WashR DUO | What is the RED cap installed in the valve manifold?
The red cap installed in the valve manifold of your bigboi WashR DUO is a shipping plug, designed to protect the pump during transportation. It must be removed before first use.
Before operating the unit, replace the red shipping cap with the black breather cap provided in your parts bag. This breather cap allows proper ventilation during operation and is essential for maintaining optimal pump performance and preventing pressure build-up.
Important:
Operating the unit with the red shipping cap still in place may cause damage and will void your warranty.
