I have three unrelated questions regarding a cracked pool filter:
1) Is an epoxy repaired factory refurb as good as a brand new filter? If a filter is new and under warranty and it cracks (not from the reasons listed below) should a new filter be provided or is epoxy repair the norm? If the customer did not realize that the replacement filter was an epoxy repair because the sticker was placed directly over the repair, and only realized years later when the epoxy repair site forms a leak, is it too late to do anything?
2) Can a really dirty filter cause the filter to crack? If, say, the neighbor shoots off about 10 rocket fireworks (illegally) over your yard and all the millions of little cardboard bits land in your pool, along with some big cardboard and plastic chunks and launcher sticks, and they get sucked into your filter and drive the pressure beyond the "time to clean your filter mark," can that cause the filter to crack?
3) In an unrelated incident...if the pool guy accidentally leaves the valve for the side wall suction open on Saturday morning while you are out of town, and on Monday morning when you return you find that 1/3 of the pool water is missing from the pool and the sidewall suction is sucking air into the system (so much so that 4 days later you still hear the gurgling of air bubbles working their way through your solar system pipes on your roof (to the point that the sound keeps you awake at night), could this cause the pool filter to crack? How about the epoxy repaired section of the pool filter? Any other possible damage to the pool system from two days worth of air getting sucked into the system?
Thank you very much for your assistance!
