A:Answer Hi sallie, thanks for your question and for your interest in model SHXM88Z75N. Per the installation manual, the following materials are needed: 1) Elbow connection with 3/4” female hose threads on one end and fits your water supply line (copper tubing, compression fitting, or braided hose) on the other. 2) Hot Water Supply Line - Minimum 3/8″ O.D. copper tubing or metal braided dishwasher supply line. Only needed if house water supply line is not sufficient. 3) Shut-off valve and fittings appropriate for hot water supply line (copper tubing/compression fitting, or braided hose). A list of the tools needed can be found on page 6 of the installation manual as well.
