81 degrees 40% RH and 63 degrees with 75% RH would be the same amount of moisture in the air. By turning on mechanical ventilation, you aren't reducing moisture content in the air. You are just cycling air with a similar moisture quantity at a higher temperature into your basement. The dehumidifier would be the device to use.

Yeah, venting worked a little last summer,
I guess it was only when the basement temperature was equal or warmer than outdoors..

The Santa Fe is pulling out a lot of water down there..
It smelled better, after a 1/2 hour.. My wife noticed it right away.

After it dries up for a few days, the power run-time should cut back..
Maybe the concrete floor is giving up some dampness. Four sumps can't be helping..

Default I kinda expected leakage, but not this bad..

The unit isn't working very well.. The output hose is showing very low output.
Maybe getting a few oz per hour now. I removed the side panel and used the Freon leak detector.
The drain tray and the inside bottom cover all beeped big time.
After blowing it out with clean air, I rechecked and found every thing okay.
30 seconds later, it detected leakage coming down from above,
where the large HX coils are sealed in.. No way I can get to the leak,
without a major disassembly job.

I'm thinking of trying some sealer.. Not sure how to connect the Ebay
sealant canister to the 1/4" SAE fitting. Seems like a 'pierce' connector
like those used on car AC cans, is needed..

Sounds like it's time to make a decision. I have very little confidence in the stop leak product. It may get you through the summer though.

I chopped up a brand new can tapper this year to use with my gauge set. The truck needed a flush and fill after a compressor burnout and the Saturn blew the thermal fuse embedded inside the magnetic clutch. All of the can taps that had flare (acme) fittings on them were car size and wouldn't fit my home size gauge set. So I bought one of these:

I put access valve tubes just like the one in your unit on the ends of the hoses.

Now both halves connect right up to my gauge set.

Put in some UV dye and actually find the exact spot of the leak. Most likely it would be at a brazed joint somewhere.

Mike, I know where the leak is located and could not get to the exact spot, without ripping the HX section apart.. Not something I want to do..

Jeff, I have a brand new can tapper too.. (and a bag of access valve tubes).
Is the car type can tapper really going to work with the R410a leak sealer?

I might need some small clamps for the access valve tubes..

Thanks,
Rich

I can't tell from here, but most of the small "spray paint" cans have the same tops on them. I believe they are 5/16 fittings. 99.9% of the stuff they sell at the HVAC store (Johnstone, United, etc.) has 1/4 inch flare aka acme or the same thing as nitrogen cylinders. The old R12 and R22 "spray" cans had 1/4 inch fittings on them, and when the industry mothballed CFC refrigerants, that's when all of the standards changed. Now you never know what type of fitting is going to be needed until you see it. Even the old fridgie techs carry a universal "fits all" adapter set in their bag. Cuz it sucks when the specs lie.

Added some R410a to the Santa Fe and it's working great.
The low side pressure came up from 40-50 PSI to about 90 PSI.
Couldn't get it over 100 PSI, so I stopped trying and turned off the flow.


I'm buying some of this sealer..

"Product Description

Pro Seal - Up to 4 lb System - AC Stop Leak - Sealant formula developed by NASA for critical systems such as space flights, submarines, ect.
Sealant Can - Compatible will all oils (Mineral, POE, Pag, ect.) and all refrigerants including 410A. Will seal most small leaks in Air conditioning systems. "

I wonder if this stuff will work on a leaky BMW?
