I've got 3/8" PEX (1/2" O.D.) coming from my wall ...

Is this feeding the faucet or just an extra pex line?

I'm trying to install me new Whirlpool dishwasher.

usually... you add a TEE to the HOT water line
Sharkbites are allowed.

Once out of the tee... use whatever is needed to mate with the DW

 

I had an existing dishwasher, but it was 13 years old and broke. This is a dedicated PEX line to the dishwasher. The entire house is plumbed with PEX with individual valves to each service.

The faucet has its own PEX hot and cold lines. No tees.

 

Attached is a picture of what my line looked like.

Ayuh,..... That Was a 3/8" compression fittin', with a crush sleeve,....
Probably still the Best way to get where ya wanta be,....

You'd go with a 3/8" compression to 1/2" male pipe fittin',....
To a Hose adapter that's threaded 1/2" pipe,..... many are threaded 1/2" Id/ 3/4" Od,...

You can probably find both fittin's in a boxstore,...
I know ya can in a quality hardware store,....

 

no way to go from your sized PEX to 3/4 hose thread without transitions...
they make a 3/8 push fit that transitions to 3/8 MNPT.
A DW hookup kit with braided hose will connect to the 3/8 MNPT
& also come with an angled adapter for 3/4 hose X 3/8 MNPT adapter...

Peace

I had a similar scenario trying to simplify a connection to laundry tub faucets. Initially I wanted to run PEX right to the faucet adapters and eliminate the need for intermediate flexible hose step. However, I read somewhere the importance of the hosing - vibrations from the appliance will not affect the rigid plumbing if you have a hose between the appliance and the rigid plumbing. Furthermore, if you want to pull the appliance out a few inches to inspect behind it, or if you accidentally kick it or nudge it somehow, you're not going to damage the rigid plumbing. It's less of an issue with PEX, but definitely an issue with copper. So it's worth reconsidering the hose option (plus there's way more options for 3/8" hose to faucet connections - it's harder to find 3/8" PEX fittings).

 

Was this ever solved? I'm having the exact same problem. Mine looked exactly like his picture before i cut it off for a sharkbite fitting that does not fit the 3/8 pex

 

I don't know what the solution was, but it seems this fitting would do the job. If you're connecting 3/8" OD, then this one, or for 3/8" PEX, this one.

 

thanks. i ordered the flair it... on 7 days for store pick up. we will see.....

 

PEX sucks ass. I can NOT connect my new dishwasher after the last one broke and I refuse to pay for a plumber. Does anyone on here actually have advice on how to connect PEX plumbing to a dishwasher without having to spend hundreds of dollars on the tools or a plumber? I miss my old house right now.

 

What do you have now on the end of your pex line? Picture?

 

It's just the cut pvc pipe hose as it was shark crimped to to old dishwasher. Shouldn't need a picture for a cut pvc hose.

 

So is it PVC or pex? Do you have a shut off valve for it, Normally those are 3/8 , they make a hose for 3/8 to the dishwasher fitting you are using.

 

Sorry, I miss spoke. It is pex. It does have a valve, but that valve isn't threaded. So looks like I have to do pex again. I'm not willing to drop hundreds of dollars on tools for 1 project and hiring someone to install a dishwasher which should be simple is out of the question.

 

use a SharkBite fitting.

 

1/2" push-to-connect X 3/8" male compression shutoff, then dishwasher supply line and connector elbow.

 

That worked. Thank you! My wife is happy now.

 

Ok, no issue happened. Dishwasher isn't draining all the way. I did replace the disposal and removed the plug. Any other thoughts?

 

Make sure the drain hose is clear and not pinched or kinked somewhere.

 

Did you have a question?

 

I have a pex pipe exactly as the picture from the original poster, with a nut somehow attached. This nut was attached to an elbow connector directly to the old dishwasher. Problem is that I didn't save that elbow. I have no idea what the sizing was on it. I would like to use the the flexible braided hose and elbow that came with the kit and somehow attach it to the pex water supply line with the crazy nut thing on it. Any ideas? Also, for the sharkbite solution do I cut the end of the pex with the nut off?

 

@Hufdaddy you are responding to a 5 year old thread. It is always best to start your own thread with new information and post pictures so we can see what you see.

 

This is a normal dishwasher fitting. Although price is way too high here but the proper dimensions
