low pressure plumbing parts. outdoor shower?
I've been fooling with rain harvesting the last few years and have a few extra containers. I want to play with an outdoor shower next.
I have the container (55gal plastic drum) finishing up the stand to hold it above the shower and about have the fittings to collect the water, but having some trouble with the outlet for the shower to actually work. everything I find is for a pressurized system and all i'll have is gravity.
I got one of those water controls that uses a pull chain and lets water flow as long as you pull the chain (think back to petticoat junction if you're old enough), but it works with 1/2" pipe. likewise the shower heads I'm find are all indoor pieces, where at best I can take that little control washer (not sure what you call it) out, but it's still about 1/2" piping.
does anyone make lower pressure parts? I've been looking but can't find anything, or don't know where to look or what other name they might go by. I think I could drill out an outdoor sprinkler ring for a shower head (that's going to be my first try at it anyway (and use larger garden hose with it, but the control valve I still don't have an idea for beside the small one I have.
thanks if anyone knows or has any ideas.
