I was reading at Spa Babes web site that if you have a jet that is cloged that it will cause The air valve to leak. Im new to spas and this forum site also. I have good flow from my jets with the exception of one jet off of each pump. I have just gotten a Blue Ridge 6 person spa (used) model 45 I think. If these jets being clogged could cause air to leak out of the air valve and run down the air lines. (I noticed it only does it when the air is turned off. It runs down the lines) How could I unclogg these jets or do I have another problem?

Hi Roy,
All spa jets incorporate a "venturi" within the jet body. This is a cone shaped devise that increases pressure, and creates a vacume effect. The vacume effect draws air from the air control valve. The jet body seperates the high pressure of the pump from the vacume created by the venturi with a seal.
When this seal wears out, it allows the pressure from the pump to "contaminate" the air control circuit, and force water out of the air control valves.
Yes if the jet is clogged, it will leak from the valve, but a reduced flow will be noticed.
If the seals are worn, ...OR if the jet internal is loose, you will have the same result.
