Solution to Kinked Hoses on Drain Side of Tankless Water Heater?

[dclynds]

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.

The clamps look like HILLMANS; https://www.amazon.com/s?k=plastic+...ose+clamps,aps,120&ref=nb_sb_ss_ts-doa-p_1_25

And you could change or amend the hoses with PEX, which have formed bend devices.

Thanks Snoonyb. Are these the bend supports you are talking about? Is there a way to determine what diameter I need without removing one of the hoses?

Correct and just measure across the fitting on the appliance, to determine the diameter.
