Master Spas uses Balboa control systems and Waterways pumps which are the best OEM components available and, until two years ago, used Waterways jets as well.
However, at that time, they moved to the newer CMP jets.
This is an illustration of how these people let the engineers decide what’s best and keep the marketing folks away from the drawing table.
CMP jets are next generation and are compression fitted to the shell without the use of silicone.
This technology virtually eliminates the possibility of jets leaking in the future.
Master is the first manufacturer to move to this new tech but we think other high-end brands will follow suit.
The SQR came out about 7 years ago, but not sure when Master Spas switched to the SQR design.Apparently two years ago they changed over from Waterway to a new type compression fitting that doesn't use silicone sealant.
Noooo!!!Maybe I should disassemble all of them and apply some kind of silicone grease to keep them from seizing?
Remove them, yes. Once a year at least.
Clean them too, and maybe soak in vinegar or 10% muriatic if they have scale or the rotating parts are sticking.
But do not, I repeat; DO NOT put any type of lube on them. Not even spray silicone. It becomes a debris trap that will ruin your jets.
If they are siezing from grit behind the jet, get a pair of cheap panty hose (old school) or
