  • Schedule 80 DWV pipe

    Another project we're looking at calls for 4" schedule 80 pvc in a parking lot which is roughly 3 feet deep for about 60ish feet to the manhole. The under slab is schedule 40 ABS. I can find schedule 80 pressure pipe and fittings but not dwv fittings. Any ideas?

    BTW, We have rfi's in questioning the sch of the pipe. the engineer was an idiot imo. We're building to ipc. The sewer line is crossing an existing water line and the prints call for a rebar cage and concrete 5' on each side of the C/L. Where in the heck is this code??!!! This is why we roll up blue prints.....to hit engineers over the head with them.

    I'm not sure there are Sch. 80 DWV fittings. You can call Charlotte and/or get test & installation specs. to submit. Might be all you need.

    The "rebar cage" seems to be from the mind and ego of an engineer.

    But in fairness I'm not looking at the prints either. What kind of water line is it? Small 3/4" copper or 6" plastic of some sort?

    If it's a big line it may not be bad to cover your bases with a cage support.

    If not, seems knuckleheadish.

      When ever drainage is over potable. Potential cross contamination could in theory happen.

        Hey Ben, They make sch 80 fittings just brace yourself when you get the pricing on them. Just seen paperwork on a 4" sch 80 long sweep st 90 that a local industrial plumbing company brought back to try and get credit for $95 a fitting and they had 12 of them. Make sure if you do buy some that you check on the return policy

          Mike, what company makes them? JC, It's a 4" sewer line going over a 10" ductile iron main. According to IPC, as long as your sewer line is rated for interior use(no clay), the sewer and water can be in the same trench with no seperation.

                So these kooky military engineers are sending you these butterfly valves cause they say "Or equivelent".
                You look at hpde fuseseal or something more common than sch.80 DWV.

                For future renovation

                    Yes, but what is the "intent" of that code or the interpretation. It may be for intended for the one buildings water & sewer.

                    Is the 10" water main only supplying this building? And the DWV only for the same building?

                    If not then code interpretation or local jurisdiction could exclude the IPC interpretation you quote so as to protect others.

                        Spears Sch 80 PVC Fitting Price List.

                        My old company sold Spears fittings for years and they are a very reputable company if you're not familiar with them.

                          Same with UPC (2006). See Section 609.2. But, you do need enough separation to allow for repair.
