Where did you got you valves and piping thinking of doing some DIY
Did had a dream that my tee off to the skimmer came lose and flooded my living room. What happen after the dream was the return hose through the chiller came lose and mess up the floor. Luckily my mother in law was at home and so she get my kids to alert my neighbour who in came and turn off all the equipment. The Swing Check Valve manage to stop blackflow from the main tank. Only the water in the sump return compartment was emptied.
I was worried that this going to going to happen as I remove all the clamps on the hose to facilitate me to do some DIY piping(took me a few days becasue no time to finish it one shot). Now all clamped up. No more trying my luck!
