Plumbing in Mobile Homes

Plumbing in manufactured homes is a great DIY project. The home plumbing system is more simplified in mobile homes, which helps when it comes to getting down to business.

The connection of the main water supply usually lies under the edge of the home, near your outdoor hose bib. The supply lines are usually found near the middle of the home or on the one side of the home that depends on the layout of the water system of your home. Plumbing pipes are placed within the walls of a manufactured home but these are straight through the floor.

How to Turn Your Water Off?

You should be knowledgeable as to where the pipes are located in your home so you may be able to turn your water off in case of emergency. If you’re able to shut the water of your home quick as you can, it will save you from disaster and any other inconvenience. Therefore, the main stop valve should be outside of your connection so that you may get easy and quick access.

Supply Lines

Supply lines are the smaller water pipes (3/8-1 inch) that are working into the home. If your home has white, cream or a medium grey pipe for your water supply, you should replace them as most local regulations don’t recommend them and some have banned them altogether. There are also some drain pipes that are made from copper or PVC. To assure quality, you should get the grade right on drainage pipes because too much grade may cause as much issue as too little. A 1/4 to 1/2 grade per every foot is ideal for the supply of water in your home.

Ventilation Pipes

Ventilation pipes ventilate and help to keep the proper pressure or vacuum throughout the plumbing in your home. This means that it keeps water in all the right places equally.  It’s also very important for the supply and drain lines, but you should exercise proper ventilation to assure proper results. Plumbing systems require air and water to give the best results. You should keep in mind that a single ventilation pipe can’t give you the demanded results, but you must use a dry vent. These vents are very helpful for the air flow into the drains.

Poly-butylenes Pipe

Poly-butylenes were considered helpful in this regard so it’s used in all types of homes, including manufactured homes built from 1970’s to 1990s. These pipe is user-friendly, as it can be broken down in case of bleach in your water or leaks. This type of pipe is still used in most of the houses despite having what is deemed as ‘low-quality’ material. If you are using this type of pipe for drainage in your mobile home, be sure to replace when needed.


PVC is a plastic plumbing pipe that’s primarily used to transport high pressured water to the demanded area. You can get it in several sizes of your needs. It’s used to handle the cold water because the hot water will make it lose. It can be purchased in white or grey. 



PEX is also very helpful in this regard because it works as cross-linked polyethylene pipe that’s first manufactured in the 1920s, but has become more popular in recent years because of its high quality. It’s the same outer diameter to shape as copper does. It has a little edge over PVC pipes because it can be used for both the hot and cold water.  

How to keep Pipes together?

It’s very necessary to keep the pipes in order to connect each other in a proper way. Here are the four simple ways to keep your pipes from freezing and avoid damage.

1.  Keep Your Heat On

Heating bills can get ridiculous but the most surefire way to keep the pipes from freezing is to make thermostat running by keeping your house nice and warm. The problem occurs when most people drop their thermostat way down to avoid a big bill.

2.  Let Faucets Drip

You should turn your faucets on just enough to dribble a little water out. Opening faucets will relieve pressure to get rid of pipe bursting. The water will run easily from your pipes all the times.  

3.  Keep Pipes Exposed

You should have cabinet doors in your kitchen and bathroom open that make it simple to keep pipes warm. It will help in transportation of warm air to get easy access to the pipes and to make the flow of water easier.

When water freezes, it expands, which puts a lot of stress on pipes, causing bulging, cracking and leaking. It can cause serious water damage particularly when the pipes are hidden behind the walls. You should make the flow of water in the pipes faster and easier to save yourself from the disturbance of shortage of water.
