Not much compared to most of the exceptional carpentry and plumbing in this section, but usefull .

I used to have a UVS on each tank, but since I don't ever run them unless there is a problem (and there hasn't been one for over a year), I decided to sell off my "extra" - it's on the way, Mike - and keep just one.

So, I had to make it easily portable; to spot treat a tank if it needed it.

I accidently put the ball valve on the output instead of the input, but I don't think the added pressure (in the event that I slow down the current) will be a problem. The UVS used to be inline, and I'm sure it was under pressure in that series......nevertheless, a goof. The UVS is rate for 100-200 gph, and the pump is rated at 160gph, so there is a good chance I never even have to slow the current anyway.

The 90 deg elbow on the output is not cemented, so that I can direct the current.

I would have prefered to screw PVC fittings directly on the input/output of the UVS, but the thread are not a standard size. They are likely metric - larger than 5/8", but smaller than 3/4".

Oh man. I just saw Diablocanine's thread. His is much better . Now then, will anal retention force me to do it over.....YES hahaha.

Much better design this time (inspired by diablocanine).

The ballvalve allows the current to be slowed through the UVS, without creating any backpressure on the pump or the sterilizer. It also adds a TON of structural support. This thing is bombproof.
