We have two Raritan PHII toilets and an Electro Sans plus a small holding tank - which we do not use.
Lately we are getting a bad smell while flushing. These are salt water toilets.
I performed treatment recommended by Raritan using Muriatic Acid. No real improvement. Then I got idea that perhaps there were dead critter remains inside the toilet causing the smell.
I emptied the bowl and filled it with fresh water and Barnical Buster. I disconnected the inlet hose to the toilet and connected it to a small pump in the bowl. This circulated the BB mix through the innards of the toilet. See picture
I let this run for about thirty minutes. There is some improvement but not much. I did the wet rag test on the hoses and the smell isn't coming from them.
Anyone have any other ideas?
