Just installed a Jabsco head , cleared out lines and replaced some . I removed the 25 yr. old Raritan PH II , it was still working but getting hard to turn the flush/dry dial also needing a sip of veg oil almost every day . I could have rebuilt it , but it was time for new .
Anyhow the reason for this post is I cleaned the the vented loophttps://www.westmarine.com/buy/forespar--marelon-vented-loop-1-hose-barb-7-h-x-9-w--P011_332_003_012?pCode=7363187&mrkgcl=481&mrkgadid=3085587800&cm_mmc=PS-_-Google-_-GSC%2520-%2520Product%2520Type-_-7363187&product_id=7363187&adpos=1o2&creative=108421552684&device=c&matchtype=&network=g&gclid=EAIaIQobChMI0OKmg-am3AIV0oZ-Ch1XNgJhEAQYAiABEgIDcfD_BwE also dissembled the vent and cleaned it , all went back together nice . Then later I noticed a rubber washer that had a clear plastic disk over the hole , outside where I was doing the cleaning . Was this washer part of my vented loops' joker valve ?
