How to stop freezing pipes

[Brett Staples]

Hello all, 

So In my rental property I just bought the old owner had the cold pipe put up against the outside wall and it keeps freezing when it snows. It is insulated in the foam case and fiber glass against the wall anything else I can do? 

Second issue. 

The drainage pipe goes through the bulk head (concrete encased staircase with 2 metal doors to the outside). Also freezes and prevents drainage. I tried wrapping in fiber glass insulation and wood boxing it in yesterday so hopefully that fixes that. I'm trying to stay away from plug in pipe wraps as I don't trust that a tenant will maintain them and don't want burster pipes.

Any and all suggestions minus moving pipes would be greatly appreciated. In order to move the pipes I'd have to gut the kitchen and move sink to other side.

@Brett Staples use pipe heating cable. It is commonly used on mobile homes for pipes that are exposed to sub-zero temperatures. It is a heating cable that is 6 feet to 30 feet long generally. It is a long heating element that gets wrapped around the pipe. It has a sensor that turns it on when the temperature gets cold to prevent freezing. You do need access to a 120 volt outlet. Problem solved for under 20 bucks. I have used it on drain pipes and water lines. You can get it at Lowes, Home Depot or Amazon.
