My spa is raised about 40" above the pool. Prior to remodeling my air intake was just beyond the pool deck raised about 8" above ground level with a one-way valve built in. inlet was pointing toward the ground. Not a lot of bubbles so thought to use a 1.5hp Silencer blower. For asthetics I moved the air line about 40' to the equipment area. Removed the one-way valve and attached a 2" pipe to the equipment area ending about 10" above the water line. Attached a 1/4 lb one way valve. Water level was lowered enough to drain the air inlet pipe (used compressed air to clear) as it was filled with water. NO air at jets at all. Added the blower directly to the valve got some air from only one of the 4 jets then the motor overheated. I'm pretty sure the hartford loop would help but thought it should work as describe alibi inefficiently.
Wit a one way valve above the water line how the the hartford loop help? The pump is a pentair intelliflo VS set at 3200 rpm when in spa mode. 100 CuFt DE filter pressure go from 10lbs (2300 rpm pool mode) to about 25 lbs. Seems like a lot
If I need the loop. from 1' above water level (one-way valve included), once it turns down - do I need to go all the way to the ground before returning vertical? if not then how far from the top of the loop do I need to go (toward the ground) so as to make the hartford valve most efficient? Then back up to some point to attach the blower. Is the standard 1' enough
Thanks for listening.
