Blowing out lines - Air Compressor

[ChuckD]

True enough. And if I'd typed out my complete thought (what, you can't read my mind?) I'd have added that I'd then slap the rubber plug and Tape of Duct on the pump end. The poly would really just buy me some time to get the vac off and plug in place before too much water re-entered the drain. Kind of a cheapo one-way valve, albeit a leaky one.

Needed would be a ring-type affair to fix to the end of the telescoping pole larger than the drain, bent at an angle to press the poly onto the drain as the vac was turned off (and a wife with a good sense of humor, which I have). Got an old skimming net that I'll sacrifice.

My returns are roughly 14" below the water.
My main drain is 8 feet.

The guys that blew it out last year brought out one of these...http://www.poolcenter.com/winter_sup...mighty_vac.htm ....
Had the main drain blown out in a few seconds and threw the valve at the pump. so the drain line was air locked.

I believe my gas blower has less MPH than my neighbors electric one....but anyway.

I have a nice 25 gallon - twin cylinder 220 volt compressor. I will buy one of the above blowers if necessary. But I dont really want to spend that kind of money if I dont need to....
Surely someone has used both and can let me know what is best or what works.
I plan to try the compressor soon. I will hook up a regulator to the line and put a quick connect on a plug in my stand tube in the skimmer.

thoughts?

We always use an air compressor. Ours is 5hp and 20 gallons. Gets the job done nicely.

You'll be OK using yours.

I puchased the Mighty vac http://www.poolcenter.com/winter_sup...mighty_vac.htm and used it now for two years.

thanks doggie.
What was the pressure set to?

thanks Kevin

We go 20 to 25 psi. Good luck

I've always used my shop vac (5hp Craftsman) to suck out the return lines, skimmer, pump basket reservoir, and chlorinator before the SWG. Has worked just fine for my 10 years of IG pool ownership. The only drawback is you have to empty the container, obviously. Just wanted to throw in another option for those that don't wish to buy an expensive air compressor or blower.

Hope this helps, Tony

Mine was set to about 50 while ago in my test.
It appeared to be fine.
Maybe I should back it off.
Tomorrow I plan to close the pool - after I get a few more supplies later today.

Anyone else have an opinion on the best pressure, but not too high?

thanks Kevin
