Buyers GuideUpdated June 14, 2026
Remodeling a bathroom is a big investment and the plumbing behind the walls is just as important as what you see on the surface. Many Park Forest homes were built in the decades after World War II, and the plumbing systems often reflect their age. If you jump in without a plan, you risk leaks, sluggish drains, or even bigger problems down the line.
Old Pipes Can Slow Down the Whole Project
The original water supply lines in many Park Forest homes are galvanized steel or copper. Galvanized pipes corrode inside and restrict flow over time. Cast iron and clay drain lines, common in mid-century builds, can be brittle or partially blocked by years of buildup or even tree roots. If you're remodeling, this is the time to access and update these pipes before new tile and fixtures go in. Pipe repair and repiping is much easier during a remodel than after the room is finished.
Watch for Hidden Leaks and Water Damage
Before making any cosmetic upgrades, inspect for hidden leaks behind walls, especially around tubs, showers, and old shutoff valves. Moisture or staining on ceilings or subfloors signals a problem. Our team uses leak detection tools that go beyond what's visible. If the bathroom is above a basement or crawl space, check there as well. Early leak detection and repair saves on future repairs and protects your new remodel from water damage.
Drainage and Venting Need an Update Too
Building codes have changed since many Park Forest houses went up. Old bathrooms may have undersized drains or improper venting. A slow tub or sink drain, frequent clogs, and sewer odors are clues that something's not right. When moving fixtures or adding a second sink, your drain lines or vent stacks may need rerouting or upsizing. We regularly find outdated drum traps, missing or too-short vent pipes, and P-traps that don't meet modern standards. Our crew follows current code for every project, protecting your home from backups and sewer gas.
- Inspect all pipes for corrosion, mineral buildup, and leaks before starting demolition.
- Test drains for slow flow or gurgling to spot partial clogs or venting issues.
- Map out fixture locations and check if your current layout supports them, moving toilets or tubs needs more than just a new floorplan.
- Consider upsizing supply lines to meet modern fixture flow requirements, especially for rainfall showers or body sprayers.
- Always install shutoff valves at every fixture during a remodel for easier servicing later.
Water Pressure and Temperature Matter
Many original Park Forest homes have moderate but sometimes uneven water pressure, especially if old lines are partially blocked. If you plan to add water-hungry fixtures, test your existing supply. Your water heater's size and placement also affect performance, mid-century houses often have units that are overdue for replacement. A bathroom remodel is the perfect time to consider a new heater or to protect existing ones with a pressure reduction valve or thermal expansion tank. Our water heater services can help you decide whether to repair, relocate, or upgrade during your project.
Dealing With Drain and Sewer Issues
Flat terrain and heavy clay soil in Park Forest can put your main drain to the test, especially during wet weather. If you notice slow drains, gurgling, or sewer smells, it could point to a partially collapsed clay tile line or roots in the main. It's often best to schedule professional drain cleaning or even a camera inspection before changing bathroom layouts. If there's a pattern of backups or if your remodel lowers floor elevations (for curbless showers, for example), you might need to upgrade or reroute old sewer lines. For more serious problems, our sewer line services can address underlying defects so your new bathroom drains work as they should.
Start With Quality Fixture Installation
Fixtures are the face of your new bathroom. Upgrading a faucet, shower valve, or toilet isn't as simple as buying something new and swapping it in. Old shutoff valves may be seized, mounting holes may not fit, and some older supply lines lack the support for modern pressure-balanced valves. Our faucet and fixture installation team makes sure every connection meets current standards and is free from leaks, so your new bathroom looks good and works reliably for years.
