I am a single female college instructor who owns an old Portland style house in the historic Sellwood antique district of Portland, Oregon. The original house was built in 1903, but I have had extensive remodelling done by licensed contractors. However, both downstairs and upstairs new toilets trickle constantly and there seems to be a little debris that accumulates gradually in the upstairs tank reservoir; replacing plungers et al. does not fix the problem.
Can you help?
