You can find out almost anything on the internet. A classic example of this is the Toiletology 101 website by Kay Keating - “A free course on toilet repairs to save water and money”.

This unique resource promises “Almost everything you ever wanted to know about your toilets! And some things you probably never knew you needed to know”. Many years ago it helped me repair a fault in my toilet’s cistern. Last weekend, with my toilet constantly dripping, I remembered the site and was able to rectify the problem, thanks in part to the understanding of toilet plumbing gained from reading Toiletology 101.

Even if your loo is faultless, there’s plenty to interest those into gadgets and learning how stuff works. Useful information freely available … its what makes the internet great.
