Flex Hose Drain Pipe Leaking

My 2005 Cardinal kitchen slide out has a leaking 1.5" PVC flex drain hose below the kitchen sink. I removed the drawers and saw the white flex hose cracked. I can't see where the end of the hose connects into the tank.

It appears I will have to cut the thin wall panel under the sink counter just to get to the cracked part of the hose. My thought is to cut the hose and put a rubber coupler in between and over the two pieces. Then seal with some plumbers GOOP and put clamps on the coupler. I was thinking if I needed more hose length I could use swimming pool or auto radiator hose.

I really don't want to tear apart the trailer any more than I have to. Does someone have some advice on how to patch the hose? Thanks.

    My research on the Rescue Tape indicated to me it is a good product to have around. Although it seems it is not intended to be necessarily permanent. Also the complaints about the tape have been when it was applied wet and under high pressure.

    I have fixed many polyethylene water lines with a piece of rubber and a hose clamp. These repairs have lasted for years, even under pressure.

    Whenever I make a plumbing repair or am concerned about the number of water lines in an area, If possible, I like to place a pan below the area in question. Then I put a cheap water alarm in the pan. This practice has saved me much time and expense.

    I also work hard to fight the desire to be a perfectionist. So if I have a problem, I try to resist the temptation to replace the whole system or vehicle. I believe we can go overboard on these repairs. But that is just me on my stuff.

    Rescue Tape....Here


    Thank you!! Last night, we discovered the new-to-us 5er has a slight crack in a gray tank line (must have been some water in there that froze?)
  • ScottG, I understand and can appreciate your position.
    h2guy, Clamping would probably be ineffective if the entire hose were clamped.
    kakampers, thanks for telling me about the Rescue Tape. I intend to purchase some.

    Thanks for the replies.
  • If its really a flex hose, won't clamping be ineffective??
  • In plumbing, it's all about doing things the right way in order to keep them working properly. Using goop, sprays or any other miracle stop leak will give you temporary results at best.
    You'd be better off replacing the assembly and making sure it doesn't kink or bind with slide movement.
