Clogged Marine Head
Just recently purchased a used 35 foot sailboat. When sailing her home, I noticed that I could not get water to pump out of the head. I have no problem pumping water in. And yes, I switched the lever to dry when I tryed pumping it out. I believe that it is clogged as tiny bits of toilet paper have starting floating back into the bowl. The holding tank is completely empty and there is no Y-valve that separates the holding tank from the overboard discharge.
The question is: "Can I use draino or a snake on a marine head?" Are there any other suggestions besides having to take the thing apart?
Thanks for you help.
PS. The plumbing is not PVC pipe but marine grade plubing hose.
