Pool pump not holding pressure

[PoolDoc]

The most common cause of a pump losing prime is a suction leak, allowing air to enter the piping. Places to check:

1. Thread entering pump.
2. Valves between pump and skimmer/drain
3. Unions between pump and skimmer/drain
4. Any fittings for a feeder or other device connected between pump and skimmer/drain
5. Pump winterizing plug loose.

I am having a similar issue w. a Krystal Klear Intex Sand pump. I am going to check the threads and valves
you mentioned. Not a lot of air bubbles visible, but just not pumping like it did last year. Pump is now a year old.
Thanks for any additional suggestions.
