No ned to cut anything. Our plumbing was attached to the filter housing with 1/2-inch female fittings. We took the filter housing and bracket out and use the male pvc coupler to join the 2 pieces of plumbing from each side of the filter together. Filter housing could be put back in by removing coupling, putting bracket back, hanging housing on bracket, and reattaching plumbing. If you do use a coupling, be sure to use some teflon tape. I should add that these were screw-in fittings,made it all really simple.
