CHARLOTTE PIPE 4 x 3 DWV Flush Bushing (30 Unit Box) - Durable DWV

In this review the CHARLOTTE PIPE 4 x 3 DWV Flush Bushing is evaluated for plumbers and contractors who need a dependable, easy-to-install white DWV fitting in bulk. The bottom line: this 30 unit box is a practical choice when projects require consistent, lightweight fittings for sanitary drain, waste, and vent or sewer and storm drainage applications, provided the system is not used under pressure or exposed to temperatures above 140 F. It is a straight-forward, no-surprise component that performs as expected in standard DWV installations.

Key Features

• DWV compatibility: Designed specifically for sanitary drain, waste, and vent systems, the fitting ensures correct connections for non-pressure drainage work.
• Temperature limit: Rated for use where systems will not exceed 140 F, making it suitable for most residential and light commercial drainage setups.
• Not for pressure use: Clearly intended for gravity drainage and venting, avoiding misuse in pressurized plumbing runs.
• Lightweight installation: The PVC material keeps individual pieces light and easy to handle, speeding repetitive installations on site.
• Bulk pack: Supplied in a 30 unit box, this helps keep projects on schedule by providing multiple identical fittings without frequent reordering.
• Made in the USA: Manufactured domestically by a long-established company, which may be important for buyers preferring US-made plumbing products.

Who It's For

This product is aimed at professional plumbers, HVAC technicians, and general contractors who install or maintain DWV systems and need reliable, uniform fittings in quantity. The 30 unit box suits jobs where multiple identical flush bushings are required, such as multi-bathroom remodels, new builds, or large repair jobs.

Homeowners doing light DIY drainage repairs may find the single-piece use helpful, but those needing fittings for pressurized lines, high-temperature industrial systems, or specialized materials should look for alternatives rated for pressure or higher temperature service.
