About a month ago I installed a 30 gallon stenner tank with a 50 GPD pump. It has been running perfectly for the past month for approximately 4 to 5 minutes twice a day which is keeping my FC between 7-8 with a cya of 50. It is plumbed into the return line and connected to a kasa smart plug that acts as the timer. I have been very happy with it.
I had some major Wi-Fi problems yesterday that required me to change out one of my Wi-Fi extenders that has the smart plug connected to it. Somehow the settings for the smart plug got messed up and the stenner pump was left running from 4 p.m. to midnight (when I discovered it was still on). During that 8 hour run-time window, the pool pump was only on from 4pm to 6pm. Thankfully the stenner tank was low on chlorine (checked 2 days ago) and my math says approximately 4 - 7 gallons of 10% bleach was pumped into the pool.
The stenner pump pushes approximately 140oz of liquid every 30 minutes. Its safe to say that a minimum of 1 gallon but possibly upwards of 3 gallons of 10% bleach was pumped into the return pipe while the pool pump was off. This would have occurred from 6pm to 8pm and stopped when the bleach level reached the bottom of the strainer in the tank. I discovered the problem around midnight and turned the pool pump on to push whatever bleach was in the pipe/filter/pump through the returns.
I don't know if bleach had backed up and made its way through the filter and possibly into the pump. Other than a super chlorinated pool, is there anything I should be checking or worried about?
I've read the stenner can run dry which it did for easily 4 hours but that's not a problem. I know everyone plumbs their stenner line after the equipment because you don't want high concentrations of bleach running through your pump. Any advice here?
Edit - FC is 32. Pool math says approximately 6 gallons of 10% was added to reach that level. So roughly 4 gallons was added while the pool pump was running and 2 gallons added over the course of 1 hour while the pool pump was off. Leaving about 2 gallons to possibly back up through the equipment and sit for 5 hours.
This is all assuming that the water level in the return pipes and plumbing after the filter stays full when the pump is off. Does it?
