shower drain
DS….. In a 2018 coach, I’m guessing you have a HEPVO valve, as suggested by LtDan. If your shower floor is less than ~5 inches above the base floor, that would tend to confirm the HEPVO. DO NOT use that barbed clean out tool!
My DS is older (2002) so I don’t have to deal with a HEPVO valve, but this same process will be acceptable for you. I buy two bottles of the Mr Plumber brand drain cleaner at Walmart. I use the kitchen sink as my indicator. When that gets a little slow, I clean them all. Or, every 6-8 months regardless. At bedtime I pour about 2/3 bottle down each of my three drains,— kitchen, bath sink, shower. I leave it overnight and flush all three in the morning. This has worked for me for almost 10 years.
