What happens here

Begin installing the new PEX water supply lines. Use 3/4-inch PEX for the main supply line to ensure optimal water flow throughout the house, and branch off to 1/2-inch PEX for individual fixtures (sinks, toilets, showers). Use a PEX crimping tool to secure connections and ensure leak-free joints. Drill appropriately sized holes in wooden joists for the PEX lines, keeping in mind PEX expansion. Properly route the PEX lines, ensuring they are not kinked and are secured with appropriate hangers or clamps. This step covers the installation for the kitchen, bathroom, and laundry areas.

Goal: Install the new PEX water supply lines, running 3/4-inch PEX for main feeds and 1/2-inch PEX for fixtures, using a crimping tool for secure connections.

finally it's all vertical [Music] vintage all right folks back for more got all my supplies to start running all new lines here so uh the only really solid way of doing it is starting from the beginning and then working our way out so I'm assuming our water heater is going to go back in the same spot here we're going to place our bracket where the lines are going to have the water shut off valve and all that fun Jazz here so what we're doing is we're getting our connectors to our water heater first so this goes to our water heater there we need water shut off valve and the first line of lines that are coming out in order to have the most amount of flow is use 3/4 inch to be our main feed and then it'll break down into half inch when it goes to the actual utilities like a sink or whatever reason why is I think when they do like the gallon flow whatever the calculation the/ inch only gets to 82 or something like that and then the 3/4 inch jumps to like 1.82 like almost doubles it so that's going to be the most efficient way of using this put this in here get this cramp plint ring on put our water stop valve and then from that point on start working our way out okay we have our hookups for our water heater we have our shut off valves Let's uh make our lives easy and work on the cold water first and then we'll do the run heating so I have my water inlet here my water heater there uh The Gray Line the pencil mark That's indicator of just cold water what needs uh the black Sharpie that's an indicator where I need hot water so we'll start with the cold run it straight run it back and then over to the [Applause] kitchen this 3/4 inch stuff is like as stiff as a rock especially when it's coiled up one line will go down there into the kitchen this line will go into the bathroom when you're drilling holes you have to account for expansion of the pecs so if you're using half in pecs you got to drill a 3/4 in hole if you're using 3/4 in pecs like we are you got to drill a 1in hole so put that in your [Music] got a little too excited didn't stick to the plan got to have a plan without that a plan you're going to be wasting all your money on supplies moving on to our first halfin pipe breakoff this is going to be cold water for the washing machine how exciting is that doesn't help when you have a million things in your pocket screws fittings Clips basically a whole hardware store one man one holes fortunately everything's close together here on this back side of the…
