my tubes are double wall.. holding up great so far.
Pipes to and from collector are all 3/4 copper.

When water is returning to my small drainback tank in the basement you can hear the purculation occuring like a coffee pot during summer but no damage to anything yet. Systems been terrific.

Purchased my evacuated tubes thru www.houseneeds.com
Went to their website the other day and noticed they don't sell evac tubes anymore from what I can tell. I wrote to them cuz wanted to buy a couple more but so far no one has gotten back to me.

Thanks for your response.
Have a Happy New Year
