As a returning member to the CDC team, I designed and fabricated a new CHT that is grooved and quick to assemble using copious amounts of PVC glue. The float valves are modifed such that they can remain submerged under the water level in order to prevent calcium buildup. Also, overflow weirs and a clear lid are incorporated.
I fabricated a modular and chlorine resistant constant head tank. The new CHT utilizes non modified float valves and has some flexibility with adjustable head.
