Preparation Before Installation
Before you begin the installation, gather all necessary tools and verify that your shower base and piping are compatible with the Oatey No Calk drain. Proper preparation ensures a smooth installation process and helps avoid complications later on.
Tools and Materials You May Need
- Oatey No Calk shower drain assembly
- Preformed shower base or pan
- Measuring tape
- Rubber mallet or hammer
- Pipe wrench or channel locks
- Lubricant (like dish soap or silicone-free gel)
- PVC or ABS pipe glue (if using a glued pipe connection)
Inspecting the Shower Base and Drain Pipe
Ensure that the hole in your shower base is clean and free of debris. Measure the distance from the drainpipe to the subfloor to verify the pipe is at the correct height for connection. You should also confirm that the pipe is centered in the drain hole of the shower base.
Step-by-Step Installation of Oatey No Calk Shower Drain
The installation of the Oatey No Calk shower drain involves fitting the drain body into the shower base and creating a tight seal using a compression gasket and locking ring. Follow these steps carefully to ensure a proper and leak-free installation.
Step 1: Insert the Drain Body
Begin by inserting the drain body from the top of the shower base into the drain opening. The top flange of the drain should sit flush against the surface of the base. Make sure the rubber sealing washer and paper friction washer are placed between the bottom of the base and the underside of the flange to create a strong seal.
Step 2: Secure the Drain to the Shower Base
From underneath the shower base, slide the rubber sealing washer onto the drain body, followed by the paper friction washer. Then, screw the locking nut onto the drain body. Tighten the locking nut using your hands, and then use a wrench or channel locks to give it a firm turn just enough to ensure it’s snug and doesn’t shift. Be cautious not to overtighten, which may damage the shower base or strip the threads.
Step 3: Lubricate the Compression Gasket
Apply a small amount of lubricant to the compression gasket. This will help it slide into place more easily and create a better seal. Avoid using any petroleum-based products, as these can degrade the rubber over time. A simple dish soap or water-based lubricant works well.
Step 4: Insert the Compression Gasket
With the shower base set in position and the drain aligned over the pipe, insert the rubber compression gasket into the gap between the inside of the drain body and the drainpipe. Push it down gently but firmly until it’s seated evenly around the pipe. Use a flat tool or the handle of a wrench to press it in further if necessary.
Step 5: Tighten the Locking Ring
Once the compression gasket is in place, insert the locking ring on top of it. Use a screwdriver or similar tool to rotate the ring clockwise, which compresses the gasket and forms a tight seal around the pipe. Continue tightening until the ring is fully secured and the drainpipe is locked in place.
Step 6: Test for Leaks
Before finishing your shower installation, test the drain for leaks. Run water into the shower pan and check underneath for any signs of water escaping around the drain area. If any leaks are detected, disassemble the drain and inspect the gasket and fittings before reassembling.
Additional Tips for Success
Although the Oatey No Calk shower drain is designed to be user-friendly, there are some additional tips that can help ensure a smoother and more efficient installation process.
Use a Level Base
Ensure the shower pan is set on a level, properly supported base. If the base shifts or is uneven, it can affect the alignment of the drain and cause future leaks or movement in the plumbing connections.
Don’t Skip the Lubrication
Skipping lubricant when installing the gasket can lead to an improper seal and make it harder to insert the gasket. Always use a safe, non-petroleum lubricant to ease the installation process and ensure a watertight fit.
Check Local Plumbing Codes
Before starting any plumbing work, consult your local building codes to ensure that the installation meets all relevant standards and requirements. In some areas, plumbing work must be inspected or performed by a licensed contractor.
Maintenance and Long-Term Care
Once installed, the Oatey No Calk shower drain requires little maintenance. However, regular inspection and cleaning help prolong its life and ensure it continues functioning correctly.
Cleaning the Drain
- Remove the drain cover periodically to clear hair and debris
- Flush with hot water to prevent buildup
- Use mild, non-corrosive cleaners to avoid damaging the gasket or pipe
Inspect the Seal
If you notice any signs of water damage around the shower base or smell mildew, inspect the drain assembly for leaks. Although rare, the gasket may wear over time and may need replacement.
The Oatey No Calk shower drain is a reliable, easy-to-install solution for securing a watertight seal in your shower system. Its no-caulking design not only simplifies the installation process but also reduces the risk of improper sealing that can lead to leaks and damage. By following the step-by-step instructions and taking the time to properly prepare your workspace, you can install the drain with confidence and enjoy peace of mind knowing your shower drain is built to last. Proper installation and occasional maintenance will ensure this system performs efficiently for years to come.
