We highly recommend this kit for a proper water pump installation. Rigid pipes, like PEX or copper should not be plumbed directly to your water pump.
These 36” high-pressure flexible hoses are designed to fit between the pump and the rest of your plumbing system to reduce unwanted rattling and plumbing vibration noises.
The kit comes with two 1/2” MPT pipe nipples for added convenience for a variety of systems.
