This is for round units WITH DIVERTER SEALS only!!!! Don’t buy if you not sure what you need contact me first. If you’re going to work on your own unit, I recommend you replace the O-rings and seals They might still look good, but if they’ve already been used, they have already crushed from original installation. You should never reuse any of the O-rings on any of the pool bot units. Happy bidding!!
