Charlotte Pipe FAQ: Fitting Dimensions, PVC DWV Hub Hub Repair Coupling, 14 Pipe Wrench, 824 Aluminum Pipe Wrench, and Hole Saw for 1 1/2 Pipe

Charlotte Pipe and plumbing tool FAQ for buyers

I handle facilities purchasing for a 140-person fabrication shop. I manage all MRO and plumbing supply ordering—roughly $180,000 annually across 11 vendors. I report to operations and finance. When I took over purchasing in 2021, I assumed Charlotte Pipe was just another PVC brand. Then I had to reconcile a DWV submittal package, a 14 pipe wrench order, and a hole saw request for 1 1/2 pipe—all in the same week. If you typed charlotte-pipe into a search bar and landed here, these are the questions I actually ask vendors now. Specs first. Brand second.

What is Charlotte Pipe known for?

Charlotte Pipe and Foundry is a U.S. manufacturer of pipe and fittings, including PVC DWV, CPVC, ABS, and cast iron soil pipe products. For B2B buyers, the useful part is not the logo. It is the published dimensional data. Charlotte Pipe fitting dimensions are available in the technical catalog at charlottepipe.com, so you can check hub depth, lay length, outlet size, and standard compliance before you cut a PO. This was true 20 years ago when local supply houses were the only reliable source. Today, the catalog is online, but the specs still matter.

How do I read Charlotte Pipe fitting dimensions without guessing?

Do not order by nominal size alone. A 1-1/2 in fitting has a specific outside diameter, hub diameter, and lay length. For PVC DWV, the fitting standard is ASTM D2665. Pull the Charlotte Pipe catalog page for the exact part, then verify three things: pipe OD, hub depth, and fitting pattern. If the submittal says a 1-1/2 in hub x hub coupling, confirm the actual pipe OD is 1.900 in for Schedule 40 PVC DWV. I keep a printed page for common fittings (note to self: update it when we switch suppliers). Check the OD, the hub depth, and the standard. In that order.

What is a Charlotte Pipe PVC DWV hub hub repair coupling used for?

A Charlotte Pipe PVC DWV hub hub repair coupling is used to splice into an existing DWV line. The repair coupling usually has no internal stop, so it can slide over both pipe ends. That matters when you cannot flex the pipe or when a standard coupling with a center stop will not fit. You cut out the damaged section, dry-fit the repair coupling, then solvent weld it. So glad I checked this before approving a PO. Almost ordered a standard coupling, which would have stopped halfway and left a gap. The upside was saving about $1,800 with a cheaper part. The risk was a callback on a commercial DWV line. I kept asking myself: is $1,800 worth potentially failing inspection? No. For 1-1/2 in PVC DWV, verify the 1.900 in pipe OD and the DWV rating.

What should I check before ordering a 14 pipe wrench?

A 14 pipe wrench refers to handle length, not jaw capacity. Before you order, check the jaw opening, the pipe material, and the handle material. A 14 in wrench is often enough for 1-1/2 in PVC DWV fittings, but it may not be enough for stubborn metal pipe or rusty no-hub work. Weight matters too. The numbers said a 14-inch wrench would cover 90% of our calls. My gut said the crew would still grab a cheater bar. We bought one 14 and one 24 in aluminum. Callbacks dropped. If your crew works overhead, aluminum is usually worth the extra cost.

Is a 824 aluminum pipe wrench worth it?

A 824 aluminum pipe wrench is typically a 24 in aluminum model with a wider jaw capacity than a 14 in wrench. It is worth it if your team does repeated large-pipe work or overhead work. Aluminum cuts weight, which reduces fatigue. It does not make a bad technique safe. Check the exact jaw capacity and whether the wrench is rated for the pipe size you actually touch. I have mixed feelings about premium aluminum wrenches. On one hand, they cost more. On the other, I have watched a 4-pound difference turn into fewer dropped tools and less fatigue. Speed, weight, capacity. Pick two if you are buying budget.

What size hole saw for 1 1/2 pipe?

It depends on the pipe material. For 1-1/2 in PVC DWV Schedule 40 pipe, the outside diameter is 1.900 in according to Charlotte Pipe's technical catalog. A 2 in hole saw is tight. Use a 2-1/8 in hole saw for normal framing clearance. For 1-1/2 in copper, the OD is about 1.625 in, so a 1-3/4 in or 2 in hole saw works. For 1-1/2 in no-hub cast iron, measure the pipe and the coupling sleeve; the pipe OD is near 1.900 in, but the coupling may need a 2-1/4 in hole or larger. The '2-inch hole saw for everything' thinking comes from an era when pipe clearances were less regulated. Today, firestop and structural holes need a plan. Check local code for hole size and protection plates.

Where do I find official Charlotte Pipe catalogs and submittals?

Start at charlottepipe.com. Download the technical catalog and the submittal sheet for the exact fitting family. Attach the PDF to the purchase order and the receiving packet. Do not rely on a distributor's shorthand description. I verify the revision date (mental note: save the PDF with the PO). If the catalog does not list the dimension, request it in writing before you order. This is especially important for repair couplings and cast iron no-hub products.

What mistakes should purchasing teams avoid?

Ordering by nominal size only. Assuming all 1-1/2 in pipe has the same OD. Mixing DWV fittings with pressure fittings. Buying a 14 pipe wrench without checking jaw capacity. Skipping the submittal review. In 2022, a vendor could not provide a proper invoice—handwritten receipt only. Finance rejected the expense report. I ate $2,400 out of the department budget. Now I verify invoicing capability before placing any order. That rule has saved more time than any price negotiation. The client sees the finished plumbing. A failed inspection or a leaky repair coupling is a brand problem for the contractor and for us. If you buy Charlotte Pipe fittings or a 824 aluminum pipe wrench, make the spec sheet part of the PO. Done.
