Road Shower 4 on/off elbow. Turn the black handle to turn the water off. You can remove the hose while water is in the tank. This also works to upgrade a Road Shower 1 or 2.
Camping tip: Use the black handle to regulate water pressure. 65 PSI might be too much for a shower, but just right for blasting mud off a mountain bike. Open full to the horizontal position for max pressure. Turn it towards off to dial back the pressure.
This elbow can be added to the opposite end of your Road Shower 4. This is useful for adding an accessory such as the optional shower head. In addition, it is useful so that you don’t have to worry about which end of your Road Shower is on the downhill side. Move the hose to either end easily.
Add some white plumbers tape to the seals prior to install.
