Location of influent port for ORP

[woodsage]

I'm using the Hayward Sense & Dispense and OPR control; the tube for the influent is after the 4 cartridge filter. When I'm testing for chlorine, the difference between the pool water and the test cell is about 4 ppm (pool water higher than test cell, 2.0 vs. 6.0). I've tested for adequate suction from the test cell and it empties a small bucket in no time and there is plenty of water coming from the influent tube.

Would I have more accurate results if I moved the influent port to a location between the pump and filter?

Thanx.

You are fine.

Any reason why there would be a 4 point spread between the pool water and the test cell?

Do you have a UV filter between the water filter and the test cell inlet?

Nope.
