Thanks DWZM, I think I can just kinda put it together one piece at a time and compensate for the sockets in the fittings when I cut the PVC, since its a small tank, it shouldnt be an issue as most of the plumbing is fittings anyway lol... Just small bits of pipe to actually connect one fitting to another.

I'll email my self pics of my fittings real quick and post what i've got going on.

Post bump

The above is the most useful suggestion here IMO.

lubricating will interfere with cementing, and dry fitting will never be accurate. Carefully cutting square and measuring accurately will get you closer than anything else suggested. Repeating - dry fitting is NEVER accurate, and lubrication is going to mess with the cementing process

So here's the plumbing pics... One is a pic of just the pieces laying out, the other is a pic of the parts just laying down in a mock up of their actual layout... then i just posted a pic of the bottom pane of glass for my external trough. 3 bulkheads for the bean animal drain system!

YAY!

What do you think?

While the joint is considered an "interference fit" joint I would not go as far as saying it is "high tolerance"

The socket (female) portion of the joint is tapered, the male portion is not. While we can consider the fit an "interference fit" and many manufactures list the joint as such, it is more akin to jamming a round peg in a square hole

When I think of "interference fit" I imagine a joint where both the male and female fittings are tapered to the same high tolerance or a parallel fit that requires one part to be expanded (or contracted) to fit the joint. A morse taper quill and arbor (tapered interference fit) or a bearing on a motor shaft (parallel interference fit) are examples.

Not trying to argue, just kinda laughing at how poorly PVC pipe tolerances really are.

Quote:
Well the "Interference Fit" combined with the solvent is what allows PVC to create a sold bond/connection. When you apply the solvent and push the two pieces together the high tollerance is creating friction between the two pieces which causes the PVC to actually melt.
Nah I would submit that in practice.... the solvent melts the PVC. The soft PVC can be easily pushed deeper together where the tight fit displaces the softened pvc and solvent mess. The "friction" has little to to with the fitting of the joint and instead the solvent, PVC solids in the cement and tight fit allow a fairly uniform high surface area weld.

Does a rock fall to earth or is it pulled to earth

I'll dry fit deep enough so it doesn't fall off and I'll mark the pipe and fitting, glue and move on. I won't cut all the pieces at once but go joint to joint. Just spend time taking in account fitting depth.

+1 for going piece by piece

I dry fit most of it but left extra room knowing that the solvent would allow a closer fit than dry. I did have one issue when it came to the returns, my cross pipes were too short after glue and I had to cut and splice to make it fit. it sucked, but ended up working. but for the most part, I cut and glued each piece then moved on. the tank mains are 2" and the CL is 1.5"



clear cleaner and clear glue wont make a mess

My concern is that the plumbing is supported by its own joints and the pump. There really should be support hangers to carry the load.

The non removable check valve worries me.

Did even notice the CV... I certainly hope that has NOTHING to do with flood prevention.

yes it is non removeable, but will be removed in the near future and replaced with a better system. the sump can handle the full siphon of the tank to the inlets.

Plumbing is supported but cannot be seen in the photo.

ive always like the blue. lets me know I got it good.
