Jet Drive Water Pressure Relief Kit
The kit from Pack-A-Jet will come with a brass pressure relief valve with 1/2" npt bypass outlet and a stainless steel extension tube for easy installation. Direct fit to the Berkeley models 12JC and 12JG with 3/8" NPT water inlet, but can be used on other models as well as long as they have a 3/8"NPT water inlet on the inside of the boat. Will NOT work on 12JE model or similar pumps where the water inlet is on the outside of the boat. In that case you'll want to buy a pressure relief valve only and a simple T fitting to adapt to the existing inlet tube.

The pressure relief valve opens at app. 12 to 15 psi to move excess water overboard.
