Greetings,
DIY plumber here. I hooked up a passive thermosiphoning system yesterday. Almost works, now I have instant "warm" water, then cool, then finally hot. Close but no cigar.
Any suggestions for tweaking greatly appreciated.
Details...about 50' run to most distant fixture. Supply is 3/4 main with 1/2 to fixtures. Return loop is 1/2. Tied into bottom of electric water heater located in basement.
Per something I read, I tipped the swing check valve into a slightly open position when installing. Is that the problem? In researching the project, another "authority" suggested drilling an 1/8 hole in the valve flap with no mention of tilting the valve open. Other sources don't mention any special treatment of the scv.
Have most of the supply and return insulated but not all. Can't believe that's the problem. Plan in leaving the last 15 feet or so of the return uninsulated.
TIA for any thoughts,
Todd
