Looks like that is the only solution. I was thinking that someone might have tried one of the other solutions but, I guess not.

I am looking to for the best design for recirc. I am up for ripping out all the hot water lines or something in between. I came up with three ideas. But, I was looking for someone that has done it and what worked for them. "Why would you want instant hot water at your washing machine?" Wife...

I have sealed up all my crawl space vents. I am installing an outdoor tankless on the side of the house. I would rather not put a hole in the floor joint that is sitting on the block that holds up the house. There are a couple of closed crawl space vents that I would rather use to run the...

It is really necessary to tie down PEX every 4 feet? I am replacing PolyB with PEX. The previous plumber tied down Poly B all over the place. I had to make a lot of holes just to cut the tie downs. Most of other run goes through floor joists (working on the plumbing on the second floor of a...

Instead of putting tar on the foundation. I looked up the residental code. It calls for a pipe in the f0undation twice the size of the water line. . I put in a 2" schedule 40 PVC pipe in the foundation. The old pipe was just laid under the sewer pipe (PVC) in drainage rock which would not...

Another question about the project. The water line was a challenge to find. It was not a straight shot from curb to the house. But, it is done and the new pipe will be using the same path as the old pipe. Now that I am ready to lay the 1" pex in the trench, is it worth it to put in a tracer...

Thanks Jeff!!! I think I will go with sand. I am going to snake the tubing for expansion.

I am going to bury 1" in PEX in clay soil in North Carolina. - Can I bury the PEX directly in the clay as long as the clay is firm and just put the clay soil back on top? Or do I need a bed of sand. - I was thinking about wrapping the pipe in polyethylene foam tubing and snaking for expansion...

Thanks for the doc. I am going to read in depth. But, the first thing that stands out, is the issue with burying it. I dug most of it with a hand shovel. But, I used a power washer to get to the old pipe and put the new pipe deeper. So, the new pipe is sitting mud in some sections. Do I...

Also, I putting in a new main line with PEX-b 1". It is about 30" in the ground same as the old one. Should I snake it a litte back and forth in the tench to give room to expand and contract? It is only 50 ft. In North Carolina, the frost line is only 9" so, code is 12". I do not think...

The current setup is city shutoff>>>>>> house gate valve >>>>>> PRV. I want to do the samething city>>>house>>>PRV but, I was going to put the shutoff and PRV in the same box. The PRV has a nice gauge on it and it would be nice to see water pressure. But, I doubt I would ever have to...

Can I located the shutoff behind an access panel? I am replumbing the house. Current setup is the water shut off is in the back of the closet and is a red wheel handle. I would like to remove it and install a ball valve shut off with a pressure reducing valve in a box with an access door...

It is 1" inch Pex-b. It had a little scoring coming out of the concrete foundation. I pulled a 3/4" pex jig I made. It pulled it through 3 feet of mud and clay. But, 5 feet was too much and the 3/4" snapped. I wanted the new follow the line of the old pipe. They put the old pipe about 30"...

Thank you. I have closed the vents and put in a vapor barrier.

I have some old black plastic main line about 36"deep in the ground. I was able to loosen in up with a power washer without having to dig much. I was able to use my own strength to pull most of it. But, it got harder and I used my truck. Now I would like to put in 1" PEX-B by hooking the old...

Ok cool. Thanks for the advise. Doing a poly B to pex for the whole house and want to do it right. :)

I am in installing Pex-b in the house. I have lights in the crawl space, to work on vapor barrier, duct work and etc.... Do I need to cover pex with a UV protector? The Pex I have says that it has 6 months of UV protection. Does that mean 6 months of direct sunlight over the course of the...

Thanks folks!!!! They went with Poly B (the grey stuff ) a few feet from the house. So, I did not see the black stuff until I was into digging. It might have be worth saving but, PEX is so cheap ($70) for a 100 ft. And I had invested the time and effort digging. I did not want connections...

I am replacing p0ly B with PEX. Starting to replace my line between the meter and the house first. I found out that the main line is 3/4" ish almost 1". It is old black plastic pipe. It uses barb fittings. There is a hugh difference in diameter from the old 3/4" to the new PEX 3/4"...
