Hooked up my washer in new home and connected hose to the drain which is at the bottom of the wall and from that up runs a 2 pvc pipe. Everything looked good and was until it went to drain and water shot out the pipe. Is it clogged or is there a valve that hasnt been opened?
Ok my best guess is that is a solar powered smoke detector, and that the batterie(s) are going bad.
Check your closets and look for a control panel. They might be hooked up to some kind of receiver or nothing at all. If you find nothing then just ask the builder
P.S. I don't think it's advised to use less hardener than half and half for good results (in fact, *exact* measuring is usually urged epoxy resins are different from polyester resins in that way.) HTH, Diane B.
