I am not a plumber . But I have been in construction for over 35 years . And have learned as much as I can from the other trades .
I am capable of doing plumbing in a workable / safe manner . I do not wish to cause myself problems .
Years down the road no one is going to know or care what work I self performed . And is it does not give trouble , no one is going to care .
When I upgraded the electrical service to 200 amps , only reason I took out a permit is it worked put better to let the power company re-tie in the new service . I could not source the insulated butt crimps / splices and I did not have access to a crimping tool to do the side by side crimps .
1-1/2 years ago I replaced the water main from the meter , in the alley , to under the house . Ditch ended up costing quite a bit more than the material . Rented a mini-excavator from Home Depot . One day to cut the ditch and another 1/2 day to back fill the ditch .
Used 1" white PEX with bras fittings and the copper crimp rings .
