I live in a house built in the 1950's . Pier & beam construction , so I can get under the house to work . Just barely . I am getting too old & fat & stove up . :-(
Last year , I re-piped the hot water ( did not replace the stub ups going up into the walls ) . Had a water leak , some where where the hot water piping was buried in the dirt , under the house .
Leak returned & I have re-piped almost all of the cold water , that was in the dirt , under the house . Did not fix the leak .
The main water line , from the water meter to the house was 3/4" copper . I rented a mini-excavator at Home Depot & dug a ditch for the new water main .
I went back with 1" white PEX . Under the house , I used a 1" PEX to 3/4" male pipe thread fitting to transition to the 3/4" copper cold water lines . I tried to use a 1" water meter fitting , at the water meter , but had to use the old 3/4" water meter fitting and transition to the 1" PEX fitting .
The main bath and bath in the back bedroom had 3/4" copper going to it , for cold water , as did the water heater . The kitchen had a 1/2" cold water line going to it . That stayed the same size .
The shower , lavatory and toilet reduced down to 1/2" , in each bathroom .
All have plenty of pressure , so 1/2" seems to be fine / sufficient .
I used the PEX brass barb fittings ( two ) that use the black copper crimp ring . I had to purchase the $ 109 crimp tool that would go up to 1" . It has dies to go down to 3/8" , I think .
The PEX & ditch were done between Christmas Eve and New Years . I checked the water meter yesterday and all the dials were stationary , indicating no leaks .
Praise the Lord !
I bought the PEX , crimp tool & fittings at Home Depot & Lowes . The 1" white PEX id very stiff , on a cool / cold winter day ( 40's or 50's ) . It has a very determined memory from being packaged in a coil . I had to walk it down into the ditch & use a hoe to drag dirt down on top of it . To weight it down and get it to stay in the ditch .
It was very stiff , bending it to match up with the 2 brass barbed crimp fittings . But , so far , all is well .
I do not know about smaller sizes of PEX . They are probably less stiff . Also , I read there are 3 different types of PEX , A , B and C . I think the PEX I bought is probably A ? B & C are suppose to be less stiff , than A , I think ?
God bless
