We have a Paramount pcc2000 system with several cleaning jets. Assuming you have checked the system's operation and are sure the jets are bad, then the low buck alternative for cleaning the pool would be to get a suction side cleaner. IF your skimmer flows to the filter, then an adapter can be fitted into the skimmer and a hose with either an automatic or a manual (vacuum head on a wand) cleaner can be used. If your system has only 2 pop ups, I figure they are about 75-100 bucks each. (thats what they run for our pcc2000) If you do not have hose, adapter, wand/pole, and manual vac head, figure about that same 75-100 bucks for a new setup. Probably less if you are a frugal shopper.
If you are searching for help locating a source for used or reconditioned pop ups, then the usual ebay and craig's list might be helpful. I have never found used or reconditioned pop ups for the pcc2000. Just reconditioned control valve assys.
I have not found a "generic" pop up that will replace name brands.
Our pool can't support any skimmer attached cleaner, due to the plumbing setup.
If this isn't the correct info you need, give us some specifics on what alternatives you are looking for.
