I tried to find it by going under my house, and all I found was a grey rat snake about 1.5 ft long (which is fine...he can dine on mice all he wants). The underside of my house sucks...the ac unit is all under there...so making it from one side of the house to the other is a huge pain in the ass. I wasn't even able to make it over to where the dang line enters the crawl space.
The main problem is, I know where the old pool used to be, but couldn't find where the dang spa used to be! I looked all over for the line, figuring it'd be near the pool, and nada.
