Sealand - Flush Valve Replacement

[MACK C-85]

While dewinterizing I found that I had a broken flush valve on the toilet of my 2007 T-276SR. Here's what's involved in replacing it:

After turning off the H2O and opening up the drains to relieve the water presssure, you need to remove the cover:



Next you need to remove the two hoses from the valve. The supply hose has a threaded nut, and the discharge hose to the bowl pushes on and is held in place by a screw clamp:



Next you remove the two screws holding the valve in place:



You can see in the above photo where the plastic stem on the valve broke.

Here is a side by side of the new valve and the old one. Note the stem is now BRASS!!!!:



The new valve is screwed into place and the hoses reattached:


After reattaching both hoses, turn the H2O back on and check for leaks. Snap the cover back in place and you're back in service!!

Even with taking the pictures it only took twenty minutes.

Sorry for the quality of the cell phone pictures, but they get the idea across!!

You are right about the pics... They do get the point across!

Nice job! Expensive little part, but it's pretty hard to get by without it... I'm glad to see they made an improvement to it though, that's rare.

Yes @ almost $60 with MD Spendacrat taxes...it's pretty steep!! But, you're right, a convienient potty was one of the bennies of the coach!! Anyhow, yes it is good to see the brass on the working part that gets the most strain, even though they made the vent (vacumn breaker??) plastic!!

Yup, that sounds about right. Back when I first got this trailer, I investigated what it would take to add in the auxiliary sprayer to the toilet that they stopped including in 2006. In order to add that, it would be simple since they have make twin toilets with the sprayer, so it just involves changing that water valve and adding the hose/sprayer. But still, it would have cost me north of $50 to do that, which just wasn't that worth it! Maybe some day if the valve does like yours did.
