HydroMinder 506 - On-going Flow-back Issue

[SelfServe24/7]

Hi everyone,

A few months ago, I started noticing an issue with my HydroMinder 506 where the chemical would not stay up at the tip of the suction tube.

I first replaced the suction tube and the foot valve, but unfortunately the problem continued. I eventually replaced the entire HydroMinder 506, hoping that would resolve it.

The new HydroMinder has now been installed for roughly six weeks, and unfortunately the same issue has started happening again.

When the site is busy, everything seems to work normally. However, after a full day of rain yesterday and very little usage, water once again pushed back into the suction tube and flowed back into the chemical bucket, eventually causing the bucket to overflow onto the floor.

Has anyone run into this before or have any suggestions on what could be causing the backflow?

Any insight would be greatly appreciated. Thank you!

It sounds like you don't have a hole in the discharge hose. There needs to be a hole above the fluid level in the tank, but below the yellow restrictor ring inside the hose. This prevents siphoning.

Drill a small 1/8" hole in the eductor discharge hose, just below the yellow ring that's inside the hose and replace the Blue foot valve with a DEMA foot valve https://www.kleen-ritecorp.com/p-12...ic-1-4-in-foot-valve-with-check-strainer.aspx
They are a much better foot valve.
