The Basics of Sink Plumbing in the Bathroom

Looking at doing renovations or want to know more about bathroom plumbing? We have prepared the ultimate guide of sink plumbing in the bathroom.

It can be challenging to describe your issue to a plumber for those who don’t know much about plumbing. By understanding the different plumbing parts in your bathroom and what they do, you can more accurately describe your problems to a plumber.

This will help them get to the root of the issue quicker and provide better service for you.

Bathrooms can contain many different drains and fixtures. Perhaps more than any other room in your home. You have your main drain, bathroom sinks, sink faucets, and shutoff valves, to name a few. When you consider that you may have a bath, a shower, the toilet and a sink or sometimes two – that’s a lot of plumbing in one room.

Bathroom Plumbing Basics

Let us break the basics of sink plumbing down for you. Read on for a guide to the basics of sink plumbing in the bathroom.

Shut Off Valve

Shut-off valves are part of most plumbing systems. You can use them to quickly shut off the water from sections of your pipes for repairs and maintenance.

While there are many valves you may use, you will depend on your plumbing system. Regardless of the type you find in your home, they all serve the same function of shutting off the water.

If you experience a leak, for example, under your bathroom sink, then you can quickly shut off the valve. This will prevent further water from dripping down and damaging your vanity unit.

When you decide to replace a tap or water line, it is a good idea to replace the valve simultaneously. If your faucets are getting old, worn out and leaky, your valve may be as well.

Water Supply Pipes

Water supply pipes are those used to send potable water to your taps. They will link to the valves if you need to shut off the water.

These pipes can be made of numerous different materials and include Flexi hoses. Here are some popular options:

Galvanised Steel

These pipes are crafted from steel and then covered with a zinc coating. The coating will prevent the pipe from eroding from water flowing through it. These pipes used to be extremely popular, but superior options are now available. However, you may still find it in some older homes built before the 70s.

These pipes can last in your home for up to 50 years. After that, they are unlikely to remain an effective way of accessing water supply, and you should consider replacing them.

Copper

Copper pipes are usually used for cold and hot water systems. They used to be often installed for piping gas, although this is no longer the case. They function well both above and below ground. However, using them underground may require a protective sleeve to prevent corrosion.

Copper pipes also can last for up to 50 years. However, as time passes, they may start thinking. This can lead to tiny leaks, which can have enormous consequences. Such tiny leaks are tricky to locate and, therefore, fix.

This is largely why copper has fallen out of favour these days, giving way to plastic pipes in our homes.

PVC

PVC stands for polyvinyl chloride, and this type of pipe is currently wildly popular. They can be used in many situations, from water mains to drainage pipes.

They come in many thicknesses and colour options, which serve many purposes. For example, purple PVC pipes with black writing denote being used for reclaimed water.

When copper became less popular, PVC was one of the first plastic styles that started to be used in place of it.

The drawback of PVC is that heat can affect it. While it’s fantastic for cold water, it’s not great for hot water.

Sink Pop-Up

When talking about a pop-up sink, this refers to parts both below and above the sink. These include a horizontal rod and a tailpiece. The rod serves to pop up and down the sink plug.

If you need to unblock this drain, you will first need to remove the stopper and clean off any gunk.

P-Trap

Many plumbing fixtures contain a p-trap. The name comes from how it looks – much like the letter P.

The p-trap is the curved section of the pipe that holds a little water every time you use your bathroom drain.

The p trap seals the drain’s opening, thus avoiding nasty smells from entering your home through the pipes. However, it can be a prime place for sink clogs to build up because of the curve.

There are two sections to a p-trap: the u-bend and trap arm. These can easily be replaced if you find them broken in your sink.

Drain Waste Vent System

Basic Bathroom Plumbing Plan

The drain waste vent (DWV) system is the system that performs the crucial task of carrying away any waste from your bathroom. This includes sewage as well as water that has gone down the drain.

This is connected to the drain waste pipes and connects any sink to the main drain pipe. If you need to snake the drain in your bathroom, this is the drain pipe you will do it on.

It serves the vital purpose of maintaining the correct pressure in your bathroom plumbing. This will aid in your fixtures draining effectively.

Now that you know some of the terminologies for plumbing in your bathroom, you should be able to explain your plumbing issues better.
