Plummer
In short
Plummer is a common English surname and a professional title for a person who installs and repairs water pipes and heating systems.
In plain words
A plumber fixes leaks and keeps water flowing through your home. They also look after toilets, sinks, and hot water tanks. They make sure your pipes do not burst or get blocked.
A simple example
If your kitchen sink starts leaking water onto the floor, you call a plumber to fix the broken pipe. They will use special tools to tighten the joints or replace the damaged parts.
Why it matters
Without plumbers, homes would not have clean running water or working toilets. They prevent water damage and ensure sanitation in buildings.
Easy to mix up
Do not confuse a plumber with a painter, as they both work in homes but handle completely different tasks.
