Has anyone removed black & gray water tanks on a U225 any tips or tricks I should be aware?
During our last trip there was a small almost like a condensation water leak .. it was there now it is not there. I am thinking to remove them to see what is going on and depending on condition fix or purchase new. I believe it was from the gray water tank ... but.
During that time maybe i can also add a third waste gate valve.
I already remove the carpet covered panel from the back side of tanks, where the level sensor cables attached. that is where the leak was.
Thank you,
AL

I'm starting to think about adding a third valve. Don't know which brand of connection I have, but it is white and larger than the orange that seems to be the standard now. We're going to Springfield sometime next week (Sam's shopping, mainly) and I thought I'd stop in at Camping World to see what's available. What I'd really like is something that will just attach to the existing pipe and will let me then attach the orange hose directly to that. Is something like that available? I don't need the sewer hose attached when the door is closed, but I don't want to block the access door either, since the electric cord has to come in there, and it doesn't like to bend when it is cold out (neither does my back).

It sounds like you may have a Thetford fitting, which is larger than the more common Valterra fitting.

When I added the third valve, I cut off the Thetford fitting and glued on Valterra fitting. My third valve is a twist on valve with a Valterra female fitting on the coach side and a Valterra male fitting on the dump station side.

Yup.  Thetford, I'm sure.  I used a Dremel tool to get the old thetford cut off, then bought 3 separate Valterra pieces from Amazon to put together.  A slip on fitting to glue to the black pipe, and then the valve itself, and finally, a fitting to take the twist-on Valterra for the hose.  Care is required to make sure you put it together so you can tear it apart and replace the valve part if needed in the future, and ensure the valve handle goes where you want it to when it is pulled (not in the way of something).

Here's a picture of what worked for me in my 2002.  See the exposed nuts for replacement, and the valve pull is out of the way of everything.

I haven't yet gone after mine with a saw and glue put, so I use a valtera to thetford adapter. Works well, but prevents me from closing the bay door with everything connected.

My recollection is that the twist on valve I used came with Valterra fittings on both sides. The input side is female, the output side is male. The body can be rotated to any position with respect to the alignment of the locking "grabbers" on the female side. The installation appears to be similar to Lang's.

 The only possible problem with mounting them side ways is the chance of "stuff" getting into the upper slide area and causing build up problems down the road. If it dries hard in there will make moving the "gate valve" difficult.

I bought a inline male/female Valterra valve. I had to take about 1/2" from both sides.(cut and re-glued) to get it to fit inside the door. Simple and pretty slick. I should have done this years ago!

Just finished my dump valve upgrade today.  Replaced the two existing valves (which were mounted horizontally by the factory) and added the 3rd valve.  Pretty easy to see why the black tank valve was leaking!

Did it take an odd connector size to the tank.

John,

If the above question is for me, I assume you are asking about the piping that connects the manifold to the tank outlets?  If so, the answer is: all the pipe you see is original equipment.  All I did was replace the valve bodies on the old valves, and added the 3rd valve by cutting off the old Thetford connector and glueing on the new valve.  Pretty simple, and easy access once the cover panels were removed.

Where are you getting the parts for this project? We're planning a Sam's trip later this week, so a detour to Camping World would be reasonable, but I don't see what I think I need on their site. I did find a Thedford to Valterra adaptor, but I'm thinking that adding that and then a third valve might be too much for me to close the bay door. I think it would be better to just cut off the Thedford fitting and glue on a new Valterra fitting.

Most camping stores and parts departments at rv dealers have the parts

Thanks, Red Tractor. I suspected as much, but when I couldn't find it on Camping World's website I wondered.

If you are in one place for a couple days for Amazon to get it to you, this is what you need. 

Cut off the old Thetford end, decide which way you want to position the handle pull, make sure the nuts will be accessible to replace the seals in the future, when sure of what you want, glue it on, enjoy.
