I had several leaks in between my pump and filter so I replaced all of the plumping. I noticed the threaded inlet (where the plumbing enters the sand filter) is slightly cracked. I made it worse when tightening the new pvc connector. Though there are no more leaks in the new plumbing, there is now a steady leak at the inlet. Any ideas on how I can seal this? Need to get this stopped asap. Thanks,
