OK, here goes again. Lost this thread with our recent glitch so will do my best to restore here. I knew nothing about bead filters until I started researching for this project. Thanks to Garrett (harveythekoi) who helped me with much of this and his idea got me started. Here is Garrett's original post of his idea for a lower head bead filter. The second post shows the schematics of mine. End result the venting changed just a little as will be seen in the final pics.
EDIT: After a couple PMs from others about building one of these...following is a 95% parts list....best I can do from memory and looking at picture:
I'll start with the stuff I had to order.
-1 stick(5') 3" .040 well screen from AES
-2 bags of beads from AES (garrett is using the doll beads)
-(3) 3" Uniseals
-(4) 1" Uniseals
The rest came from Lowes/plumbing supply:
-(5) 2" ball valves
-(4) 1" Tees
-1" cross
-2" spring check valve
-2" flapper check valve for water inlet line
-(3) 2" Tees
-(3) 3"X2" reducers
-3" rubber cap
-2" MIPT thread adapter
-some kind of screen to keep beads in on vent (I used bottom of a plant basket)
-3" end cap
-(2) 3" couplings
-3" 90 fitting
-3"X2" bushing
-2" 90 fitting
-(2) 2" 45 fittings
-(2) 2"x1" bushings
-
Of course, 1",2", and 3" pipe and Blower.
EDIT: With higher flows 4" well screen and waste outlet and associated fittings/pipe should be used. Anywhere a 3" item is listed above it should be substituted with a 4" item. It is important to carry the waste outlet out and down to ground level in the same size as the well screen that is used.
