Hi there - Our 1.5 hp pool motor/pump died and our local pool supply recommended going to a 2hp. Sounded ok.....the circulation in pool is fantastic! HOWEVER, now after 1 month with new pump our Hayward Pro Series S180T has started leaking.....first at a seam, now today, also from the head. We see the max working pressure for this filter is 40. Can the pressure really be at 46? Is the gauge broken? After hours reading on forums this morning.....I see people saying their "clean filter" psi being around 10. The pvc plumbing is all 1.5".....our local pool place said nothing about plumbing needing to be changed to 2"pvc. Not sure what we need to do. Ready for new filter, don't know what size to get. Should we just turn it off due to the crazy high pressure? Hope someone can guide us!!
