Hughes Autoformers 30A Rain Cover
Provides immediate pressure and helps reduce water pump cycling.
If you have the stock Maxxair fan with the clip mounts, this takes all of 2 minutes to install.
We use this in our RV shower to stop hair from going into our HEPVO valve (under the shower).
We have one of these attached to the inside of our basement doors (both sides) to hold disposable rubber gloves.
