Hey all,

Attempting to close this myself after my first year of pool ownership.
The returns have been blown with a compressor and I hear a small gargle after shutting the pressure off. This tells me that there may be a little left.
Should I just pour RV antifreeze down the two returns?
I have made pipes with 90 degree elbows that are screwed into the returns then capped. This means I can leave the water a little higher as I have an auto cover...

Any suggestions on that last bit left in the pipe?

thanks

It's probably fine as it is You might want to take one more stab at blowing the water out - when you blow out lines, the water clings to the sides of the pipe, you need to periodically stop the air flow so that the water can puddle - the next blast of air will remove most of the puddle, repeat the blow/ stop/ blow until only a very fine mist comes out. On the other hand, say you've still got ~ 1/2 cup of water in the line, 1/2 gal antifreeze will be more than enough to mix with the water and protect the line. (if you need info on a couple different ways to make the water puddle, I'll happily provide them for you )

One other consideration in this is how deep the pipes are run in the ground - if they're below the frost level, that's a big plus - but I'd still try to get all the water out and use some antifreeze!

Thanks for the response Waste.
The trouble is I have to blow the pipes and cannot see the pool from where I'm doing it.
Will have the missus to confirm and will purchase a little RV AF...

Cheers

Dannyboy, this is usually a 2 person operation
