Summary

To connect galvanized pipes and fittings, start by measuring and cutting the pipes, then apply thread sealant. Use a pipe wrench to tighten the fittings securely. Always check for leaks after installation.

Materials Required

• Galvanized pipes
• Malleable iron pipe fittings
• Pipe wrench
• Thread sealant tape
• Pipe cutter

Step 1: Measure and Cut the Pipes

Begin by measuring the lengths needed for your project. Use a pipe cutter to ensure clean cuts at a right angle. Accurate measurements prevent unnecessary leaks and ensure a good fit.

Step 2: Clean the Threads

Use a wire brush to clean the threads on both the pipe and the fittings. This step removes debris and old thread sealant, ensuring a tight connection that won't leak.

Step 3: Apply Thread Sealant

Wrap thread sealant tape around the male threads of the pipe, ensuring full coverage but avoid excessive tape that can interfere with fitting. This helps create a leak-proof seal.

Step 4: Connect the Fittings

Thread the malleable iron pipe fittings onto the cleaned and sealed male threads of the galvanized pipes. Hand-tighten initially to avoid cross-threading, then use a pipe wrench for a secure connection.

Step 5: Tighten Securely

Using a pipe wrench, tighten the fittings firmly but not excessively. Over-tightening can damage the fittings or pipes, so it’s essential to find a balance that ensures durability without causing harm.

Step 6: Check for Leaks

Once the fittings are in place, turn on the water supply and inspect for leaks. If you notice any dripping, re-tighten the connections or reapply sealant as necessary.
