Review on Nelsen BT 1833 GRID Plate: The Ideal Choice for 18X33 and 18X40 Pools by Ken Beasom

The original grid in my softener's brine tank literally fell apart after almost four decades of service. This replacement is a much stronger poly plastic deck made from the same material as the tank so should last forever. It works and fits very well after some work. First, there are a few dozen perforations on the deck that were not formed. This probably won't be critical to its performance, but I drilled them to give the deck a fully perforated configuration. Second, the four "legs" positioned that held the deck off the bottom of the tank, the deck about an inch lower than the one it replaced, so I raised it with some sort of PVC pipe. Installing "stands" under these legs to provide the same amount of brine that will be below deck as before. Finally, the 4 inch diameter hole in the side of the deck was missing. It had to be large enough for the float valve riser to pass through. I cut the riser wall a few inches so it compresses enough circumferentially to squeeze through a 4" hole in the deck and provide the necessary support for the float valve assembly. I ran about 4 regeneration cycles on the softener and the brine tank appeared. work satisfactorily.
