Hi there, purchased a Jacuzzi Force pump from you all last month and now the sand filter has a leak. I have to replace the top mount valve because the leak is coming from a "hair line crack" in the threading. Here are the numbers I got off the valve tag: Jacuzzi 39263100 Model: DV Assy 7-Pos 1-1/2 Npt Tri, serial number B7-0000365 Date: 02 December 2011. Is this the correct replacement that I need? I'll order as soon as you let me know. Thanks.
