This essential component ensures a secure, leak-free seal when draining or servicing your filter system. SPECIFICATIONS Technical Details Manufacturer Watts Model Number BB-DRAINPLUG Compatible Housing Big Bubba Series Material Durable plastic construction Function Drain valve plug Thread Type Standard Big Bubba drain fitting Purpose System drainage and maintenance Replacement Frequency As needed or if damaged INSTALLATION & USE How to Replace the Drain Plug Ensure the Big Bubba housing is completely drained and pressure is released before removing the old drain plug. Thread the new BB-DRAINPLUG into the drain port on the bottom of the housing, turning clockwise by hand. Tighten firmly but do not over-torque, as this can crack the plastic threads or housing. Test for leaks by slowly refilling the system and checking the drain port area. COMPATIBILITY Works With This drain plug is designed exclusively for Watts Big Bubba whole house filter housings. It will not fit standard 10-inch, 20-inch, or slim-line housings. Verify your housing model before ordering to ensure proper fit. 🔧 Keep a spare BB-DRAINPLUG on hand if you service your Big Bubba housing frequently. The threads can wear over time with repeated draining, and having a backup ensures you can complete maintenance without delay. Show more
