I am doing my sump plumbing and was hoping that someone with a Pentair 40w Smart UV sterilizer could tell me the measurement from the center of the input to the center of the output. I have been searching for days for this measurement and there is nothing online or on their website. My tank just started to cycle and I will be buying it next month and don’t want to wait to do my plumbing. Please help if you can!

It’s amazing the help you can get on R2R. Lol. I have one installed on my tank, and have another sitting in the garage ready for the second tank. So I went out there and took a picture for you. From the center of the input hole to the center of the output hole is 34 1/2 inches. I don’t know whether you want to do what I did, and use flexible silicone hose, but it is very forgiving wherever you place the holes in your stand. Best wishes. (And the mounting brackets from BRS are excellent!)

I thought you might get a laugh at my paper towel test; there is a pump in the bucket of water.
 
Once you know it's not leaking with that bucket setup it's a good time TO (FIRST make sure your pump is submerged with one gallon in the bucket and THEN) ... fill the 5 gal bucket and RUN at desired pump speed and then while running fill the bucket to the top again and get a second bucket marked at 4 gal and time how long it takes to fill then stick hose back in bucket w pump. You can now figure the gph loss from the uv alone to properly set flow.. the other steps are just to make sure the pump doesnt run dry
