I'm a brand-new pool owner. I've been spending the past few weeks educating myself, in no small part by reading owner's manuals. I have a ~12,000-gallon pool with a Hayward S244S sand filter and a 2-HP Hayward Super Pump.
Today, my wife thought it would be a great idea to mess with the plumbing without having a clue how anything worked. I was absent at the time. She was trying to block off our automatic cleaner, but ended up adjusting a valve so that it blocked ALL flow from the sand filter. After hearing "noises", she came and got me.
I immediately opened the valve, of course. I did not take the time to note the pressure reading on the filter, and I'm not sure I even want to know what it was. The valve was closed for about 5 minutes, I'm guessing.
Nothing is obviously amiss... But I'm the neurotic type, and I'm still in the "Wow, this cost a fortune!" phase. What are the chances that my plumbing and/or equipment suffered damage as a result of this?
