How to Fix a 16″ Rough Toilet Flange: Tips from Plumbing Experts
If you’re having trouble installing a toilet or replacing a damaged flange, you may need to know about the 16″ rough toilet flange, which is a common type of flange used in older homes. Unlike newer flanges that have a standard 12″ offset from the wall, a 16″ rough toilet flange has a 4″ extra offset, which requires a longer toilet bowl and a deeper rough-in measurement. While this type of flange can work well if maintained properly, it can also cause problems if it cracks, leaks, or becomes misaligned over time. In this blog post, we’ll share some tips from plumbing experts on how to fix a 16″ rough toilet flange and ensure a secure and leak-free installation.
1. Identify the Problem
The first step in fixing a 16″ rough toilet flange is to identify the problem. This may involve removing the toilet and inspecting the flange for cracks, corrosion, or erosion. If the flange is worn out or damaged, it may need to be replaced with a new flange that matches the rough-in and diameter of the drainpipe. If the flange is misaligned or recessed, it may need to be shimmed or raised to make it level with the floor surface. If the flange is loose or wobbly, it may need to be anchored or secured to the subfloor.
2. Remove the Old Flange
The next step is to remove the old flange, which may involve cutting it away from the drainpipe with a reciprocating saw, a hacksaw, or a chisel. This can be a messy and time-consuming process, especially if the flange is made of cast iron or PVC. Once the flange is removed, you need to clean the drainpipe and the surrounding area with a wire brush, a scraper, or a solvent. Any debris, rust, or residue may affect the fit and seal of the new flange.
3. Install the New Flange
The third step is to install the new flange, which should be a 16″ rough flange that matches the diameter and height of the drainpipe. You may need to use a wax ring or a sealant to create a tight seal between the flange and the toilet bowl. You should also secure the flange to the subfloor with screws or bolts that are long enough to reach the studs or joists below. Make sure the flange is level and flush with the floor surface, and check for any leaks or gaps.
4. Test the Toilet Bowl
The fourth step is to test the toilet bowl, which should sit firmly and evenly on the flange without rocking or shifting. You should also check the gasket or wax ring to make sure it seals the drainpipe and prevents any sewage or odors from escaping. If the toilet still leaks or wobbles, you may need to adjust the flange or shim the base of the toilet with plastic wedges or tiles. You should also tighten the bolts or nuts that secure the toilet to the flange, but not too tight, as this may crack the porcelain or create stress on the wax ring.
5. Consider Hiring a Professional Plumber
The fifth step is to consider hiring a professional plumber if you’re not confident or experienced in working with plumbing fixtures. A licensed and insured plumber can inspect your flange, diagnose any underlying issues, and recommend appropriate solutions that meet local building codes and safety standards. A plumber can also save you time, money, and frustration by using specialized tools and techniques, such as hydro jetting, video inspection, or trenchless repair. Moreover, a plumber can guarantee their work and provide you with a warranty that covers any defects or failures.
Conclusion
In conclusion, fixing a 16″ rough toilet flange can be a challenging task that requires some plumbing skills, tools, and knowledge. However, by following these tips from plumbing experts and being patient and careful, you can install or repair a flange that supports your toilet bowl and prevents any leaks, odors, or damage. Remember to always use a 16″ rough flange that matches your drainpipe and rough-in dimensions, and to secure the flange to the subfloor with screws or bolts.
