I inherited a 25 year old Blue Falls tub, It had froze. To make a long story short, I have fixed all the tube leaks, rebuilt the pumps, new heater element, and replaced the PRESSURE SWITCH (basic design two contacts). That was over 4 years ago, and have enjoyed using it. but has had a reoccurring flo isuue I had replaced the pressure switch with a Tecmark, all metal switch as it screws into the heater element. Made sense to me. it lasted only 1 year before it started glitching. I replaced it with a Tecmark plastic base. It only lasted a year and a half before glitching. Right now I dont want to spend another $50 on a sensor that will fail in a year?!? is there another manufacture of QUALITY pressure switches??
