A little late replying, but yes, I still do use the Intex plungers. Incase I didnt' say it, I also use the "big" Intex inlet and outlet, plungers that came with the big pump and the 1 1/2 inch hoses. I may also work on hard plumbing a bit more next year. Found 1 1/2 inch pool/spa cream colored tubing at Lowes to try out. Looks heavy duty enough, but problem is connecting it to our unique Intex stuff. More experimentation needed.

Glad everything is working better.
