Vacuum Line

Trying to blow out a dedicated vacuum line that's hooked up to a Polaris booster pump.

The booster pump takes in water from the return line and returns it via a line to the side of the pool where I would hook up the vacuum.

I believe they call it pressure side vacuum (?).

I'm using a 3 hp cyclone blower and was able to blow out all my other lines with no problems.

Basically after 4 years of having the pool guys do it I decided to buy the exact blower they use and do it myself with the help of some friends.

I pretty much followed the steps they did in closing the pool.

My question is do I need a air compressor to blow this line because the pool guys did not use a air compressor.

Has anyone used the cyclone blower to blow out the vacuum line?

Any help or suggest greatly appreciated.

Attached are pics of my vacuum set up.

Thank you.

When you blow out the return lines you are also blowing out the booster pump return pipe. Did you see air coming out?

Did you remove all the quick connect fittings at the wall port so that the line is completely open? I believe there is a screen in the wall adapter to filter debris. The cyclone blower creates high volume flow rates of air but at low pressure. So you can’t have any obstruction to the line or else the cyclone will be useless.

After plugging my returns I was left to deal with the booster pump line.

I did not see bubbles coming out of the vacuum return at the side of the pool.

Hindsight might I need to wait longer or my seal was not sufficient.

I guess my question is does the cyclone have enough power/pressure to blow out the line? Have anyone blew out the vacuum line with the cyclone.

You need to detach the booster pump’s 3/4” flex lines at the pipes and blow air directly into the cleaner line pipe that runs from the equipment pad to the pool. You also need to remove any wall return connection valves that the Polaris attaches too. Essentially you need to connect the cyclone directly to the PVC pipe and not use the return line path.

Yes, Thanks. I'm going to try this if the other scenario fails to work.
In a way I wanted to duplicate how my pool guys closed the pool every year. Either they were able to blow it out or they might have closed it with water still in the line.
