This morning at 11:30 AM, the Sanyo air pressure reading was 340 PSI (after sitting for 93 hours).
Low Temperature last night was 40.3°F, so a 10 PSI drop was not unexpected.
I'm going to declare 'Leak Repaired'!!
And head on over to HD and get some copper to build a lineset test rig.
14:00 Back from HD. Got 10 feet of good 1/4" copper. But the big stuff I wanted,
1/2 in. x 10 ft. Soft Copper Type L Coiled Pipe-LSC3010PS at The Home Depot
Actual inside diameter (in.) : 0.545
Actual outside diameter (in.) : 0.62
Assembled Depth (in.) : 120 in
Assembled Height (in.) : .625 in
Assembled Width (in.) : .625 in
Only turned out to have a 0.5" OD... So, that's $19.11 that I'm going to save.
The solution to this problem is to make my test loop out of 10'x 1/4" line.
I'll make an adapter using some regular old 1/2" (0.625 OD) Type 'L' copper pipe.
I'll braze a cap on it (cap will have a 1/4" hole) and flare the other end..
