The plastic water pipe running to my house had already been repaired twice and started leaking again! GRRRR! Asked my certified Mr. Rooter buddy to help jack-hammer my walkway and saved several hundred dollars cha-ching. Replaced the whole line, 5 year warranty too but PEX pipe lasts forever.... Trench 18-24" deep <6hours, I will be sore tomorrow. Now I just need to ask my concrete/cement neighbor.........tired, Good night.
