Having the proper plumbing supplies on hand can mean the difference between a quick DIY fix and an expensive service call.

We’ll explore common plumbing problems, systems, and components so you can identify issues and solutions. With the right knowledge and materials, you can tackle repairs like leaky faucets, low water pressure, noisy pipes, and clogged drains yourself. Read on to ensure you have the must-have plumbing tools and replacement parts so you’re prepared to maintain your plumbing and fixtures with confidence.

Plumbing System Basics

Before diving into materials and repairs, it helps to understand the basic components that make up a residential plumbing system. While layouts vary, most homes have three main parts – the water supply system, the drainage system, and the fixtures.

The water supply brings fresh water throughout the home. It begins at the main water line from the municipality or a private well. The main line branches into hot and cold supply lines running to fixtures like sinks, tubs, and appliances. Supply plumbing uses valves to control flow and pressure.

The drainage system removes wastewater and sewage from the home. Drain lines use gravity to carry waste downstream from fixtures like sinks, tubs, and toilets into the main sewer line or septic system. Vents allow air into the drainage pipes to aid flow.

Fixtures refer to the functional components that deliver and drain water. Plumbing fixtures include sinks, faucets, showerheads, tubs, and toilets. Knowing how to repair fixtures and their parts is an essential DIY skill.

Types of Residential Plumbing Systems

While all homes share the basic supply, drain, and fixtures framework, there are several plumbing system types and layouts.

  • Single-stack – One primary vertical drain stack for all fixtures.
  • Double-stack – Separate stacks for sinks/tubs and toilets.
  • Single-main – One centralized water main branching to fixtures.
  • Looped – Main branches into a continuous supply loop.

Understanding your home’s plumbing layout helps trace issues through the system when repairs are needed. Consulting original plans or an inspector can provide insights.

How Plumbing Systems Work

It’s helpful to understand how water enters the home, gets delivered hot and cold to plumbing components, then drains out.

The municipal water line or private well line pressurizes the main water supply line entering the home. This fresh water branches into hot and cold lines. The water heater heats the hot water supply. Shut-off valves control flow to fixtures. Drains use gravity, vents, traps, and waste stacks to remove wastewater.

Common Plumbing Problems

Knowing the most widespread plumbing troubles homeowners face allows you to diagnose issues quickly and have the right gear for repairs. Here are some of the most common problems and solutions:


Leaks encompass issues ranging from dripping faucets to burst pipes. Causes include loose joints, cracks, corrosion, freezing, high pressure, and deterioration.

For small leaks, simply tightening fittings may help. Larger leaks require replacing worn washers, seals, and gaskets in valves and faucets. Burst or ruptured pipes need immediate replacement.

Low Water Pressure

Restricted flow at taps can mean clogged pipes but is often due to issues like closed supply valves, faulty pressure regulators, or mineral buildup in showerheads and faucet aerators.

Try opening all valves, replacing regulators, or cleaning/replacing fixtures. For stubborn low pressure, pipe cleaning/replacement may be needed.

Clogged Drains

Slow draining or fully blocked drains are another nuisance. Causes include hair/debris accumulation, grease/soap buildup, roots infiltration, and collapsed pipes.

A good plunger, drain auger, or snaking tool can clear many basic clogs. Severe blockages may require disassembling and cleaning P-traps beneath sinks or opening drain cleanouts.

Noisy Pipes

Clunks and clangs from supply or drain pipes can indicate loose components or water hammer from quick valve closure. Air trapped in pipes causes gurgling.

Tightening fixtures and installing water hammer arrestors limits noise issues. Drain gurgles need venting repairs. In some cases, full pipe replacement is the permanent solution.

Toilet Problems

Common toilet troubles include leaks, clogs, loose components, poor flushing, and constant running. These issues stem from things like flapper failure, mineral buildup, debris jams, valve problems, and broken tank parts.

Replacing flappers, cleaning valves, replacing supply lines, tightening bolts, or new tank parts can address many toilet repair needs.
