How to Install a New Tap with a Pipe Saddle Clamp – DIY Guide 2026

Adding an extra water access point to your home's plumbing system doesn't have to mean calling a professional or enduring complex pipework. With a tap with a pipe saddle clamp (also known as a water saddle or self-tapping valve), you can complete this DIY project in just a few minutes, only shutting off the water supply for a short time. This clever device works by clamping onto an existing water pipe and allowing you to drill a precise hole through a built-in guide. The key requirement is that you have a section of pipe—even a short one—that is fully accessible so the clamp's jaws can grip it securely. Once the hole is drilled, you simply screw in the new tap, turn the water back on, and your new water point is ready for use. Whether you're adding a connection for a refrigerator ice maker, a garden hose, or a washing machine, this method is efficient and reliable.

Materials Needed

• A "flying" water saddle clamp consisting of two U-shaped collars
• A rubber gasket
• A metal bushing and 4 screws
• A tap (optionally with a reducer)

Before starting, ensure you have all components. You can find high-quality plumbing supplies and fittings in our Home Improvement section.

Preparation and Marking

• Clean and sand the area of the pipe where you will work to ensure a good seal.
• Use a 10 mm drill bit turned backward (or a centering tool) inserted into the saddle clamp to center the rubber gasket.
• Position the back part of the saddle collar on the pipe, holding it steady with your hand.
• Keep the drill bit inserted to prevent the gasket from shifting, then align the front collar.
• Using the 4 provided screws, firmly secure both collars of the saddle clamp to the water pipe.
• To make drilling easier, score the pipe surface with a steel punch or center punch.

For a smooth workflow, having the right home improvement tools on hand makes all the difference.

Mounting the Tap

• Turn off the main water supply and drain any remaining water from the pipe.
• Using a metal drill bit on a low-speed drill, carefully drill through the water pipe.
• Thoroughly vacuum or blow out any metal shavings produced during drilling.
• Insert the provided metal bushing into the internal seat of the saddle.
• Cover the tap's threads with PTFE thread seal tape (like Tangit) to prevent leaks.
• If the new tap has a smaller threaded connection than the saddle opening, use a threaded reducer fitting (also sealed with tape).
• Screw the tap into place and tighten securely with a wrench.

Once mounted, restore water pressure and check for leaks. This simple addition can transform your utility space. Consider pairing your new tap with a stylish kitchen island or cart for an efficient workspace.

Tools Required

• Drill
• Hammer
• Vacuum cleaner or blower
• Adjustable wrench (monkey wrench)
• Screwdrivers

Frequently Asked Questions

Can I install a saddle tap on any type of pipe?

This method works best on copper, PVC, or PEX pipes. Ensure the pipe is in good condition and fully accessible. For outdoor applications, browse our Garden Supplies for compatible hoses and fittings.

Do I need to turn off the water for the whole house?

Yes, you should shut off the main water supply to avoid flooding. The process only takes a few minutes, so it's a minor inconvenience. While you're upgrading plumbing, consider adding bathroom vanities with integrated water connections for a complete renovation.

What if my pipe is not perfectly round or has corrosion?

Clean the pipe thoroughly with sandpaper first. If corrosion is severe, replace that section of pipe before installing the saddle. For outdoor setups, a shed can protect your plumbing from the elements.

Can I use this tap for a garden hose?

Absolutely! This is a common application. Just ensure the tap has a standard hose thread. Complete your outdoor setup with outdoor patio furniture for a comfortable garden space.

Is it safe to drill into a water pipe myself?

Yes, as long as you follow the instructions carefully and use the proper saddle clamp. The clamp acts as a guide and prevents over-drilling. For additional safety, equip your workshop with proper home improvement safety gear.
