We've had this 2nd pool since 2013 and I've replaced the multiport valve 3 times now. I'm waiting on the 3rd to arrive, but am wondering if there is another brand that is compatible? The one we have is the WVS003, 1.5", locknut. I'm willing to replace hoses too if need be. This replacing it each year is NUTS. We had a Hayward before with no trouble, but moved and couldn't take it with us.
