Plumbing help - bad planning on demand water heater

[inphx]

I want to complete this hookup this weekend. I hope with stuff I can buy at home depot or lowes. There is about 6" diagonal to make that 90 degree bend with 3/4" FIP connectors.

I mangled the flex copper water heater lines trying to make it work, and then i bought a pair of the longer stainless steel sleved flex but it cant make the loop and connect.

Any ideas?

Your local Depot should stock the corrugated stainless supply lines. They are easier to work with then the copper. Get a rough estimate on length with a tape and get whats close. Slightly longer with a bend isnt an issue to get it right. If you dont want to go that route use pex and some female adapters. Youll have to buy the crimping tool. 45$ish for the stainless style clamp crimp tool.

I would go to the industrial hose supply place and have them make me one to fit. Of course they may not be open on Saturday. But they can swage the ends on the hose while you wait. And they probably have weird angle fitting/connectors that would help.

I would definitely use pex, cut it to the right lengths and make it look nice. If you don't want to buy the crimp tool you can use shark bite fittings, however in the end you'll probably spend less to just buy the crimp tool and do it right. They do have their purpose, but I'm not a big fan of shark bite fittings.....

Two short lengths of Pex and a brass 90 degree fitting. Buy the tool and a cutter, and you’ll be done in fifteen minutes if you have never done pex before.

Take your current hose and make a 360 degree loop, then connect it.

This.

Don't think he could make that tight of loop.

If possible you could raise the heater higher up the wall.

That's a good idea.

Raise it a little higher, no need to think this through and you won't need to buy anything extra. Maybe move slightly to the right also

Change the copper fitting you're trying to connect to with an elbow facing to the right (in the picture). The SS flex will do a 180*.

If you go with PEX, keep in mind it has to be a minimum of 18" from the water heater connection.

Depends on the code your under.

MI residential installs let us do it right off the tank or tankless output.

Pex is designed for 200 degrees, and to pass any residential inspection your heater has to be set to no higher than 120 degrees

It's Sunday night, what was the fix???

They can't. No local code can supersede National code.

"UPC Code 604.11.2 Water Heater Connections. PEX tubing shall not be installed within the first eighteen (18) inches (457 mm) of piping connected to a water heater."

There is no code that calls for a max of 120° F, either.

2 3/4" female adapters and one elbow. Or one coupling and one elbow and a female adapter.

It is worthwhile to make quality repairs of washing machine water connections. Ask me how I know!. I have had hoses supplied by the factory with the machine fail. I replaced them with stainless steel braided flexible hoses. I think just judging by the op's pics that the braided hoses would flex enough to easily fit in place. If I am wrong, refer to post 17.

Here in WNC they let you run pex right up to the water heater.

That is completely incorrect. There are many municipalities that have codes on the books that are not part of National codes. It is up to state and local on what and what they do not want to enforce.

Take the too long hose to Lowes and get one half the length

shorten the piece of copper bringing the male adapter closer to the wall and making the bend easy.

I would assume that the OP is building a garage which would most likely fall under IRC.

Any state, or municipality, can accept or refuse any code of the IRC. The one thing they can't do is make a code less stringent/weaker than it's written command. Which is to say, they can make it stronger/more stringent.

UPC and IBC usually fall under commercial/institutional/industrial buildings.

AFAIK, none of them can be less stringent than the national code. I could be wrong. I have been before. If I am, no biggie to me. I just learn something new.

Tommy

it can be either more stringent or less stringent than the code they adopt, they amend as they see fit per state when it comes to the IRC/IBC codes.
