I put together my tire cleaner foamers today. I used 1 1/2″ schedule 40 pvc pipe. Parts list: 1) 5 x 6″ pieces of 1 1/2″ pvc, 2) 5 x 1 1/2″ spigot to female hose thread 1/2″, 3) 10 x 1 1/2″ coupling, 4) 10 x scrubbers from Dollar Tree
I purchased all my plumbing supplies form http://www.plumbingsupply.com/ .
If you look at the second picture I did make one “SUPER FOAMER”. It might be the exact same thing but it is a “SUPER FOAMER” and not just a regular non-labeled foamer. I do not think my car wash could handle more then one “SUPER FOAMER”.
