ways to bring pex into detatched garage

[nerraw117]

Going to be trenching pex from my crawlspace of my house to my garage. Having a hard time coming up with a plan to bring the pex into the garage. I was thinking just using a electrical lb connector in the side of the lower part of the garage. Am I missing a obvious better way? thanks

You'll need a HUGE LB to make the bend in, unless you use a 90. I guess it's sufficient to protect the PEX from UV, but it's not so good at protecting it from freezing. The usual way is to bring it up from underground.

I ran 3/4 PEX with 90 in exactly that - electrical conduit. Designed to hide "water" from the tax man and protect pex from UV. You may want to consider insulation though in NC...

I figured the ideal way is from the bottom but didnt know what problems I was going to run into dealing with the block wall. Im assuming drilling down through the studs where it meets the concrete but dont know how I was going to intersect it through the block wall

 

[dcg9381]

The advantage to doing it that way is that you'll have some freeze protection. You could drill all the way through and intersect it by digging a bit under the foundation. I don't like drilling foundations myself - esp not that close to the perimeter, but maybe I'm paranoid.. (or just lazy)

If you intersect it with another drill line horizontal, you'll never be able to get it in there. PEX doesn't do 90 degree turn and no way to secure a fitting.

do you have a pic of your setup by any chance? Im thinking if its a problem I could come up with a way to drain the system. Im just using it for water to fridge, wall mounted pressure washer and small hot water heater for dog washing

I came in under the back block wall and foundation. I then cut the floor to trench it into the bathroom. Its all connected to a frost free hydrant.

I concreted the floor back over and now its under the new floor I poured over that.

Water in to hydrant, then out to 1/2 CPVC. down under the floor (crawlspace) to feed sink, toilet and stubs for future shower. I added the tee with the hose line when I remodeled the utility room in the house. The washer/dryer lived in my garage for a few months.

Im assuming my block wall is filled with concrete and my framing is mounted on top of that. I dont know how I would be able to drill all the way down.

Could you use an adapter fitting to convert the pex to iron pipe. Do the conversion in your ditch, bring the iron up the outside wall and then drill though the wall.

Even though it's built on a hill, I doubt that all those block are filled.

It may be a matter of cutting the concrete, bringing in a post hole digger to get down through the base material.

What's the frost depth down there in NC ?


Are you putting in a sink ? how are you going to get rid of the water ?

I wasnt going to put in a sink because I was thinking it would be hard to handle the drain situation. I could always kill 2 birds with 1 stone I guess

So do you have a floor drain ? You have water coming in (not sure what you are using it for) but how are you getting it out ? Where will it drain to ?


You could always just put a frost-free hydrant outside the door and not run it inside.

I do not have a floor drain. I was wanting to hook water to my fridge, a wall mounted pressure washer and a small hot water heater to give the dog a bath. A sink wasn't very high on the list so I don't have to have a drain. I have a faucet a few feet away attached to the house I use to wash my hands.
