Whirlpool tub fills via jets...OK?

[AHI in AR]

I had a first today. The whirlpool tub had deck mounted valves and no spout. With a little bit of hesitation I opened one valve and found the tub started filling up through the jets. In 13 years I've never seen this. There is no brand name on the tub, so I can't look it up and see if this is acceptable.

It seems like there's a pretty good potential for cross contamination, but I don't know if there is a check valve or other system employed because the front of the tub was sealed. Definitely seems goofy.

Anyone know if this is okay?

Fill-Flush System. They claim there is a back-flow feature.

I still think it's evil.

Thanks, Jerry. I looked at the site and it appears you are right.

Still seems odd though.
