My 3" Valterra Black Tank Valve Leaks - Needs New Seals
Question:
I just removed it and there is a 1/16inch on the sides of the blade. How can there be a gap along the sides of the blade and it still seal from leaking through? The pictures on your website also show a gap on each side. Please explain how it is supposed to seal. My valve just has hard plastic the the blade glides on. There is no rubber seal. It appears according to your pictures they are made that way. I dont want to buy a new one and still have gaps where raw sewage can leak through. Luckily the cap seals great but it is a mess at the dump station!!

As a clarification, all valves, including the # T1003VPM, include seals, as pictured in picture 10 on the product page.
However, I can see that your 3" waste valve is missing it's seals. I would not buy a new complete valve when all you need are the replacement seals. Valterra makes two Replacement Seals & Hardware kits for their valves. The # T1003-7VP is for "old style" Valterra valves made prior to 2000, and # T1003VPM is the current style that fits Valterra, Bristol, Bladex, and Anonda valves.
Unless someone installed an old style valve on your 2019 Winnebago, you probably have the new style.
With your defective waste valve draining off the liquids from your black tank you may have some solids left behind that may need some encouragement to move along. You should consider the Camco # CAM40094 "Swivel Stick" tank rinser. You will want to flush and drain a few times before taking that valve apart! If it were me the fill for flushing would include a water/bleach mix for some level of sanitizing.

Les, You caught my attention when you were talking about the older style valve. A friend of mine was helping me replace the seals on a 1 1/2 inch grey valve. But the seals turned out to be thicker than the seals that were in the valve. Consequently he couldn't get it to work properly and wound up putting the old seals back in there to close it up. Of course now it leaks worse than it did before. Are the older style seals thinner than the new style seal? Can you give me the link for the holder 1 1/2" seal kit please. The valve is 1 1/2" Valtera cable My 5th wheel is 2006 Dutchman. Thanks!
