Description
This Low Profile Bottom Drain Assembly with 3/4" Barb Connection, Black Finish, and 1-15/16" Face Width serves as a direct replacement drain fitting for multiple hot tub and spa brands. Designed to repair cracked floor drain fittings, this complete kit allows for straightforward installation by applying silicone sealant and securing the new face plate into the existing floor opening. While this kit includes the full body assembly that sits beneath the spa floor in the foam insulation, most repairs only require replacing the visible face component that threads through the opening, as this is the part most susceptible to edge cracking and damage.
The 3/4" barbed connection ensures secure hose attachment, while the low-profile design maintains proper water flow and drainage. The black finish blends seamlessly with most spa interiors. Compatible part numbers: 21400196, 640-1620. Ideal for fixing bottom drain leaks and cracks in Cal Spa and other hot tub brands.
Note: Silicone sealant kit available separately for complete installation.
