Loss of pressure on spa jets

There is one reason why there is a loss of pressure or even suction on a jet fitting. It's that there is something slowing down the natural flow of pressure through the lines. These are the most commonly found things that slow down that flow and how to fix them:

A dirty filter - Clean your filter
A full hair and lint basket in the pump - Empty out the basket
Something is clogging the lines - Call a professional to blow out the lines
The jet eyeball fittings are turned inward - Turn it outwards
The pump is getting old or is not turning as much water - Get a new pump
The venturi portion of the jet is clogged with calcium - Take out fitting and clean it.
The blower is not working - Take it to get repaired
Pump not priming - See "pump not priming" issues
Valves are configured wrong - Speak to your serviceman about correct configuration
