gal. tanks (bladder type) a couple weeks ago. Can I set these up in "parallel" to equal one 40-gal. tank? Seems easy enough, but I would like some more experienced input. This is a small house, 1 bath and kitchen, but we want to add another small bath. Thanks so much!

And check the tank bladder pressure.

yep you can do that they don't even have to be close to each other. 20 gallon tanks sure seem small to me I got two 100 gallon in parallel.

Thanks all! The 20-gallon tanks are smaller than I would really like, but I got a great deal. Considering the place is currently operating on one, older, 20-gallon, this can only be an improvement.

[img]/forums/images/icons/smile.gif[/img] I saw a commercially-sold setup once which used EIGHTEEN small cells. It was really clandestine. The problem with so many bladder cells is detecting failed units. [img]/forums/images/icons/crazy.gif[/img] One of my customers had a horse trough at the far end of his barn. The poppet-type valve had no slow-closing ability and when it closed, the water hammer in that long metal pipe shook the whole side of the barn. A small bladder tank at the end of the line took care of that problem. [img]/forums/images/icons/smile.gif[/img]
