When the bowl starts draining down between flushes, this is the worn part behind it. It's the genuine part 31708, one seal per package, and it's a quick, inexpensive fix.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf your Aqua-Magic V toilet won't hold water in the bowl anymore, this blade seal is almost always the culprit. It's the seal that sits against the flush blade at the bottom of the bowl, and it's what keeps water where it should be between flushes. Over time it dries out, cracks, or gets chewed up by mineral buildup. Then you get that slow drain-down that lets tank odor creep back up into the bathroom.\u003c\/p\u003e\n\u003cp\u003eThis is the genuine Thetford replacement for the Aqua-Magic V permanent RV toilet, part 31708. One seal per package. It drops into the same spot the old one came out of, so there's no special tooling and no trip to the shop. If you can get to the base of the bowl, you can swap it in a few minutes.\u003c\/p\u003e\n\u003cp\u003eWe'd keep a spare in the RV or on the boat. It's a cheap part that saves a lot of grief when the old one finally lets go.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eGenuine Thetford blade seal for the Aqua-Magic V permanent toilet, part 31708\u003c\/li\u003e\n  \u003cli\u003eRestores the bowl's water seal so it holds water between flushes and keeps odor down\u003c\/li\u003e\n  \u003cli\u003eSingle seal per package\u003c\/li\u003e\n  \u003cli\u003eDrops into the factory location, no special tools needed for the swap\u003c\/li\u003e\n  \u003cli\u003eDirect OEM replacement that keeps your toilet working the way it did new\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Thetford Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does this blade seal do?\u003c\/summary\u003e\n    \u003cp\u003eIt seals against the flush blade at the base of the Aqua-Magic V bowl so water stays in the bowl between flushes.
