My '72 Safari has a Thetford "Aqua Magic". The hand sprayer with the toilet was cracked and leaked so I disconnected the head and just stuck the hose end in the toilet. Of course there are the inevitable hassles when it slips out and you don't notice and flush and water squirts out.... I got a kitchen sink sprayer to replace the end, but the fittings are different. Next I got the whole sprayer assembly (hose and sprayer) from Home Depot, thinking I'd just replace the whole thing.
Well that's a nearly impossible task. I took the 12 --count 'em--12 screws out of the back of the toilet thinking I could access the sprayer fitting there, but noooooo
Next I got a mirror and flashlight and looked up the back of the toilet to confirm my suspicions that the hose for the sprayer is attached up in there permanently--it looks like. Next, I took the sprayer/hose kit I got at HD apart and compared the fittings. The ones on Thetford are smaller than the ones on the HD sprayer. So, is it possible to replace the sprayer or are we stuck just sticking it in the toilet forever? I even wondered about cutting the hose, trying to find some sort of plastic tubing that would fit inside both and then taping the whole thing back together with the Home depot sprayer on the end of this kludge. Any better suggestions?
