This is what I did today. There was a crack line in my Hayward pump housing. Epoxies and other bonding
products won't work with this type of plastic and in this high pressure environment. I was not feeling like
spending $180 to replace the housing so using plastic molding technique with a soldering iron I took care
of the problem. " This tool needs to be 60 watts minimum because you will be working on hard plastic". You need to take
out the motor because the crack need to be fix on both sides. Look at the photos. Wear a mask, dangerous fumes.
