Toilet Noise During Filling?

This is a complaint that comes up regularly and our plumbers in Sidcup and Watford have fixed many of them. A toilet makes a loud noise during the fill cycle after flushing. Sometimes the noise is only a few seconds and sometimes like a toilet.

This is sometimes known as trumpeting. The name comes from that inside the valve is a small piece of nylon that the water flows through that is shapes exactly like the working end of a trumpet. And not coincidentally it acts the same way and magnifies noise.

Under normal circumstances there will be no noise as the valve is designed to allow water to flow through the valve quickly and smoothly in order to fill the cistern. After years however several things can cause the valve to fail in various ways. The buildup of hard water scale or the rubber washers, ‘o’ rings and nylon parts that rub together start to get scratched and also harden over time causing slightly loose fitting parts which then cause several problems. We recently spotted this problem at a customer’s address in Orpington whilst attending a routine central heating checkup, one of our plumbers went to the toilet and spotted it, he was more than happy to advise our customers on how to prevent this.

The final result could be the valve gets stuck closed and the tank doesn’t fill or fills slow, noises during tank filling from minor to major and leaks causing a constant dripping in the tank which then causes leaks through the overflow.

If your toilet has begun making these types of noises, then we can help. If we catch the problem early it can prevent leaks or having to fork out for a whole new toilet system. Contact us for more information.
