I yanked the Bristol 1.5" waste water valve and quickly discovered the reason for the leak. The left hand seal was missing
. After an extensive search on the WEB, I could only find one source for 1.5" Bristol seal kits and shipping plus a small order fee would have been close to $30.00. No way!
Has anyone replaced their 1.5 inch Bristol gray water valve. Will a Valterra 1.5" fit..they seem more plentiful than Bristols.
