DIY 12V shower
During our last extended power outage (8 days, February ice storm), we used a little Zodi camp shower that uses four D-Cell batteries. It put out a pathetic little dribble of water. We later got the bright idea to build a better shower.
This unit consists of a 1gpm RV demand water pump, an RV handheld shower head with on-off button (the RV pump turns off when the button on the shower head is pushed off (there is an extension hose attached), a 3/8″ uptake hose with filter, an on/off switch and a plug that fits a corresponding socket on the battery. We have a big deep cycle battery that we got to maintain tropical fish life support (no longer have the fish). The little filter on the uptake hose was pilfered from a small drip irrigation filter, the open end was sealed with a little plastic wrap and an o-ring. The uptake hose is dropped in a bucket of warm water and clipped onto the side of the bucket so it won’t fall out. All contained in an old tackle box.
The pump delivers a very refreshing shower, of just the right pressure!
