When working behind the UDC on some new electrical modifications, I noticed the hose that is connected to the output of the water pump to a tee in the cold water line was bulging. This piece of hose looks identical in type to all the others behind the UDC and is about one foot long. I planned to change the hose out (it did have screw on type clamps). I didn't have any of the proper size hose at the time (1/2 inch inside diameter). Later in the afternoon, the water alarm for the basement went. Yes, I did install one as recommended on the Forum. I looked into what was going on and found that the hose had split. It has about a 1/2 inch long gash in it. After getting the shore water turned off fast, we made a trip to Home Depot in a hurry. I found Watts braided vinyl tubing that is 3/4 in OD and 1/2 inch ID. It didn't have any pressure specs but we found that it may be 150 PSI according to Watts web site. I replaced this one foot long piece of hose and hooked it all back up. This morning, I found a slight drip from one end and that the new hose seemed to be bulging a little. HELP! Has anyone had this or similar problem and what is the solution.
