The SharkBite Water Heater Connectors are used in residential and commercial applications to connect the hot and cold supply lines to the water heater and add the option to shut off water supply at your convenience. The connectors are EPDM knitted with braided stainless steel and are available in 18” lengths. The SharkBite connection allows the installer to connect to copper, PEX and CPVC tubing eliminating the need for an additional transition fitting.

Rated 5 out of 5 by from Novice with plumbing but these fittings make it easy! I just spent a little more than i wanted to on all of the fittings, hoses and additional copper that I needed to reroute my in wall piping so I could move my water heater and laundry to the garage. I couldn't have done it without SharkBite. I actually planned for all of the pieces I needed for the job so I didn't have to wait around for a disconnect piece. It's crazy what proper planning can do for a job. Anyway, the money I saved by doing everything myself (plumber quoted me way to much for the job), I upgraded to the hybrid heatpump water heater and still came in under the quote. Definately not so intimidated by plumbing jobs anymore thanks to sharkbite.

Rated 1 out of 5 by from Shark Bite,18"x1/2x3/4 and15"x3/4x3/4 hot water co Your shark bite hot water connecters caused me to have black pieces of plastic in my bathtub after running hot water. I'm so upset about this since this has happened twice, once 6 months ago and again this week. It has cost over 200.00 dollars in plumbers fees because of your defective products. Plus the cost of your connections. The plumber had to connect all the pipes with copper fittings. Hopefully, this will end the nightmare with your products

Rated 5 out of 5 by from Easy to install and worth the price...no need to have disconnect tool unless you want to move the part I have used Sharkbites (including the ball valve) all over my property with no issues. One reviewer was upset because they thought they needed the disconnect tool to install Sharkbites. Not so. You only need it if you want to remove a part you already have installed. The only issue I have had is trying to install a fitting over pipe that has held frozen water. The water permanently expanded the pipe so the Sharkbite would not slide over it easily. Would have had this problem with any copper fitting as well. My solution was to sand down the pipe to reduce its diameter. Love this product! Bye-bye expensive plumber!

Rated 5 out of 5 by from Easy! Quick to do! hooked right up to our new Bradford White water heater and slipped on to the 3/4" cleanly cut copper pipes on the hot and cold sides. It's been over a year since I did this with no problems yet.

Rated 4 out of 5 by from Connected Hot Water Heater After getting some outlandish quotes for installation of a new hot water heater, we decided to do it ourselves. After shopping around, we found these Sharkbite connectors (with ball valves). I ordered them online, because none of the local stores have them. Shipping was a bit expensive, but we needed hot water and were willing to pay for it. After disconnecting, cutting, and draining the old pipes, the new connectors went on without a hitch. We left a few inches of copper from the old pipes for the new connectors to grab. Have had no leaks or issues in a month or more. Will be interested to see how these hold-up long term. The valves are hard to turn, and may need to unscrewed to shut-off.

Rated 5 out of 5 by from Does what it says it'll do There's no confusion, no extra, no messin' around with the shark bite with ball valve. Screw the threaded end to the threaded pipe and slide the other end onto the unthreaded pipe. You can't do it wrong. It's designed for the job and its purpose is obvious at each end.

Rated 5 out of 5 by from Made an intimidating project almost too easy. Cut, clean/deburr, slip on. It really is that easy.... Made an intimidating project almost too easy. Cut, clean/deburr, slip on. It really is that easy. Some may consider the price to be very high, but It made the job quick, easy, and leak free in just a few minutes instead of fitting and sweating copper for 15+ minutes, and worrying if it will be and remain leak free. Used two of these to install a water heater booster and prep the plumbing for an install to replace a water heater which is probably on borrowed time (its 20 years old now, and hadn't been maintained very well by the previous owner).

Rated 1 out of 5 by from Hot Water Heater Install I purchased this item after it was recommended by the plumbing associate at the store. While purchasing a replacement water heater. He told me of how great this product is and how it reduced his install times by 50%. And that this item has a 25yr. warranty.Three years later. I begin to find black flakes in my water. After doing a little research online. I've found numerous complaints of this item causing black flakes after a couple of years due to the inside of the hose deteriorating. I removed this item from my plumbing and sure enough. Black flakes were coming from the inside of this item. Do not use this item for a permanent installation. Do it correctly with CPVC for half the cost. You will have to wait a few hours for the adhesive to cure. But it is way better than having to redo the work later.

I have a small leak at the connection point at the cold water shut off on my water heater, I purchased 3/4"-18" shark bite fitting for the repair, how the connection will fit there is going to be a small kink in the line so I'm concerned if it will work?

Asked by: Zache
Hello, We do not recommend using this flexible connector if there is going to be any kinks in the hose. You may want to consider using our water heater fittings with pipe/tubing. Please see the link below. http://www.sharkbite.com/product/water-heater-installation-kits/ Thank you

I was told by a plumbing salesman that these cannot be used within 18" of a gas water heater, but could not find this in a plumbing code. Any truth to this?

Asked by: MikeC
IRC and UPC codes require at least 18" clearance from top of water heater to PEX connection. This product takes care of that. Plumber was most likely thinking of that.

Does the flexible sharkbite with ball valve take the place of a dielectric union?

Asked by: tdb2442
Good morning, Because our gaskets on the threaded side sits on top of the water heater, you won't have any corrosion at that connection point. Our SharkBite products can only go on Copper, PEX or CPVC. As long as our SharkBite connection go no these pipes, you won't have any corrosion either.

You can find all insertion depths by going to our FAQs (link: http://www.sharkbite.com/resources/faqs/fittings/) or seeing below: 1/4″ Pipe Insertion Depth = 13/16″ 3/8″ Pipe Insertion Depth = 15/16″ 1/2″ Pipe Insertion Depth = 15/16″ 5/8″ Pipe Insertion Depth = 1-1/8″ 3/4″ Pipe Insertion Depth = 1-1/8″ 1″ Pipe Insertion Depth = 1-5/16″

In what case would you choose the corrugated or braided in a water heater installation application other than the hard water issue.

Asked by: Branco
Good morning, If you do not live in hard water areas, the choice would be preference. They both handle the same temperature and pressure.
