Pex lines burst on the ground in cold temp? First time I heard that.
The video doesn't take into account that (at least here in CA) even new single family homes require a fire sprinkler system. The fire sprinkler designer will size the incoming water service size, and it will probably be larger.
I thought pex was more freeze friendly than copper? Please explain
PEX doesn't degrade like copper, higher PSI rating freezing pipes will still burst, but PEX will be able to handle more freezing water than copper. PEX Tubing is much more resistant to freeze-breakage than copper or rigid plastic pipe.
never seen a house here in texas with 1", 1 1/4 or 1 1/2 inch water line. all the homes i have seen are 1/2 inch. the water meter its self is 3/4 but the city drops it down to 1/2 into the house
I'm not a plumber but I though 3/4 mains with 1/2 branches was kind of normal I was researching this for a small home build.
Same here, in Oklahoma.
3/4 TO 1/2
I have a house and a mobile home on one water meter. The house is uphill from the MH and water has to go up hill about 12 feet above the MH level , counting the basement level and into the upper floor. It is a 1" old style black line to everything. When they're using the washer or shower in the MH the water here in the house cuts down to a trickle. I have a juncture box where the line from the meter goes to a T that then goes to each home. (I put a box there several years ago when I had trouble in the T area. I am replacing the line towards the house from the T connection and I want to use PEX. I have all the regular pex stuff, but I don't have any of the new style that you stretch the end of the tube before installing. I will get all the stuff for using Umbonal pex if you think it's best. Wud I get more pressure by installing a larger line on my end of the T, or do I have to dig up the whole thing to get more pressure? I have actually cut the pressure down going into the MH, to get just the correct amount of water there.
Sorry, I didn't realize my daughter was logged in on this box. I'm Clayton cj109@triad.rr.com. I'm 78 and only want to do it once.
Damn now I wish I would have went to school to be a plumber. Instead I went to school to be an electrician but thank you so much for the video that does really help and I am replacing my entire supply line to my house my house was built in 1940.so yeah I live in freezing temperature which is in Idaho and I'm going for feet down which is required and I'm using a backhoe to dig it up and I am going to go with galvanized steel just because I don't want to deal with this problem later on or when I die and have to give this house over to my son I don't want him to ever have to deal with it I wanted to know he got a good deal and didn't have to redig this sucker up and fix it all
We're very glad we could help you with your project! A well installed water supply line can last many decades, I'm sure it won't give anyone any problems for a long time to come :)
PEX is noticably more resistant to freeze bursting than copper or CPVC. Not sure where that last statement came from.
history learn plumbing

Feel better? Good.
#1) PEX is MORE freeze resistant than copper or other metal and rigid pipe materials. You SHOULD consider PEX if installing in colder climates.
#2) Outdoor water lines should be buried BELOW the frost line. For example, IPC requires them to be 6” below the frost line and at least 12” below the surface. If you follow your local codes you should not have an issue with pipes bursting below ground (Copper, PEX, or other materials).
#3) dknowles60 is an arrogant troll and an imbecile - a bad combination.
ok so 1" line can provide 9 Gpm but at what PSI ?
Well darn. My home I am fixing up had 3/4 supply line that burst this past winter so I went with 3/4 pex to replace it. Hope I will not have issues when I move in later this year :(
My first time using pex. I am not a plumber either. I just like to do what can, when I can.
depends if its pex a or b, if pex A you shouldn't have too much of an issue. pex b you may.
Bury it deeper.
@@carlosbolanos1070 that's what she said
I am replacing the old wholehouse filter and the copper piping due some build up and rust. It was 3/4” but I am using 1” Pex b, I noticed that using the crimped type the ID goes down to 3/4 in these connectors

I’m running 153’ pex from meter to a hydrant for a 32’ fifth wheel camper and a 30’ toy hauler.
What size pex do you recommend? If you have another pipe you recommend, please advise.
Thank you
Hello there, I am building a house out in eastern Kentucky. Our house will be about 1800' from the city water hookup. There will be an elevation gain of approximately 100-150'. The house is only a 2br, 1bath, with an outside shower and outside hose hookup. We have been told that a 2" line would be best, but I wasn't sure if that seemed correct. Would a 1" be sufficient pressure for that much distance? Also, would a 1" meter work with that 2" line, or would we need to get a 2" meter? Thank you for any and all help!
I'm in Powell County, KY myself. Our local water company has 5/8" lines and the meters output to 3/4". They told me I needed to provide whatever adapter needed to get to the size pipe I use.

2 families or a family of two?
Two families
@@jayyv5059 What does that even mean...?
@@ChrisDembinsky a duplex.
I need increase the pressure would 3/4” trunk line 5 foot long then branch off to 1/2” be the right choice
pressure and flow are two different things....
I have a 2900 ft driveway. One plumber says 1in pex supply line is fine from the meter. Another says 2 in Pex. What’s your opinion.
Yeah I gotta run 660 feet. I'm wondering the same
I’ve gotta run 660ft to my 1st house then 600ft to the 2nd house. I think I’m gonna go 2” from the main then T off to a 1” to the 1st house.
go with the bigger line.....pressure and flow are two different things and you can always reduce the pressure right after the meter but you will want the better flow of the bigger line..
this was useless. how do you calculate for faucets, toilets and washers. and the distance to the furthest run.
How about outing 4 inch so my neighbor can use it
She said 10" To 12" is better
Ok that’s funny🤣🤣🤣
buy why are plumbers installing half inch pipes in my bathroom?
those are just branch lines...most likely coming off a 3/4 line feeding kitchen and bath ..
czcams.com/video/7HEdcnfY78c/video.html - this earlier video from Apr 27, 2016 discusses copper and has the same stats (eerily similar wording). I'm trying to decide on what size and copper vs. PEX.
