“Urinal drain pipes clog more than toilets and therefore can be smellier and costlier to maintain.”
I see no reason to believe THIS piece of excrement from CNN over any other POS they excrete.
it’s true..sea water and urine together create calcium deposits in pipes..a real PITA when underway. After being on the last class of subs that had them (585 class) the only way you can unclog them is large amounts of Citric acid. Put up with that for years on my last Fast Boat..USS Shark SSN 591.
