Drain Repair Cost Calculator
Drain repair materials cost $16 to $75 per drain in 2026, including PVC drain pipe, fittings, PVC cement and primer, drain strainer, and plumber's putty. Simple drain replacements need $20-$40 in materials while full drain rerouting costs $50-$75+. Enter the number of drains for an instant breakdown.
What materials do you need for drain repair?
Drain repair requires five core materials: PVC drain pipe (Schedule 40 DWV in the diameter matching your existing drain — 1-1/4" to 4"), PVC fittings (elbows, tees, couplings, and adapters to connect new pipe sections), PVC cement and primer (the chemical welding system that permanently bonds PVC joints — always use purple primer first, then cement), a drain strainer or basket (the visible piece that catches debris at the drain opening), and plumber's putty (seals the strainer to the sink surface to prevent leaks). For repairs involving transitions between pipe materials (e.g., connecting new PVC to old cast iron), you'll need rubber fernco couplings ($5-$15 each) with stainless steel band clamps.
How do you properly cement PVC drain pipes?
PVC cement creates a permanent chemical bond — there is no undo, so dry-fit all pieces first. The correct process: First, cut pipe square using a PVC pipe cutter or fine-tooth saw, then deburr the cut end with sandpaper or a deburring tool. Second, dry-fit all pieces to verify alignment and mark orientation with a pencil line across each joint. Third, apply purple primer to both the pipe end and the fitting socket — primer softens the PVC surface. Fourth, immediately apply PVC cement to both surfaces using the applicator in the can. Fifth, push the pipe fully into the fitting with a quarter-turn twist and hold for 15-30 seconds. The joint reaches handling strength in 5 minutes but needs 2 hours before running water and 24 hours for full cure. Ambient temperature below 40°F requires extended cure times.
When should you call a plumber vs DIY drain repair?
DIY-appropriate drain repairs include: replacing a P-trap assembly under a sink ($5-$25 in parts, 30 minutes), replacing a drain strainer or basket ($3-$30, 20 minutes), and fixing a single leaking PVC joint in an accessible area ($5-$15, 1 hour). Call a plumber for: any repair behind walls or under concrete (requires demo and permits), main sewer line issues (root intrusion, bellying, or collapse), any work involving cast iron pipe (requires special tools and expertise), code-required work like re-venting or adding cleanouts, and any time you smell sewer gas (indicates a more serious venting or trap issue). The cost of a plumber for complex drain work ($200-$500+) is far less than the cost of water damage from a failed DIY repair.
