drian plugs keep cracking

[zwluxx]

Hi,

Recently, I have cleaned my filters on a Sta-Rite systems3 filter system. I changed the O-Ring on the bottom plug. I could not find any o-ring for the side plug o-ring in the Leslie pool store. However, they have a replacement plug with O-ring, so I bought it ( A Leslie version of Hayward SP1022C) and replaced it, which seems to fit my systems3 filtering system.

Two days later, the new plug cracked, I thought that it was the problem of the product, so I used the new O-Ring on my old plug and put it back into operation. A week later, my old plug cracked as well.

I do noticed that the Leslie O-ring seems to be a bit thinner than the original. In the mean time, I also ordered a Hayward SP1022C on Amazon, the O-ring seems to be slightly thick than the Leslie version as well.

My question is, was the slightly thinner O-Ring from Leslie part cause all my headache? Thank you very much for your help.

Maybe, I tightened the plug too much? Shall I just tighten it with my hand, no screw driver (I need used screw drive to loosen it)?

Are you talking about the "O" ring or plug cracking
If it's the plug it would have to be tightened so that it don't vibrate loose
You may have overtightened it but I wouldn't have thought that a screwdriver would over tighten
