Waterway Clear Water II pressure gauge assembly is easy to change. Remove the filter lid from the tank base, and then remove the "tie nut" from the inside of lid (counter clockwise). After tie nut is unthreaded, push the threaded shaft up through the lid. If it is stuck, you may need to tap it up with a rubber mallet.

Two Waterway Plastics sand filter draincaps that almost look identical, but the current model 602-5321 has a much more rounded thread. The "older" style cap has an angled thread. If you have lost the drain cap just take a look at the threads on the ni**le on the tank. Both caps require oring 805-0224. Both caps have the number 602-5320 embossed on them, but the internal threading is much different and they are not interchangeable.

Angled thread is 602-5301

Does your Waterway multi port valve leak? Water leaking out of the backwash port? Instead of replacing the entire valve, which means disconnecting all of the hoses, you may be able to just replace the "key cover". This assembly is the complete internals of the valve.

Does your Waterway Hi Flo II pump leak? Instead of replacing the pump shaft seal you can try replacing the entire "wet end". If your motor is in good operating condition this might be the best option.
The Hi Flo II pump housings are the same for all horsepowers, only the impellers change. The rear part of the wet end has these numbers on it 315-2510 and 315-2520.

Some Waterway "wet ends" have faceplates with several plugs threaded into the pump face.
Not all of these plugs are plugging. Generally only one of the plugs is drilled through the faceplate. If you are modifying the faceplate with barbed inserts, you will need to drill the faceplate.
