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. ## Frequently Bought Together - WDI AquaSource Original Fill Valve Replacement for 1.28 GPF Toilets (98923, 312795, 352027, 395280, 12293) by WDI Technology Co.
