I'm sure it is 'well defined' someplace in the sales literature, but since most of us live in the real world, it makes absolutely no sense at all. i have from 47 to 120 gallon xtrols, and there is no logic when you look at a tank that says 47 gallons and your mind pictures a tank the size of a 55 gallon barrel......and you say 'NO F......Way! The 120's are even more dramatic...... If you shut down a 120 gallon tank, you'd be hard pressed to get 30 gallons out of the pressure bladder side of the thing.

Thought you'd luv to hear more confusion about 'equivalent storage'. :shock: :shock: :shock: :shock: :idea:



I am learning a lot, your right the tank only holds about 1/4 of the rated size.

Lets see if I can shed some light on this :idea: . A 2wire 220 volt pump has 2 hot legs and a ground, the capacitor and relay are built into the pump. A 3 wire 220 volt pump has the capacitor and relay in a box normally on the wall by the tank. Tank sizing and equivalents, I'll have to get in to after work. :)

Many well drillers/installers here like the two wire submersible pumps, and usually install a 30 gallon or so bladder tank. ONLY if you jump up and down will they go to a bigger storage tanks. Obviously those of us who install our own, create a manifold and add as many as we like...or as many as the well will support.

The equivalent size thing refers to back when we used tanks without air bladders. Back then you might have had a true 40 gallon tank but when filled properly with air you only got about 7 gallons of water out of it before the pump kicked on.So a well-x-trol wx202 tank is probably "equivalent" to the old 40 gallon non-captive tank. By making the tanks a captive air tank (bladder) they could shrink the size of the tank without the fear of losing the air. Note that the higher the working pressure of the system the less water in the tank. Whistlenut pulled up a link to a x-trol site that should have a sizing chart. :)

Hmm, I bought a Well X trol 350 (120 gall) with my brand new 3/4HP Gould pump. We have a horse farm with 20 horses, house and ring watering systems etc. It took me 2 years to burn out the pump relay work out the POS was defective from the factory (yes I know how to set pressures). Thank God Gould makes a great product. So my acceptance factors are to use big galv tanks without bladders that have a very short half life and made of steel with the same rusting potential as a Jeep Liberty. No Well X trol tanks or GM cars for me EVER again. I may not have the memory of an elephant but when I do REAL stupid things I try to 'get it'.

The 'rents have a fiberglass pressure tank and Acid neturalizer tank...
All plastic pipe...
I'll grab a pic of it later...
The old tanks were galv with no bladder...
Upgraded to a metal bladder tank but it just rusted out...

Question please, I have this 1 1/4 inch well tee. I would like to put a union in to get me to one inch copper. What can I use? Will a dielectric union work or will that not mix with brass?

thanks

I'd go with a cast bronze bell reducer 1.25*1 nipple and bronze union if you feel the union is 100% necessary.
You can lay your empty tank on its side and build your manifold without unions. Maybe use a sweat coupling on the 1".
