For your plumbing and PVC work, there's an essential toolkit you shouldn't overlook. Besides the fundamental PVC pipe cutter, materials like thread tape and wrap tape are crucial for ensuring a watertight seal on threaded joints to prevent leaks. Foam insulation is another must-have as it protects your pipes from freezing and reduces condensation on cold pipes. Other PVC essentials include strap wrenches for securing parts, cutting cables for those hard-to-reach-places, and clamps for stable, hassle-free installation.
