Please see photo. The hoses on the drain side of my tankless water heater are bending and kinking, reducing the free flow of the drainage water. Can someone point me to the same type of hoses at THD or Lowe's so that I can replace them? Any ideas to reduce the bending beside supporting the hoses in various orientations to reduce stress (which I've already done). Do stronger hoses exist that I could use instead? Also, can you please point me to those black clamp connectors shown in the photo?
Thanks.
Thanks.
