Hello everyone,

The builder recently installed a Hayward Saltwater Chlorination System (SWG) along with ORP, pH, and temperature probes. These are set up in a bypass circuit (positioned higher than the rest of the system) just before the return collector.

However, when I turn off the pump, the bypass circuit drains by itself, leaving the probes dry. I believe this isn't good for them. I haven't found any leaks and can't figure out why the circuit is draining. Most of the time, it happens instantly, but sometimes it takes a few hours.

Do you think this is a problem? If so, how can I fix it?

I've attached a picture of the current setup for reference.

Thank you!

If the loop is above the water level of the pool when the pump stops the water will drain from the pipe out the return. There is no way to stop that as that is normal flow and equalization.

What model system is it?

What does the Installation Manual say?

Thank you for your reply ajw22.

The flow loop is above water level (let's say pomp at +0.3m above water level and probes +1.5m). The system is Hayward Aquarite HC Low salt with redox and pH probes.

Installation manual does not say nothing regardig the heigh of the system, see attached picture.

I'm not an expert but if you have a piping that comes and goes to the pool it should not be draining by it self, this could happen only in there are leakes?

Other question, I've noticed that the ORP reading change on pump speed/flow. Higher flow-higher orp readings. Is it right? Why should be change?

If you put your finger over a straw in a glass of water you can pull the straw out with the water staying in the straw.

The smallest leak letting air into your pool plumbing is all it takes for the water to equalize and flow out of the pipe. It is great if your pipes are tight and holds pressure. Many pool systems don’t do that and it is difficult to find every leak.

ORP systems do not work well as you are discovering and we do not recommend them.
 
Have learned a lot. Willing to share my lesson and experience.
Hello Cams, good to know that you learned a lot and want to share. I have a lot of problems with my SWG.

New pool with an Hayward HCLS controller for PH and Redox. Here is my issues:
  • The pH readings fluctuate throughout the day from 6.2 to 7.8, while measuring it directly (using two methods: photometer and TFKits) shows a constant reading of 7.4.
  • The ORP readings of the redox probe fluctuate from 620mV to 800mV, even though the free chlorine in the pool remains within the range of 3-4ppm (using two methods: photometer and TFKits). I also noticed that this reading fluctuates a lot with the variation in pump speed (but I think that’s normal).
The problema with this readings are that pH- pump and salt cell clorinator run with no sense. Have you ever had such issues?
