Attaching Black tank Valve assy.

My new gray and black tanks are coming next week.I ordered a Valterra valve assy.with two gates.One for BT Dump 3" and a 1.5" for gray.
How do I attach the valve assy. to the tank? Hesitant to glue if I can clamp.

The ploy tanks have to have the fittings spun welded to the tank or are formed with them. My grey water tanks are Poly but I have a place just a couple of miles from where I live that will spin weld the fitting on of me. The supplier of your tanks should be able to do that for you.

I had my black water tank made of ABS so that I could glue my own fittings on. It came with a fitting that can be glued to the bottom that will accept a 3" male NPT stub that I can glue a dump valve fitting to.

I wonder if Steve is not talking about the fittings specifically but the method of connecting the valve s to the fittings? I've wondered the same thing. I have mine configured with glued fittings(not glued yet) but have seen where some use a rubber fitting with clamps. I could envision having to replace the whole tank in the event of a problem if using nothing but glued.

I must have been having a dyslexic moment!I am having the inlets and vents spin welded.I am wondering about the Valterra assy. that has the gate blades used for emptying the tanks.It has to be attached to the 3" tank outlet to empty the tank.
How is this part fitted?

Ok lets start over again, The inlet and exits, do they have internal threads or are they just plain 1 1/2" and 3" stubs?

If it were me I would use a high quaility reinforced hose that the inside diameter matches the outside diameter of the stub. That should be 3". I would also use good clamps like the one shown below.

Steve,
I am going to order my Ronco tanks tomorrow. I am using the 17H for gray, and 18H for black. Were you able to glue the ABS fittings into the tanks? Also you said they gave you a pretty good deal on your tanks. Can you give me a ball park on your cost?
Thanks Steve

Can I help/watch?

Where are you buying the tanks from?

How are you fitting them on your Safari and are you taking photos?

Any chance of taking a look at installation in Rescue before you button it up, or can I help you do it (ie. practice on yours)?

Doing time in Folsom until end of the year with 1964 Safari in need of same mod.

I measured where I wantend the fittings ,sent a sketch and they roto spun welded them on at no additional.I just made sure I had the inlet and vent for the gray well into a cabinet area.When I made the brackets for the tanks(as they have a large lip to hold them)I was able to have a little adjustment room.I measured the black 3" hole from the back access door.In addition,before I cut the 3/4 ply for the area I cut 1/4 6.00 a sheet Luan as a template to mark the holes.They were very helpful.The only thing you would buy is pipe cement, 3" black Sched40 3" pipe,maybe a street elbow.For the gray you need a 3" to 1 1/2" reducer ,some 1 1/2 " pipe and assorted elbows to get to the valve assembly.The reducer and the elbow on the black dump are installed with silicon caulk and a band clamp.I used a Valttera assembly from PPL Motorhomes in Houston(about $30).11/2 in on on side and 3" on the other.It is adjustable.Got mine a hooked up and no leaks!!!It was a fun project.
I think I was at about $350 with shipping.Just tell them Steve Riley and Uwe Salwender use their tanks and referred you.Ask for Sheila and she will get you with the right tech people for any questions. Good Luck!
