If you are planning and preparing with rough plumbing then there are a few common mistakes that you will want to avoid. Knowing beforehand what they are can help to make your process go smoothly.
1. Check With the City and Make a Design
Many times your town or city will need you to do a rough plumbing design and have it approved. Other times, homeowners may not even be able to do their own plumbing work so getting this approved ahead of time is a great idea. When making your design to get approved you want to make sure that you do it right the first time. Basically it needs to be a drawing that shows your vent and pipe lines only as if they were the only things in the bathroom. You have to make sure that you are including the pipe sizes, dimensions, the fittings and any vent piping. This design not only helps you with ensuring that you are allowed to work on your plumbing and are up to code, it also helps you throughout the process to get an idea of what you need to be doing as well as saving money on materials in the long run.
2. Clean Outs
Make sure that any clean out that you are doing is in the direction of the flow. If you are not doing this, you will run into problems later on that could end up costing you a lot of money to repair. Also, making sure that you leave enough room when designing them so that you can fix any future problems is important.
3. Double Check Electricity and Water Lines
When you are working on the rough in plumbing sketches you will be putting in where the water lines are and where they attach to appliances or fixtures as well as where the outlets will be. You have to make sure that when you are planning that these two aspects will not get in the way of each other and that they can be hooked up where you actually are planning them to be. Many times people plan but do not check to make sure it is possible to run the water where they wanted to.
3. Plan for Enough Space
One common mistake that people make when doing rough plumbing planning is that they do not leave enough space between appliances or fixtures. If you do not plan ahead and actually measure out, you may end up with the toilet too close to the sink or the shower and making it uncomfortable. Also, you will want to make sure that you are measuring, buying the fixtures like the vanity or toilet and then measuring again to make sure they will fit.
You can easily avoid these mistakes with thorough preparation and planning and making sure that you are in line with the local building codes. Putting effort in to begin with can really help to avoid problems down the line with the project.
