SharkBite’s Braided Flexible Water Heater Connectors are great for easily connecting your hot and cold water supply lines to your water heater. Simply apply pipe thread to the MIP nipples on the water heater and then thread the female connection on the connector to the nipple and tighten with channel locks or a similar tool. These hoses are also available in Corrugated Stainless Steel and are also available with an integrated Ball Valve.

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 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 5 out of 5 by from Brilliant!!! I had one of those nightmare weekends where I had an unplanned water heater installation. I hate to sweat solder and these SharkBite connectors make water connections a breeze. The person that invented the ShartBite connectors is a genius! The braided stainless steel water heater connector is the way to go as it gives you a lot of flexibility in making the connections. I have 3/4" copper pipe and cut the pipe to the old water heater. I set the new water in place and made the water line connections using the ShartBite connectors. It was so simple. No leaks. I had hot water in no time. Thank you SharkBite and also to Home Depot for carrying their product.

Rated 4 out of 5 by from the war against water heaters ITEM:3/4 in. x 24 in. Stainless Steel Push-Fit x FIP Water Heater Connector I bought the steel web wrapped water heater connector because the water heater top is difficult to reach and has limited space to apply the wrench to tighten or loosen. Note that this hose is replacing an identical hose that began to leak in less than two years use. Even with the failure of the previous hose, I still bought another. The hose failed because the angle of the hose was too sharp. This time I put on a longer feeder hose so that there was an easy curve. Do not let this hose kink.

Rated 1 out of 5 by from These water heater connectors start shedding rubber particles shortly after installation I had been experiencing black goo and rubber particles clogging many of the screens and filters in my house. After on line research I found it could be the black rubber liner in these connectors that was deteriorating. In deed that was the cause. I removed the hoses and cut them in half and the hot water hose was filled with black gunk. Also some in the cold water but not as bad. SharkBite claims it is caused by hard water and chlorine. Since most of the US has hard water and chlorine it would seem few are safe from deterioration.

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 1 out of 5 by from I just called Sharkbite and Customer Service was as expected ... lousy I have the these lines on a water heater installed in Jan 2013. Thankfully I read these reviews, otherwise, I would never have figured out the cause of this problem. Who would expect these lines that are only 2.5 years old to start disintegrating in Delray Beach, FL. I just replaced them over the weekend and called customer service this morning. They did exactly what I anticipated which is to tell me that it is my problem to address. Evidently, they don't stand behind their overpriced and inferior products, but that should not come as a surprise in this day and age. Simple install but very poor quality!!

Rated 1 out of 5 by from Rubber failure Unfortunately the black rubber lining failed in about one year. I started noticing small black rubber particles when filling the bath tub for the kids. I looked online and sure enough the sharkbite hose are prone to failure. I checked several other faucets and they had black rubber particles practically blocking the small faucet filter. Our shower head was also clogged with black rubber particles. I like the idea, but unfortunately they just don't last and will put black rubber particles into your hot water supply.

is there a difference between the water heater connectors and the water softener connectors? i need a 3\4 to 3\4 for a water softener but you do not have that size? will the water heater connector work?

Asked by: thomas a
Good morning, Water Softener is designed to connect to a water softener device which will have a 1 inch output. If your water heater has 3/4 inch output, you can just use the standard water heater connectors.

installed 2 3/4" SS flex connectors in 2017 to my gas HW Heater. An "home inspector" said the SS flex lines were not acceptable within 16" of the flue vent because the braided SS lines are not able to withstand heat discharge from the gas flue. True?

What is the size washer for a 3/4 flex hose? I have tried a hose bib and it appears to be slightly too large. Where can I find the correct washer?

Asked by: Steve
Good afternoon, We have made adjustment to our Flexible Water Heater connectors at the beginning of 2017. We are no long able to send out Washers due to the washer no longer meeting the same dimensions and the compartment the washers sit in has changed. We apologize for the inconvenience this may cause.

There seems to be a lot of references to the breaking down of the rubber in your flex hoses. What do I need to look for should I decide to replace the defective hose?

Asked by: Ralph6410
Good morning, The places where these hoses experienced issues were in hard water areas. If you feel your home is in a location where there is hard water, we recommend replacing these hoses after 5 years of use. If your home is not in hard water areas, we recommend replacing them within 7 years of use. All rubber components will eventually break down over time. All our hoses carry a 2 year warranty. Every issues we've handled, the hoses were between 3-5 years old. We have upgraded the rubber so they make it closer to a 5 year life span. We also came out with corrugated hoses that do not have rubber liners.

is there a reason why hot water heater;s need a copper hose and braided stainless hose. my hot water heater has a copper hose for cold and stainless for hot. if i put a copper hose on the hot water would there be a problem.

Asked by: Panda
Good morning, We manufacture products per the plumbing needs. We would not be able to tell you why a plumber installed your water heater as they did. You should work with a local plumber to find out why they have your hot water heater set up as it is. We only manufacture stainless steel water heater connectors.
