UV Plumbing Advice

[Brandon Rush]

Looking for advice on plumbing my UV in line horizontally or putting the output to the sump. If I plumb it inline I'd use a Neptune Flow sensor. Any advice/recommendations/pictures?

Can you post a picture of where you would like to place it?

Pictures always help. Key points I’ve learned on plumbing UV is make sure to plumb it so when the pump turns off it stays full of water and plumb it it pump into your tank not back into your sump.

That's basically the way I had to plumb mine. I would suggest a ball valve before the UV to control it flow as you have shown.

Can your UV sterilizer be too big?

Ya, I took the screen shot before placing my order. I just hope it's not missing pieces/ has damaged pieces, the description was "box damaged" I figure if I end up needing to buy a quartz tube, bulb, or a couple gaskets it was still a good deal... I figure worst case if its beyond repair, or...

This is a awesome way to plumb it

Is #1 line returning to tank?
Is the a pump feeding #2 going through the UV? I assume so.
Any reason why you have merged 2 return pumps in to 1 line in #3?
#4 is return line to DT, I assume.

Essentially, you have 3 return pumps.
If I were you, if your return pumps can enough flow, I would run then independently and not merge the lines in #3. If you merge them be sure that you have check valves before the merger on the lines. One return line would go direct to tank. Other return line would be plumbed through the UV to the return. The 3rd return pump in #2 wouldn't be needed.

Would there be a disadvantage to plumb it inline? rather than return it to the sump?

Thanks for the input. #1 is the 2 returns going to the tank. I have no choice but to combine the 2 pumps due to my sump design and layout. #4 is an input line from a mixing station. The UV will be fed by the combined return pumps and controlled by the ball valve. #2 is an output line and not an input line.

Recirculating back through the sump isn't the most effective, but the drains from the DT will mix with the sump and over time it will treat all the water volume in the system.

My basement sump forces me to recirculate back into the sump. Still works:

So from the way things are sounding a closed loop system is superior?

Yes, closed loop is always superior for effectiveness and efficiency.

If you can return the exit from the UV back to the DT, that's the most effective. But recirculation in the sump works, just slower.
