How To Blow Out Main Drain Inground Pool? (Important Facts)

Once your main drain cover is off, place a pool plunger over the drain. If you repeat this motion several times, the clog will be forced up and out of the way. If you don’t have a pump, you can also use a garden hose.

If you’re using a hose, make sure the hose is long enough to reach the bottom of your drain, but not so long that it’s blocking the flow of water. You may need to adjust the length of hose depending on how much water you have in your home.

There’s even a video explaining it all!

This is a good sign that you’re doing the right thing. Once you’ve done all of this, you should be able to see that the water level in the tank has dropped significantly. If it hasn’t, it’s probably because you didn’t blow enough air into the system.

Put the shop vac on exhaust and place the hose on the valve and blow out the line until only air is blowing out at the skimmer. The power should be turned on and off a few times to make sure the water is out.

The extension acts as a plug and will prevent the skimmer from sucking water out of the system. If you don’t have a vacuum pump, you can use a hose clamp to hold the vacuum hose in place. You can also use an air compressor to blow air into the tank.

This will allow the water to drain through the hole and out the other side. You can also use a hole saw to cut a 2-ft. diameter hole, but this is more labor-intensive and may not be as effective.

What PSI Do I need to blow out pool lines?

When blowing out return lines this is a pretty low threshold, however when purging water from the main drain line a minimum of 4 psi of pressure must be achieved to push against the 8 feet of PVC pipe.
