Worth every penny in time saved
This is the easiest and quickest way to connect a water heater!
I hope it lasts as long as the water heater. I worry about flexible connections...

Eventually produces BLACK carbon flakes
Stainless steel braided hoses that have the black rubber lining tend to break down when exposed to chlorinated water over a period of time, and this is especially evident when connected to the hot water side of the homeowners system. - City of Kerrville Water Department TX

Very Convenient, Worked Well
I had to replace the dip tube in my hot water heater. I used this product to connect the cold water pipe to the heater afterwards. Saved lots of time, money, effort because I did not have to rework the old PEX piping.

Would buy again
Used to hook up a few unit ventilators in a tight spot . wouldn't consider it a permanent fix but building is being demolished in the spring so good for one season in my opinion.
No leaks!

Yes, the flexible tubing can be bent but not kinked. The maximum bend is about 5 times the tube size, ie. 5x3/4"=3 3/4".

Asked by frank 14 years ago
Add your answer
Verified Reply- PexSupply StaffOne side of the connector is designed to connect to the 3/4" standard connection on a water heater, while the other side connects to 3/4" PEX, copper, or CPVC using a SharkBite connection.

Yes.

One end goes to the water heater connection, the other end like you stated goes over a ¾ pipe, (cvpc, pex, or copper).
Was this review helpful to you?

Yes, It just slips over the cut off end of a 3/4" copper pipe, you can't get any easier. I use these any time I put in a new hot water heater. Scott Sandquist

Whatever size Sharkbite fits in Pex will fit the same on PVC and copper

It is not totally lead free according to www.sharkbite.com but is considered safe for potable water in 47 states. They do make lead free products with an "LF" suffix on part number for sale in CA, VT amd MD.
