Reduction Of Lead In Drinking Water Act

Lead In Drinking Water Act

In 2011 Congress enacted the Reduction of Lead in Drinking Water Act to amend the Safe Drinking Water Act's section regarding the use and introduction into commerce of lead pipes, plumbing fittings or fixtures, solder and flux. The Act established a prospective effective date of January 4, 2014, which provided a three year timeframe for affected parties to transition to the new requirements. All of the metal fixtures and fittings sold by H2O Distributors are compliant with this act.

Step 1 - Insert Tube

Fitting grips before it seals. Ensure tube is pushed into the tube stop.

Step 2 - Push Up to Tube Stop

Push the tube into the fitting, to the tube stop. The collet (gripper) has stainless steel teeth which hold the tube firmly in position while the O-ring provides a permanent leak-proof seal.

Step 3 - Pull To Check if Secure

Pull on the tube to check that it is secure. It is a good practice to test the system prior to leaving site and/or before use.

Step 4 - Disconnecting

To disconnect, ensure the system is depressurized before removing the tube. Push in collet squarely against face of fitting. With the collet held in this position, the tube can be removed. The fitting can then be re-used.

How To Install SharkBite Brass Push-To-Connect Fittings

SharkBite brass push-to-connect fittings create a seamless and easy transition between different types of pipe materials. No tools are required and the fittings can be even installed in wet lines. The fitting can be rotated after installation, so you can install without having to worry about how it's positioned. SharkBite fittings are also approved for behind the wall and underground installations. If the fitting is being installed for underground use, wrap with silicone self-adhesive tape before burying.

Step 1 - Identify the pipe material

To get started, identify the pipe material. SharkBite brass push-to-connect fittings are compatible with PEX, Copper, CPVC, PE-RT and HDPE pipe. SharkBite fittings come with a PEX stiffener pre-loaded into the fitting for PEX, PE-RT and HDPE. The PEX stiffener does not need to be removed for Copper or CPVC applications.

Step 2 - Cut pipe cleanly & squarely

Be sure the pipe is free of scratches or debris and cut the pipe as cleanly and squarely as possible. If you are working with copper pipe, use a deburr tool or sand paper to remove any sharp edges or burrs on the pipe. Failing to deburr the pipe properly can compromise the fitting.

Step 3 - Measure & mark the insertion depth

Use your SharkBite Deburr & Gauge Tool to measure and mark the insertion depth on your pipe.

Step 4 - Make the connection

Push the fitting to the insertion mark you just made on the pipe. Now, turn on the water and check the connection.

Removing SharkBite Fittings

Unlike other fittings, SharkBite brass push-to-connect fittings can be removed and re-used if changes are necessary. To remove the fitting, use a SharkBite Disconnect Clip or Disconnect Tongs. To use the Disconnect Clip, snap it on to the pipe and pull up to the release collar. Press the release collar using the Disconnect Clip and pull the pipe from the fitting. To use the Disconnect Tongs, slide the tongs over the fitting and the pipe. Squeeze the tongs to press the fitting’s release collar and pull the pipe from the fitting. The SharkBite Universal brass push-to-connect fitting is ready to re-use.
