Waterbox Infinia 190 return hose

[Eddie909]

I have a quick question, I just purchased an WB INFINIA 190. I want to replace the Return hose that is lD: 25mm OD: 31mm. I was thinking about using 1 inch hose. It’s not making a tight connection to the return barb fitting. Other than hard plumb what do u suggest??
Thanks
Ed

I don't remember the size but I used silicone tubing when I set up my WB 330.7

Hello, question regarding the Waterbox cabinets - I ordered a 190.5. I'm curious whether I can attach my electrical items like my Apex controller to the inside using screws. How can I attach items to the inside of the cabinet?
