Im new here to the forum. I have a older (2005 maybe) master spas legacy tub that i inherited The two speed pump went bad so i ordered a new one from spa depot. The old pump wet end/volute discharge had a small "port" on it that a small maybe 3/8" hose hooke
d up to. I believe this hose then went to one side of one of the jets and maybe teed in with the other smaller diameter tubes (each large jet has a small diamter hose and a large diameter hose going to it). The new pump I ordered is same ratings but does not have the "port" for the smaller diameter tubing on the volute/discharge of wet end. What should I do? What is the purpose of this smaller diameter hose that hooks up to discharge side and why cant i seem to find a identical one online? spa depot has been of no help so far. Any thoughts would be appreciated greatly as there are no spa techs in near vicinity or I would have them doing this
