Spa plumbing air line

[damb]

I'm just about to finish up the plumbing for my spa and I would to see if anybody know if the air lines should be looped. I can't seam to get to a few area so I was just going to tee off another jet and cap the one end.

No need to loop an air line around the spa. They have very little loss if large. Just keep the pipe large (2.5") close to the venturi tees.

Are you planning to put in a Hartford loop?

Thanks
Yes Hartford loop, 2.5" supply lines down to 2" at jets and the air line is 1.5". The equipment is about 3'-4' away.

Air line is 1.5"? That is really small even for 3'-4' run. I would use minimum 2".

That's what the jets have. Should I up size at the Hartford loop?

 

[mas985]

I would keep the air line the same size all the way back to the pad. Smaller air lines will create more noise not to mention less bubbles.

I understand what you're saying, but the waterways jet bodies have 1.5" air lines and the Hartford loop is already buried in concrete so the only option is to up size at the loop to the pad. Do you think this will help?

It couldn't hurt. At least the noise won't be as bad.
