Antifreeze in skimmer lines - and compressor choice

[Poconos]

That compressor would be fine if you want to plug the lines and pressure test them but for blowing them dry you want something like a shop-vac that supplies a high volume at low pressure. Even better would be a leaf blower. Most shop vacs are designed to suck, not blow and may have to be modified a little to get sufficient pressure. What they do is on the pressure side of the fan they vent a significant amount of air away from the blowing port to always keep enough air flowing to cool the motor even when the outlet port is blocked. If you're handy and don't mind voiding any warranty you can figure how to get around this. Every manufacturer is a little different.

Hi Tomcat.

I would certainly listen to Al's advice!

I think a shop vac would allow you to vacate most of the water from the skimmers - especially if you'd used the pump to suck as much of the water out of the line before blowing them.

Whatever you use to blow them, apply air for ~ 5 seconds till the gush of water out of them becomes spray, and then wait ~ 10 seconds (so the water clinging to the pipes can puddle) before reapplying the air. If you do this a few times, you'll get the majority of the water out of the line. At that point, add a gallon or so of propylene glycol, to mix with any water left in the line, seal the port and protect the skimmer body from ice expansion.

The MD is a different story - if you'd like some advice on protecting it, simply ask and we'll proffer our advice.

Have a great winter! Ans I hope to see you here, if not over the winter, at least come next spring
