Bit of back story... living in an older rv... stationary... I am presently not using the water system in the rv... and have been using a bucket shower I made.. works ok but kinda low pressure, and heating the water takes awhile.... I purchased an Eco temp L5 from amazon.. be here in about a week... I tried using a 1/6 hp utility submersible pump , with a garden hose and a nozzle that could be easily left on( not a squeeze grip.. )it worked well, but went through a bit of water, and it took 6 or 8 gallons to get about a four and a half minute shower.. I know.. take a navy shower haha... the problem was heating that much water used a lot of propane and time... like over half an hour with my BBQ side burner.... I was thinking the pump would work well for the Eco temp, but I'm not sure if it is at least 20 psi... seems about as strong a flow as a garden hose.. but maybe not.. for now, having ample shore power, I thought it would be easier than going the 12v route, although when I get set up to go mobile, that will be my choice. Anyone have any input? Thanks.
