My spherical Jacuzzi TM31 sand filter srpung a leak and I need to replace it. Right now, Plast-Aid is holding the leak down but that won't last long. Is there any good reason to replace the TM31 with another sphere? That model is discontinued and the other spheres I have seen advertised are over $1000. I have 2" plumbing except for the 150' round trip of 1.5" pipe to the roof solar panels.
I am looking at this model as a replacement:
