Sometimes my Hobie tank just won't prime, don't know why. Even filling it with water doesn't necessarily make it work. The following method always works.
1st you need:
PVC hose bib to 1/2" fitting, 1/2" coupler and 1/2" flexible irrigation hose:
Attaches to the pump this way:
I have a plastic snap clip in the back of the tank to keep the hose in place and keep the water flowing around the tank:
Its real easy to pop the hose up out of the tank:
Two modes here. If the tank won't prime, then a little suction on the tube to draw salt water into the pump works every time. When the water starts flowing, I put the hose back under the clip.
The other mode is if junk gets caught in the pump intake and stops the water flow. If you blow into the hose, it will clear the pump intake and you're good to go.
