New pool owner here. I recently replaced my old pump, which had a leak in the housing. All three pieces were leaking: pump, filter, and heater. The technician said it looked like it had been due to freezing, which did happen last year, but I had run it May -December without issues. The new pump is 1.5 hp, replacing a 1 hp pump. The pool store did help me with the power for the size of my pool, so that should be correct, however we never discussed the filter. Now that I am researching the filter, the website says it should not exceed 40 psi. I have no idea how many psi this pump is. Also please note that where the lid blew off, I am pretty sure there was already a crack. The threads are intact, and the lid created a semi circle where there was a smaller hairline crack before. I am wondering if I can just find the lid and screw a new one on? Seems that would be the cheapest. However I have to figure out this psi thing. The pump is a Harris 72786 pro force max inground pool pump with 56Y frame, 115/230 V, 1.5 hp. The filter I took a picture of, since that is existing and I don't even know the brand name. Any help is appreciated! Thanks so much.
