## Questions & Answers

**Q: Does this work for mobil homes**
A: Yes. Something to ponder before you install it, though. From my experience... the reason most people want to put these in-line in the drain system of a mobile home is that the park's drain system is not draining properly, and sewage has backed up into the home :-( If that's the case -- and you're trying to prevent this -- you've got to understand that if the sewage from the park side backs up, it will close a flapper in the backwater valve... which is good! However, until the pressure of that backup is cleared / relieved -- if you are doing laundry, taking a shower, etc., your drain water will fill up your side of the line and back up into the home. So, the moral of this story is NEVER leave laundry going or other water running if you're not going to be around the home. Though I've never purchased or used one, they make hi-tech ones with an alarm... so, if it's a constant problem, you might want to consider one of those.

**Q: Can this valve be installed vertically?**
A: No it only works. Horizontally,

## Customer Reviews

### ⭐⭐⭐⭐⭐ Water feature fix
*by T***S on December 17, 2024*

I maintain a development that has a multilevel water feature outside of the entrance gates. When doing maintenance on water feature or if there is a power outage, the upper pond would drain into lower pond, lower pond couldn't handle the volume of water and would overflow onto street. This simple device prevents that from happening.

### ⭐⭐⭐⭐⭐ We had sewer smells in our home and appliances.
*by G***E on December 30, 2023*

This little pipe fixed our problem. We had constant sewer smells in our sinks and appliances. No more. I highly recommend it

### ⭐⭐⭐ Missing gasket
*by K***. on September 18, 2024*

The gasket on the flapper was missing. Didn't get to install the valve until after the return window closed so didn't notice the missing gasket until it was too late.
