Replacement Tubing

SO frustrating that this is only one. Very vague description. The directions in the pump says ‘replace’ parts wvery so often. But they sell only one? This mis understanding could easily be fixed by adding ‘single’ to the description. Same with the back backflow preventor. Seriously SO Frustrating. Not to mention i’ve spent over $40 in shipping trying to get two backflow preventers and two tubes to my house. Shame on me for the same mistake twice I suppose.

Frustrating that it does not come in a two pack
