Re: AIR SUPPLY PLUMBING
I use a Thomas diaphragm pump, and have been for 30
years. they lst about 12 -15 years and cost about 150 dollars. I pipe the
fish room with 3/4 and 1/2 inch PVC. My 3/4 inch pipe is 30 years old and
is schedule 80 which was the first pipe available. I have screw type brass
valves in this pipe because they thread through the thick pipe. Also
because that was all that was available. For the past 15 years I have use
plastic valves that are available everywhere at about 20 cents each. I
drill a hold in the PVC and insert the valve. the valves come apart ..so
if they ever need replacement because they are not holding the pressure, I
pull them off and replace them.
Must say I have not replaced a plastic valve in 10
years. The pump has a stand 1/4" output, I immediately climb to 1 inch
flexible clear pipe for 3 feet to reduce vibrations; then I go to hard PVC.
The Thomas pump is listed in Granger Catalogs and has
worked well. I am leaning toward a new linear pump when my newest pump
(9years old) wears out.
I will make a photo available to the list if anyone is
