The SharkBite Water Heater Connectors are used in residential and commercial applications to connect the hot and cold supply lines to the water heater. The connectors are EPDM knitted with braided stainless steel. The connectors are available in 12 in., 15 in., 18 in. (with and without ball valve) and 24 in. 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 Easy install, no leaks, quality product !! I used 2 11'' flex hoses and a in line ball valve on my new hot water tank install and it made what might have been a tough job very easy

Rated 1 out of 5 by from black pieces flow out of hot water my bath tab hot water comes with black rubber pieces, and after long time diagnosis, the only possible explanation is that the black rubber pieces come from the Shark bite water heater connector

Rated 5 out of 5 by from Best plumbing product I've used... Had to change out a water heater this weekend and of course, none of the water connections lined up. I didn't really have time to rebuild all the copper and sweat all those connections so I thought I would give these a try, simplest, most effective product I've used on a plumbing project... test fit, cut pipe, sanded burrs and slipped right into place. No leaks... amazing!!

Rated 1 out of 5 by from rubber liner deteriorates In 2011 I installed these braided flex connectors from sharkbite; it was an easy install no leaks I was very happy, but after 2 years my faucets strainers were being clogged with small fragments of black rubber. I finally found the water heater was loaded with the rubber and found the rubber liner in the sharkbite flex line was deteriorating. I called Sharkbite and they said they changed the liners and if I bought new lines manufactured after 2011 that they would have the new liners. That was late 2013 or early 2014 and now here it is 2016 and the lines have deteriorated again. I don't recommend these and will not be suckered into them again.

Rated 5 out of 5 by from How did I not know this kind of product existed?!?!? My biggest worry about my water heater switch out was getting it reconnect to the water line. I have a pretty handy friend that offered to help me switch it out. When we grabbed the water heater he picked up a few of these to get it reconnected to the water line. I was like WHAT!! it just pushes on the the copper piping and threads onto the water heater! I was in shock at how simple this connector made my water heater switch out! Its strong flexible and so far shows no signs of having any problems with heat from the water or the vent line on the water heater. I will continue to use these on any future water heater or water softener switches. Thanks

Rated 5 out of 5 by from You need this for the new gas water heaters. If you have a gas water heater, you are in for a surprise when you go to replace it. The new standards have changed the size enough that the old connections are not going to fit. The new designs are taller, and bigger around then the old ones. Because I don't like messing with gas lines, and because the water lines were too long anyway, I moved the hater a bit so the gas line fit. Then I cut the water lines back, and used 2 of these. Installation went easy. Because they are flexible, I didn't need to line things up. With the "Push-to-Connect" connector, I didn't need to solder anything. Talk about easy. And they are even rated as a dielectric connection.

Rated 5 out of 5 by from turned a "call a plumber" into a "I think I can" job My old water heater was a standard 48" tall unit in a 36" tall crawl space. Someone dug a hole, lined it with plastic, set two concrete blocks in it, and placed the 48" tall water heater on top of the block. I'm not a plumber and don't trust myself with a torch under a house. With these fittings, I was able to get the job done. I cut the old copper pipe off, installed these, connected to the new water heater and BINGO! It works, no leaks. Actually, one of the two I bought leaked. Not sure what the problem was. I returned to Home Depot, exchanged for a new one and it's all good.

Rated 5 out of 5 by from Easy hot-water connect & no leaks The SharkBite 1/2 in. x 15 in. stainless steel push fit x FIP flexible water heater connector is a great new way to connect a water-heater or boiler to your home system. The female threaded ends screw onto the nipples from the tank with a bit of teflon tape to prevent sticking or corrosion and the SharkBite ends push right over cleaned and prepared pipes from the hot water inlet and cold water feed. When the water was turned back on, no leaks were detected from the new stainless steel mesh connectors and not even a droplet was released by the push-on ends. The push-on ends will require a special clip (sold separately) to remove. I recommend these SharkBite connectors for both do-it-yourself and professional plumbers.

I have a leak in my PEX water line underground. After digging through the stony ground I found the the point of the leak is at a bad over a rock. Can I use the flex to connect the cut out sections of the water line undrground?

Asked by: olab
Good morning, No. Our Flex hoses are only certified in accessible locations and not for underground burial. We do not recommend using this item to make a repair on your like. Our Standard SharkBite Push-To-Connect are certified for underground use. Here is a link to our installation guide: http://www.sharkbite.com/sharkbite/wp-content/uploads/SharkBite_Installation_Instructions_2016.pdf

Do these hoses isolate the heater electrically? My current heater has 220 grounded to the junction box on the heater which is electrically grounded via the copper pipes.

Asked by: jlwing
Good morning, No. Our SharkBite products do not conduct electricity and can cause a break in the ground. You will need to create a jumper to bypass this item.

My sharkbite has disintegrated and the rubber is coming out leaking in my tub.  i need to replace it but can't remove the old shark bite, could you advise on how to remove it?

Asked by: gatorfan
Good morning, To remove a SharkBite fitting, use the disconnect clip to depress the release collar and release the pipe from the fitting. Below is a link to a youtube video that will show you how to disconnect the fitting from the pipe. http://www.sharkbite.com/how-to/sharkbite-push-fit-fittings-how-to-install-pex-tubing-copper-tubing-and-cpvc-tubing/

I've read some reviews claiming that the rubber lining will disintegrate especially on the hot water side. Has this been corrected or is it simply not true? Thanks!

Asked by: crawdad
Hot Water Installer, We will reach out to you through the e-mail you provide to get the date code on your connector. This issue should be resolved and need to confirm you have the newer version.

 I am getting rubber flakes coming from the inside of the hoses. Will it deteriorate  so bad that one day the  hose will explode from under pressure and result in water damage to my house ?

Asked by: Hot water installer
This was an issue we had about 2 years ago where a bad batch of hoses came through our warehouse. The issue has since been fixed. We'd be more than happy to replace it for you, but we would recommend it be replaced. You call in to our technical support hotline and request another one be sent to you. The number is 1-877-700-4242.

I want to make a heat trap out of a flexible water heater coupling hose, but I'm concerned about bending it too tightly.  Can you tell me the minimum required bend radius for a 3/4" steel braided hose?

Asked by: Bill B
Greetings Bill, The bend radius is going to be similar to our PEX tubing which can be found on page 11 on this link: http://www.sharkbite.com/sharkbite/wp-content/uploads/2013/06/SHARKBITE-PEX-INSTALLATION-INSTRUCTIONS.pdf.
