Blowing Out Water Lines

Our winters are generally mild here in the Pacific Northwest so we camp throughout the year and I don't do a full winterization of our rig. I drain the water heater, empty and remove the water filter, open all taps and pour RV antifreeze into each sink, the shower and my tanks after every trip. This year I'd like to take it a step further and blow my lines out but I want to be careful and not use too much air pressure. For those of you that use air to clear your lines what PSI do you set your air compressor to?

Thanks in advance for your help.

I set my compressor at 40 PSI. I really wouldn't go much higher then that.

25 psi is what's recommended.

Pumps run between 40-45 psi and regulators are around 50-60psi, PEX is rated around 100psi.

40psi should be adequate pressure for doing this job for any trailer.

I do about 45-50psi as my system should handle that. If it fails there, it will when you least expect it!

Edit: I also carry a PEX crimper, pipe and fittings just in case!

40 psi at a wholesale water meter...................so 40-45 is perfect.....thats what I have done mine at for 25 years of R.Ving, and have never had a problem yet.

Do you also use RV anti freeze in the water lines?

No, The only anti freeze I use, is a cup of anti freeze down all drain traps. I also remove the H/W tank plug for the winter. The last thing I do is make sure that the holding tanks are empty from the drain traps old water.

I run my regulator down to about 30-35 psi. Keeps thge faucets from "spitting" too much. Higher air pressure,and you can damage lines (especially when you start exceeding 50 psi), plus it makes a splatter mess.

I hang a hand towel over my faucets to keep that in check.

I'm not saying 40 psi is right or wrong just stating what's in my manual.
Do as you please.

If you have your faucets open, and your bottom drains it won't matter how much air pressure you use. You'll never be able to put enough air into the lines to build up any type of pressure to blow a line apart, unless you're using a commercial air compressor, and then you would have to have special fittings to accept the cfm it would take to bust a line. I have compressors from 40hp to battery operated, and I run 90-120psi from the compressor into the water line, and the back pressure guage barely moves.

If you have a Flagstaff you need to use no more then 25 PSI, all others can use 40-45 Just picking at you Turbo. I was going to assign you an acronym by using your new "Free Advice Giver" name, but once I shortened just using the first letters it just wasn't right

Seriously to the OP, it's perfectly safe to 40PSI. Here are some links if you don't believe us:
