A:AnswerIn order for them to install it you have to buy the hoses with it. Although if you already have the hoses, the delivery guys might be nice and install it for you since it doesn't take much time. They also will take away your old washer.
A:AnswerDid you run water through the hoses into a bucket to remove air from them? I believe that the machine has a minimum water pressure requirement but I'm not sure how much pressure is needed or how to measure the pressure coming out of the hoses. Also, calibrating the machine before use is recommended and the manual explains how to do so.
