Good Day! I have a 2020 Wonder MB. After emptying black and grey tanks I noticed dripping from where the macerator connects to the black plastic pipe. Is there some sort of seal/ o-ring that needs attention? Or is it one of the dump valves not closing completely? Please advise if anyone has experienced this problem. Thanks in advance.
Sounds like one of your dump valves is not closing completely, but you should not have any dripping from that area. What may have happened is that one of the bayonet tabs could have broken off, allowing the leak.
On some macerators the adaptor on the macerator with the tabs can be unscrewed and replaced. On some it’s part of the macerator.
The dump valves do need periodic lubrication and seal replacement.
Thanks Harry. Can the dump valve seals be replaced or do I need to replace the entire valves? How do you lubricator the seals. I checked the tabs on the macerator adapter and they look fine. Is there a seal where the adapter connects to the piping?
The valve seals can be replaced, kits are sold for that purpose. There are additives to pour into tanks, supposed to help, or take it apart, clean & lube.
I believe there is a large O ring to seal the tab connection.
Thanks for your help.
