Hello, we replaced the board in our salt cell and then several hours later heard a large boom and in the morning saw that our pipes had burst in several places. I would appreciate any help in understanding how this may have happened. Thank you! Pictures below of the damage.
Pipes Exploded. Help!

Salt cell may have exploded by being powered on without water flowing through it. Is the flow sensor functional or is it integrated in the cell?

Hi Everyone This morning I was sitting in my kitchen and I heard a massive bang.. sounded like a bomb or something. I went out and the pvc pipe exploded and water was going everywhere..I turned off the pump obviously. I have a plumber coming out to fix it. But how did this happen. Any...

Explosion near the SWG
We were watching TV and heard a major explosion after exploring in the backyard I went into my pool equipment should and found about a 16 in PVC pipe shredded 8in on one side 8in on the other side of where my SWG Is located. I have no Idea what to think. It appears the SWG somehow was not...

SWG cell explosion
This happened to a friend of mine a couple of days ago, but i'd like to share with you his experience. Notwithstanding I clearly have advised him to switch the SWG machine off while backwashing and rinsing the filter, my friend, not only has forgotten it but he also had the great idea to close...

Exploding pool!!!
Anybody ever see pvc explode like this? Nothing blocked. All pop ups clear. Someone said an air pocket. It appears to have a bit of air bubbles in the sight cover of pump. Air bubbles do come out of some pop ups. Pump was on high speed. 30 psi at filter. It was after salt generator. Salt...

We do not recommend that the flow switch is the primary cutoff for the salt cell. If the switch fails, but still indicates to the system there is flow, when there is no flow, the gas buildup can explode...apparently that is what happened.
You need to install a primary power control that powers off the cell when the pump is off...there are a number of options...
Get a timer and put your pump and cell on the same timer to power down the cell when the pump is off.
Or use a current sensing relay (CSR) to power down the cell when the pump is off.
Or get some automation that will turn the cell off when the pump is off.
You still need the flow sensor, but that should be a secondary cutoff.

Hi! I believe the flow sensor is functional. We just replaced the board and it was working correctly when we checked it after replacing. Perhaps I was looking at the wrong thing? But the light that said “no flow” was turned off, the power light was on, and the generating light was on. When the explosion occurred the pump was not running which typically turns off the whole system.
The flow switch is probably sticking closed intermittently.
What controls the pump and SWG?
We have it on a timer. How would I check the slow switch? I am not sure where to figure that out.
This is the flow switch; it looks pretty old.
Move the selector switch to off and see if the No Flow light comes on.

that means the flow switch has malfunctioned. The SWCG should not be generating when the pump is off.
