MJ1200 losing gph?

[AdamNC]

Do these pumps lose their gph over time? I've cleaned the pump and cleaned the internal intake tube on my AquaC skimmer with a wire brush but I seem to have lost skimmate at the normal cup level. So clean pump, clean cup neck and no clogged intake tube. It also sounds quieter. The skimmer and pump are a little over 3 years old.

Get yourself a new propeller. old one wears down on the shaft and bores out the hole through it. normal wear. cheep fix.

no clogged intake tube.

You're talking about the injector, right?

As long as the injector is clear, then I'd have to suspect the impeller as mentioned above.

However I always tell folks to go back and break down the whole pump and skimmer one more time. Soak in vinegar if you didn't. Scrub with a brush if you didn't. You get the idea.

If you let the pump completely air-dry, calcium deposits are 100% easier to see. They're transparent when wet if they are thin enough....but they can still cause problems if they are in the wrong places.

Yup.

And yes. Everything wears out.

I figured as much but rather go through all the work first, thought I'd ask.
