Changing the layout of a bathroom in a Palos Heights home isn't as simple as shifting a vanity or swapping a tub. Rerouting pipes, whether for a new shower location, a relocated toilet, or twin sinks, means getting into the guts of a house. Most homes in this area, built between the 1960s and 1990s, use a mix of copper, PVC, and sometimes older materials like galvanized steel or cast iron. These differences affect how we approach moving water supply, drain, and vent lines during a remodel.
Why Moving Bathroom Plumbing Matters in Palos Heights
Homes across Palos Heights often have hidden plumbing challenges. Many single-family houses sit on flat, clay soils with high water tables. This can make underground work tricky, especially if you're considering relocating fixtures on a slab or in a basement where drainage is crucial. If the existing pipes are galvanized or cast iron, corrosion or buildup can affect water flow and quality. Rerouting lines during a remodel is the right time to address these old materials before leaks or drain problems pop up.
Steps Involved in Moving Water and Drain Lines
- Planning: We inspect existing supply and waste lines, check venting, and map new fixture locations.
- Shutoff and Demo: The main shutoff is closed, and old fixtures are carefully removed. Floor or wall surfaces are opened as needed.
- Line Relocation: Supply lines (copper or PEX) and drain lines (PVC or cast iron) are rerouted. Drains must have proper slope to prevent backups, especially in basements with flat terrain.
- Venting Adjustments: Vent stacks often need moving to match the new layout. A missed vent can cause slow drains or odors.
- Pressure Testing: All new pipes are tested for leaks before closing walls or floors.
- Finishing and Fixture Installation: Once rough plumbing passes inspection, the space is patched, and new fixtures go in.
Common Problems With Older Bathroom Plumbing
Corrosion from old galvanized or cast iron pipes is common around here, especially in houses closer to the Calumet Sag Channel where humidity stays higher. You might notice low water pressure or orange-tinted water. Clay soils and our region's flat lot grades can slow down drains, particularly after heavy Chicago-area rains. If your remodel exposes rusty piping or slow drains, it's smart to address these issues now rather than risk bigger problems later. For full or partial repiping, we guide homeowners through options like copper or PEX and explain the pros and cons for each. Our pipe repair and repiping services fit into many remodel projects when old lines are a concern.
Basement and Slab Bathroom Remodel Challenges
Lots of Palos Heights bathrooms are located in basements or set on concrete slabs. Moving a toilet or shower in these settings is more involved because waste lines often run under concrete. Cutting through slab takes the right tools, and the high local water table means extra care around drainage and waterproofing. Sump systems and check valves help protect low-level bathrooms. If you're already planning basement work, we recommend making sure your sump pump system is in good shape and drains are clear.
Warning Signs Plumbing Needs Attention During a Remodel
- Unusual pipe corrosion or buildup visible when walls are open
- Drains with slow flow, standing water, or backups
- Old, leaking shutoff valves or low water pressure
- Mismatched piping materials (galvanized, copper, PVC) joined in awkward ways
- Odors from drains (may indicate venting issues or cracked pipes)
Spotting these signs early keeps remodeling on budget. If you notice them, check out our leak detection and repair page for more information, or our drain cleaning options if clogs are a worry.
Upgrading Fixtures, Water Heaters, and Valves
A remodel is the right time to install new shutoff valves, water-saving faucets, or an updated water heater. Local water hardness varies and can cause scale inside fixtures or tank-style heaters. Our team can discuss water heater options and recommend fixtures that handle local conditions. For new tubs, toilets, or vanities, see our faucet and fixture installation services to be sure everything fits and works right the first time.
