The best thing about remodeling the bathroom is that it frequently results in increasing the value of your home. Whether you want to increase the floor area or you just want a new pattern or design in the bathroom, one thing is essential: the need to re-route the plumbing system. This is primarily the reason why before you remodel the bathroom, you have to make sure that it is feasible and workable.
Steps on Re-modeling Bathroom Plumbing
- Determine the new configuration for the bathroom that will fit to your home drainage system. Although it may be possible to move any large bathroom fixture, beneath the bathroom floor are supporting plumbing system that you shouldn’t cut to install new drains. You should design your new configuration in a way that the drainpipes will run parallel to the joists and between them as well.
- Determine the requirements for remodeling your plumbing system. You may have to check your local building code first. If you are required to get a permit for the remodeling, you should be able to comply with their requirements before you start your project.
- Make room for access panels. Although sink plumbing system is accessible from the cabinet underneath it and toilet plumbing will only require lifting the toilet from the floor itself, bathtub and shower plumbing have a different story. If you have any problems with your bathtub or shower plumbing, the only way you can access them is the room beside it. If there is a sidewall in the bathroom, you may put an access panel there.
- Before you begin your re-routing project, you should turn off the water supply first which is commonly located inside the utility room. Remove the fixtures as well as the water feeds and drains. Close and seal old water feeds.
- Install new water feeds which bring the hot and cold water directly to the faucet. Do not run feeds horizontally or even drill through the studs. If you have copper feeds, tie into the old system. Or if you have a compression port system, run new PEX tubing.
- Ensure adequate slope for your drains. It is important to note that the minimum slope for waste drains is a fall of ¼ inch in every 4 feet of linear drainpipe. On sink drains, you may need to have at least a 2-inch pipe; meanwhile, showers may require 2-inch drainpipe. Toilets, on the other hand, require a larger drainpipe; preferably 3-4 inches. Do not use slopes that have more grade than the recommended for toilets; this is to prevent the water from out-running the solid waste that are in the pipe.
- Prior to placing your new fixtures, you may have to pressurize your new water feeds. You can do this by capping off the ends of the hot and cold water tubing; cap the drains as well. Turn the water source on and allow the pipes to fill with pressurized water. Leave the pressurized pipes for a few hours and check whether there are any leaks before you replace fixtures and install the fittings.
- Place your new appliances and connect them to the water feeds and the drains. Check to ensure that the hot and cold feeds are correctly installed to the faucets. Check if there are any leaks around faucets and readjust as needed.
