pressure problems with new de filter

[Poconos]

Just a comment on the pipe diameter pic. The 90 on the left looks like a drain/waste 90 deg. These are not designed for pressure. Sched-40 pressure fittings look like the 90 on the right. The PVC is thicker and the bonding length, how far the pipe goes in when assembling, is about 1.25" I believe.
