How to bleed air out of pump, filter and system?

If your spa or hot tub has been working fine, you just drained and refilled it only to find out that the jets or heater won't work, or you're getting some strange reading on your display, this is where you call 'home'.

How to bleed air out of pump, filter and system?

We have a Coast Spa that only has one pump. What is the optimum way of bleeding air out of your spa? (Filter and Pump).

Thanks so much.

Bleeding the air out of a pump to prime it is either very easy or very difficult depending on how the spa manufacturer installed the pump.
What is happening is that there is an airlock in the plumbing. Sort of like an empty glass inverted in a tub of water. How do you get the air out?

If the pump is installed with the pump discharge oriented vertically, this should be easy to do. The worst case is with a side discharge pump rotated to the bottom. On many pumps, there is a small drain plug that you can unscrew PART WAY to allow the air to bleed out. Open this until water starts flowing out. (Do this with the PUMP OFF).

Another way is to loosen the pump union (nut) on the pump discharge until the air is out and water comes out. Then retighten and start the pump.

A picture of your pump plumbing would be nice too.
Good luck!
