## Questions & Answers

**Q: The toilet continues to run. I've adjusted the screw to try and raise/lower the water level but it doesn't seem to do anything. Solutions?**
A: I had the same problem; at first I was successful in taking off the cap and blowing out the valve in there that shuts the thing off.  However, my fix did not last long and I ended up purchasing a new unit (https://www.homedepot.com/p/Universal-Toilet-Fill-Valve-400ARP25/100554467) and installing that in place of the original valve assembly.  No problems since.

**Q: How do I stop moaning coming from aquasource fill valve?**
A: I had exact problem. I replaced the valve. Still had same problem. Finally realized it was the stopper leaking very slowly. I replaced it and the moaning stopped.

**Q: Is this a dual flush valve ? thanks.**
A: This is a single flush valve.

**Q: Will this work for a Penguin Model 524?**
A: Yes this will work it's universal and easy to install.
