Hi

My 86 gal Well-X-Trol WX-302 has sprung a few leaks in the cross T portion between the skirt and the elbow in the center of the tank. I got a price for the WX-302 that I am comfortable with. I did the first install 12 years ago and I'll be doing this install as well.

After a little digging, I was excited to find the WX-302P which has a stainless pipe extending out to the skirt edge. Theoretically, the stainless should outlast the brass cross T in my acidic, turbid water. The only problem is the WX-302P will run me almost twice as much as the straight 302--- $944 vs $519! Ughh!

As an alternative, I was wondering whether a brass cross T with a built-in union might be an equally serviceable set-up. Any experience with them?

How about the sched 80 and sched 120 PVC Ts and manifolds sold on-line?

When comparing tanks, I see the "max acceptance factor" listings. OK---so that is the max drawdown of the tank expresssed as a percentage,etc. The WX-302 has a MAF of .54 while the other tank I'm looking at has a MAF of .41. Why does this matter to me? Does it give an indication of how much flexing the diaphram is doing?

Thanks for any and all input
