Well, I plugged the sieve today. I used the pvc cement all over the connections and it seemed to work. Started raining befor I finished so I will have to double check it again tomorrow befor draining it and hauling it all back into the house. (tank is set up on the back porch for the leak test). The overflow, drains, and spraybar work flawlessly, IMO,

now that the leaks are fixed. It is quiet, too, even though I have not replaced the cap on the standpipe yet. The cls does make a gurgling sound when it switches back and forth, but otherwise seems good.
I'm afraid this is as far as I will likely get on this thread. For anyone who has not seen my other posts, I will be going offline for several months starting tomorrow...er today...or whenever AOL cuts me off!

When I get back online I'll post pics to show the tank up and running.
Thankyou all for the great advice, tips, shared knowledge and especially for making this such a friendly and enjoyable place.

Peace.
