If you are having trouble finding the parts I could make on for you , no big deal . What valve do you want to use ?If you have compresed air I would go with a air powered valve , they open alot faster . Ive seen your tank in person and would say a few three or 4 inch valves would get things moving nice . A 4 inch valve mounted on a 150 gallon poly tank would work so nice on your system .

Bill,
When did you see the tank?
I now have a 300 gallon CSD on the tank with a 3" siphon line, so it takes 5 minutes to fill and 1 minute to dump.
I was recently considering switching it to a 4" pipe for an even greater surge but am now considering changing out the siphon to eliminate the bubbles. The CSD is elevated above the tank, so my thoughts are to stay with the 3" pipe and Asahi electric actuated valve as a 3" valve is relatively much cheaper then a 4"valve.

I may take you up on the offer of help. So the way you have it set up is the valve closes at a set time interval based on how fast the chamber drains. Any reason you did this vs. putting in another float switch just above the bottom of the siphon pipe, so the valve would close just before pulling in air?

Sanjay, see you this Sunday at Pratt, yes?
Thanks.
Joe

I didnt go with the float valve on th ebottom because Iam not a big fan of float valves . They always fail , The on on th etop has a pingpong ball glued to it incas it get stuck to give it some extra boayancy . I also use a overflow pipe oncase it sticks . The timer is as close to fullproof as I can get and has never failed in years , Plus it also give you the ability to adajust the how much water comes out of the tank , You can set it to dump it all or just half or whatever you like .I agree that 3 inch valves are alot cheaper than 4 inch . I think three inch should work good for your system . Iam working on a dual valve setup right now where on tank feeds two or three valves and it cycles the valves one at a time for a true back and forth wave .

The trick I found was to use small diameter pvc pipe for the tank . I made one ont of 8 inch od pipe and 2 feet tall and it works great on my friends 450 gallon tank.

I only have 20" of headroom above the top of my tank. With the valve and pipe taking up some room, that would leave me with may be 15-18" at best.

Are you going to make up a lsit of parts that you got from McMastercarr ?

I may still play with it.

Joe, I will see you this Sunday.

Thanks,

sanjay.

Ill amke up a parts list for you , You could put the valve sideways to save some space then all you have is a 2 icch 90 elbow off the bottom of the tank .Ill rig one up to a five gallon bucket tonight and see how it does , that should be about the right size .
