Frequently Asked Questions

How do I know if my flapper valve needs replacement?

Common signs include weak or incomplete flushing, water draining slowly from the bowl, hissing sounds when flushing, or persistent odors even after tank treatment. If your 87 or 8600 toilet isn't holding water in the bowl or flushing with normal pressure, the flapper valve is likely worn.

Is this kit difficult to install?

Installation requires removing the toilet bowl from your RV and accessing the internal valve assembly. Most RV owners can complete this in 30-45 minutes with basic tools. Detailed instructions are included with the kit. If you're uncomfortable with the process, a mobile RV technician can install it quickly.

Will this kit fix odor problems in my bathroom?

Yes. A worn flapper valve prevents proper tank venting, allowing sewer gases to back up into your bathroom. Replacing the flapper restores the vent seal and eliminates this issue. Combined with regular tank treatment, this kit solves most odor complaints related to the toilet.
