Today, (April 10, 2010) I got a reply about this Ebay item..


I apologize for the late response but our home burned down. The unit is designed for shower / tub drains, it is 18" long 1.5" drain in and out and 3/4 lines for inlets and outlets. The units is assembles from copper and is soldered. Unit is sealed in PVC and filled with foam to retain the heat. I have tested the units to 80 psi for city water pressure but not higher, I do believe they would hold 100 psi. The flow rate at 60 psi is 4.5 gpm.
