But HDPE, fusion butt-welded or even MJ is all you need for anything 2" and under.DD, why do you recommend insulating the supply to the house?  

Just bought a new welder the other day and will start welding up new tomato cages this winter.

Cut the wall open, saw a dent in the pipe, cut the damaged section out, replaced by  welding in the replacement.

Put a welding torch in the college educated kids hand and lets see him repair a bridge or pipe fitting, now who looks smart.  

The slightly higher cost of solvent-welded Schedule 40 PVC or ABS will pay for itself over time in reduced service calls.3.

@Tal Shachar also not sure if Menards is in your area or not but in addition to off the shelf Jen Weld windows which I've used many times https://www.menards.com/main/d...   

I had an increase in welding income but more than a 20% decrease in real estate income.

Since then, I've attained a welding Journeyman Certificate, started an incorporated company, upgarded my schooling, completed my Mechanical Tech Diploma and pursued a Project Management Certificate.

@Lucas MillerIn my 20's I went to real estate school and became a licensed agent...I did this during evenings after my welding job!

If you can tie your shoes in the dark, you can mig weld.
