Review on 🚽 Roebic RVM-Q 32 Oz RV and Marine Holding Tank Treatment by Sam Hawj

Revainrating 1 out of 5

Ruined my marine toilet joker valve

I gave this one star BECAUSE it ruined my JASCO marine toilet joker valve. Luckily I had a replacement with me and I changed the Joker on the quay AFTER the tank was completely empty (fill up several times after fresh water). Not sure if pouring into the evacuation port is next to hit the joker valve. The first time cost me $20 (for a new valve). This chemical acted on the rubber joker valve, causing it to swell until the liquids were pushed back into the bowl (no matter how much you pump out of the bowl, it will slowly refill). I'm not sure if the product did what I wanted it to do. I have a 20 liter tank that fills up after a few washes. It's been like this since I bought the boat. I understand there are solid particles at the bottom. Time will tell if this has helped OR I need to treat a few more times.

Pros
  • Sewer chemicals and cleaners
Cons
  • Nothing
