I am 12 years old and I try to tackle the easiest to hardest plumbing jobs. I started plumbing at the age of 9. I needed some help when I was 9. Ages 10-11-12 I was very confident and did plumbing by my self. My parents would pay me 20-40 dollars when I fixed A leak or installed A new part or did a rebuild on a toilet. I instilled a ice maker kit for my/our new refrigerator and one the first try It did not leak or ever leaked since I installed it. My parents gave me 20 dollars in cash.
