Key Takeaways
- A slip coupling lets you insert a tee in tight spaces by sliding over 5/8 inch to 3/4 inch per side, saving 45-60 minutes versus full pipe rework.
- Dry lines and 360-degree prep (clean + flux) are non-negotiable for a leak-free solder joint.
- Pressure test at roughly 60-80 psi and observe for 5 minutes; wipe joints to spot pinhole weeping early.
- In walls, Type L copper and lead-free solder that meets NSF 61 are standard under common codes (UPC/IPC).
- Capture job details and photos, then send a branded proposal fast using Donizo Voice to Proposal and E-signature.
What It Is and When to Use It
The COPLE Liso de COBRE para Toma A Media Tubería en Lavandería edgarelectricoplomero is a straight copper slip coupling used to create space in a line so you can add a tee for a laundry supply. It has no internal stop, so it slides fully over the pipe—perfect when space is tight and you need that extra play.
- Ideal for laundry tie-ins on 1/2 inch or 3/4 inch copper mains where you’re adding a 1/2 inch branch to a washer box.
- Great in stud bays where you have less than 3 inches of maneuvering room.
- Lets you avoid cutting back to the next coupling and re-piping a long section.
Scenario: You’ve got a 3/4 inch cold line and need a 1/2 inch takeoff to a laundry box at 42-48 inches above finished floor. You cut a short section, set a 3/4 x 3/4 x 1/2 tee, and use the slip coupling to close the gap. Clean, flux, solder, done.
- Tubing cutter (1/2 inch to 1 inch capacity)
- Deburring tool or reamer
- Emery cloth or abrasive pad (120-180 grit)
- Lead-free solder and water-soluble flux
- Torch with suitable tip; heat shield and spray bottle
- Heat-resistant mat; fire extinguisher
- Measuring tape and marker

Code and Best Practice Highlights
- Type L copper is commonly required in concealed locations under UPC/IPC.
- Use lead-free solder and flux suitable for potable water, typically NSF 61 compliant.
- Maintain clearances when soldering; shield combustibles and use a heat pad.
- Support spacing: commonly up to 6 feet for 1/2 inch horizontal runs; add supports within 12 inches of fittings where practical.
- Laundry supply height: Many contractors set washer box at 42-48 inches above finished floor for ergonomic valve access; confirm local norms.
Pro move: Document site conditions and measurements with Donizo using Voice to Proposal, then send a clean, branded estimate for approval via E-signature.
Step-by-Step: Flawless Install
1. Plan the Tie-In
- Identify the main line (often 3/4 inch cold) and the branch size (commonly 1/2 inch to the washer box).
- Account for insertion depths: typical copper fittings seat about 5/8 inch to 3/4 inch per side. Mark these on the pipe with a fine marker.
- Dry-fit the tee and the COPLE Liso de COBRE para Toma A Media Tubería en Lavandería edgarelectricoplomero to confirm you can slide it at least 1 inch total.
2. Shut Down and Drain
- Shut off the nearest valve; open a lower faucet to break vacuum and drain.
- Tip: Use compressed air or CO2 to purge stubborn water in vertical runs. Just a teaspoon of water will steam and ruin your solder.
3. Cut and Deburr
- Cut a section equal to the tee’s body length plus around 3/4 inch of play for the slip coupling.
- Deburr inside and outside. A clean ream prevents turbulence and noise; it also helps solder flow.
4. Clean and Flux 360 Degrees
- Clean pipe ends and fitting cups until bright. No shine, no seal.
- Flux both the pipe and the fitting cups lightly but fully. Excess flux can cause internal corrosion over time.
5. Assemble With the Slip Coupling
- Slide the COPLE Liso de COBRE para Toma A Media Tubería en Lavandería edgarelectricoplomero fully onto one side to create space.
- Insert the tee. Then slide the slip coupling back to cover the remaining joint. Align all marks so each joint has 5/8 inch to 3/4 inch insertion.
- Ensure the branch is vertical and the tee is oriented correctly toward the washer box.
6. Solder Like a Pro
- Heat the fitting, not the solder. Move the flame around the cup for even heating.
- When the flux sizzles and the metal reaches soldering temp, feed solder opposite the flame. You want a full 360-degree draw. For 1/2 inch joints, a 1/2 inch to 3/4 inch length of solder is usually enough; for 3/4 inch joints, plan around 3/4 inch to 1 inch of solder.
- Wipe the joint while warm for a neat bead. Avoid overheating which can burn flux and cause leaks.
7. Pressure Test and Protect
- Re-pressurize slowly and check. Aim for around 60-80 psi test on domestic lines.
- Wipe joints and observe for at least 5 minutes. Any weeping? Re-drain, re-clean, re-flux, and re-solder.
- Strap the line, add nail plates where lines pass studs within 1-1/4 inches of the face. If hammer noise is common, add a mini arrestor at the washer valves.

Pro Tips, Mistakes, and Fixes
Field-Proven Tips
- Heat sinks: A wet rag on nearby joints prevents accidental melt-outs.
- Tight bays: Pre-tin the slip joint cups lightly; it helps in low-clearance soldering.
- Old piping: If the copper is pitted, cut back to sound metal. No amount of flux fixes bad copper.
Common Mistakes
- Soldering against residual water: If it spits or turns your solder into a dull blob, the pipe isn’t dry. Purge and try again.
- Over-fluxing: Excess flux inside the line can lead to green corrosion. Use a thin, even coat.
- Short play for the slip coupling: Without at least 5/8 inch of movement, you’ll fight the fit. Cut and recalc your gap.
Fast Fixes
- Pinholes or weeping bead: Reheat, add a touch more solder, and re-wipe. If it persists, disassemble, re-clean, and re-flux.
- Burned flux: Let it cool, disassemble, clean back to bright metal, re-flux, and re-solder.

FAQ
It’s a copper slip coupling used to create the space needed to insert a tee on an existing line for a laundry supply. Because it has no internal stop, it slides fully over the pipe, letting you shift alignment, set the tee, and finish with a tight, soldered connection.
Can I Use a Slip Coupling on a Wet Line?
Not with solder. Any water in the pipe will turn to steam and kill the joint. Either purge and dry the line completely or use press fittings designed for wet conditions. For the classic COPLE Liso de COBRE para Toma A Media Tubería en Lavandería edgarelectricoplomero solder install, dry is mandatory.
What Copper Type Should I Use in a Wall for Laundry?
Type L copper is commonly used in concealed potable water runs under UPC and IPC jurisdictions. Pair it with lead-free solder and compatible flux. Strap the line properly and protect with nail plates if near framing faces to avoid future fastener punctures.
How Much Insertion Depth Do I Need for a Slip Coupling?
Plan for about 5/8 inch to 3/4 inch insertion per side on common residential sizes. Mark your pipe so you visually confirm full engagement before heating. The COPLE Liso de COBRE para Toma A Media Tubería en Lavandería edgarelectricoplomero relies on full-depth seating for strength and a leak-free bead.
What Pressure Test Is Appropriate After Soldering?
For domestic water, many contractors test around 60-80 psi and observe at least 5 minutes while wiping joints to spot weeping. If a jurisdiction requires a specific test (time or pressure), follow that local standard. Always document results in your job notes.
Conclusion
A clean, durable laundry tie-in is simple when you use the COPLE Liso de COBRE para Toma A Media Tubería en Lavandería edgarelectricoplomero correctly: plan your gap, dry the line, seat 5/8 inch to 3/4 inch per joint, solder 360 degrees, and test at 60-80 psi. Expect to save 45-60 minutes versus full re-pipe in tight bays while delivering a pro finish. Ready to quote this scope today?
