After my parents have passed I have inherited a lot of good memorable items. There is a mobile home on an acre lot a little way down the road from my late parents place. I now own. I turned the water on and there are numerous leaks. I am thinking I would replace the pvc with pex. I did repair 3 leaks but it seems to be many more. What are y'alls opinion. What do you think it would costed me? BTW the mobile home is nice on the inside.
