@MPCavalier I have a certain set of skills, describe the problem.
@CanisPundit
My question is...
Is the blockage in the hose actually the drain hose check valve OR did the round part of the tub's check valve break off - and get lodged in the drain hose? What should I feel inside the pump end of the drain hose? Thanks for any guidance.
@MPCavalier I’m in agreement with the broken part being an additional choke point. Removing and cleaning the hoses (ream, degrease, unblock) is my suggestion. And assure the disposal inlet is clear. The scary thing being the potential for fragments being inside the pump. And of course clean or replace the filter. Good luck in your mission. More times than not doing it yourself gets the job done sooner than tracking down someone to do it for you.
