Tips And TricksUpdated June 19, 2026
Remodeling a bathroom in Palos Hills means more than picking out new tile or a stylish faucet. With many local homes built 50 to 70 years ago, plumbing can slow down even the best-thought-out renovation. Hidden corrosion, outdated supply lines, and questionable drain slopes are common problems our team runs into when we expose bathroom walls and floors. Planning the plumbing early makes the difference between a smooth upgrade and a series of expensive surprises down the road.
Why Older Palos Hills Homes Need Plumbing Attention
A lot of local housing was built long before current plumbing codes. It's typical to find galvanized steel supply lines that have lost their inside diameter to rust, or cast iron drains that corrode and clog. If your home still has these materials, water flow and drainage will remain weak even with the newest fixtures. In homes still using clay-tile or cast-iron sewer lines, tree roots and heavy clay soil lead to chronic slow drains and backups.
On top of that, Palos Hills gets cold winters that freeze pipes and hot, humid summers that push old systems to their limits. Any remodel is a perfect time to update hidden plumbing before leaks or backups force the issue.
Key Plumbing Factors to Review Before Remodeling
- Water Supply Lines: Check if pipes are copper, PEX, or old galvanized. Galvanized needs to go, as it restricts flow and is prone to leaking at threads.
- Drain Lines: Cast iron and old PVC sometimes crack or clog, especially from soap and hair. Newer PVC is often needed for smooth flow.
- Shutoff Valves: Replace any seized or leaking valves. Every fixture should have an accessible shutoff.
- Venting: Bath vents often don't meet modern code. Proper venting prevents sewer gas smells and gurgling drains.
- Fixture Placement: Moving a tub, toilet, or sink means moving drains and supplies too. It is easier to plan this now than after demo starts.
Pitfalls Unique to Palos Hills
The flat terrain and heavy clay soil here make proper drainage critical. Even a minor slope mistake can leave water sitting in lines, which leads to odors or backups. Homes near Saganashkee Slough and the Cal-Sag Channel often have higher water tables, so basements and lower-level baths need reliable sump pumps and check valves. We recommend checking the sump basin and pit, even for main-floor bath projects, since water from leaks or overflow can end up there.
Hard municipal water also means any upgrades should consider scale buildup. New fixtures work best when paired with pipes free from mineral deposits. If you notice slow hot water or noisy pipes, it might be time to look at pipe repair or repiping options as part of your remodel.
What to Watch for During Demolition
Demo often reveals old repairs, rusted joints, or surprise routing of pipes. We see patchwork plumbing all the time, where copper, galvanized, and plastic are combined with makeshift fittings. This can be a source of leaks and pressure drops. Here are some signs you need a professional inspection before installing new finishes:
- Rust stains on floor or framing below old tubs or sinks
- Low water pressure or slow drains in the bath
- Noticeable sewer smell when walls or floors are opened
- Cracked, brittle, or discolored pipes, metal or plastic
- Mold or mildew around pipe penetrations
If you run into these, it is smart to pause and get the plumbing checked. Our leak detection and repair crew is used to helping homeowners spot hidden problems before the new tile goes up.
Smart Upgrades to Consider With Your Remodel
It pays to modernize more than just what's visible. Swapping out old, sticking valves and trap assemblies for new ball valves and up-to-date P-traps improves function and cuts risk of future headaches. If you are adding luxury items, like a rainfall shower or a double vanity, make sure your main supply can keep up with increased demand and your drains are sized for the extra flow.
Addressing vents is another common upgrade. Many older Palos Hills homes have insufficient venting that causes slow drainage and noise. Updating vent stacks or adding an auto-vent can eliminate these issues. And if your project involves a new soaker tub or custom fixtures, check your hot water supply. Our water heater services team can assess if your old tank is up to the task, or if a tankless upgrade will better fit your family's needs.
How Our Plumbers Help Make Remodels Smoother
We start by mapping out all old and new supply and drain runs. That way, there's no guesswork once the walls are open. We look for blockages, corroded sections, and code violations before the new fixtures go in. Whether it's a standard replacement or a total reconfiguration, we help prevent crossed lines, bad slopes, or drains with no vent. Our team also works with other trades to time everything right so you get the best results.
If your remodel reveals deep sewer or drainage problems, we can run a camera inspection and offer sewer line services, or suggest drain cleaning if you are already dealing with slow or stopped-up pipes. For new faucets, toilets, or showers, our faucet and fixture installation team ensures everything is sealed and tight from the start.
