Skimmer thread size

[Esiebert7625]

Hello there,

I’m trying to connect a male threaded pvc fitting into the skimmer bottom hole to blow it out and it seems that a 1.5” mpt is slightly too small and won’t thread and a 2” mpt is too big. Is there a chance this is an off size or are all fittings usually 1.5”? Don’t know much about the skimmer but the pool was built in the 1960’s.

Thanks!

If you are trying to remove some debris in the skimmer line, I put the pump on high, place a tennis ball in the skimmer hole which causes the suction to really increase. I pull and place the ball several times over the hole to create a plunging action. This normally clears out the debris and then I clean my pump skimmer basket. Hope this helps.
