Just completed a retractable hose reel python swap using the reel below found at a local Lowe’s. Pretty simple even without instructions, but maybe this will help someone.
Ames NeverLeak Wall Mount Hose Reel
Necessary Equipment
Phillips head screwdriver
2x zip ties
1. Remove the hose retraction stop from currently installed hose.
2. Pop off the two side panels.
3. Unscrew the 2 screws holding the middle/top panel in place.
4. Pull about 10-20ft hose out at a time, followed by loosening up the spring with the crank on right hand side by spinning counter-clockwise. Repeat until all hose is out.
5. Use a zip tie to hold the reel in a convenient position and avoid losing a finger. Plenty of options where you could stick it, just so it goes through the housing and reel.
6. Cut zip tie holding the factory hose to the reel, loosen metal hose clamp and remove hose.
7. Replace factory hose with python and basically just go through the previous steps in reverse. Be careful with that metal hose clamp though, I added a dab of hot glue on the sharp edges once fastened to avoid potential cuts and nicks.
