Key Plumbing Verifications Before Remodeling > 자유게시판

Before you dive into a kitchen remodel, bathroom upgrade, or a full‑house renovation, the plumbing system is one of the most critical foundations you must verify. A concealed leak, an old pipe, or a water heater that is too small can transform a chic new area into an expensive disaster. Below are the critical plumbing checks every homeowner ought to conduct before the first shovel strikes the ground.
1. Find and examine the main shut‑off valve The main shut‑off acts as your safety valve—the spot where you can halt all water supply to the house. Make sure it is easily accessible, not buried deep in a crawlspace, and that it opens fully. Close it, 名古屋市東区 トイレリフォーム 格安 then open a faucet at the house’s lowest point; if water still comes out, the valve is jammed or damaged. Replace or repair it before any work starts.
2. Check the main water supply line Look for corrosion, pinhole leaks, or unusual rust stains along the line that feeds into your house. Focus especially on joints and fittings that might have been welded or soldered decades ago. If you find any damage, replace the affected portion or have a licensed plumber assess the whole line.
3. Inspect for hidden leaks in exposed piping Even if no water is visibly dripping, low‑level leaks can cause damp walls, mold, and structural damage. Use a moisture meter or a basic water test: shut off the main valve, then slowly restore water while checking exposed pipes for dampness or condensation. A leak detector can also pinpoint hidden issues in walls or floors.
4. Confirm water pressure and flow rates High pressure may damage fixtures, whereas low pressure can cause new bathrooms to underperform. Attach a pressure gauge to an outdoor tap to read the pressure (ideally between 40 and 60 PSI). If the pressure is outside this range, contemplate installing a pressure‑reducing valve or upgrading your plumbing to meet the new demand.
5. Inspect the water heater’s condition and capacity A water heater that is too small for the renovated space can cause cold showers, especially if you’re adding an extra bath or a new kitchen. Check the unit’s age, look for rust or leaks on the tank, and confirm that the temperature setting is appropriate. If the unit is older than 10 years or the new layout demands more hot water, plan an upgrade to a tankless system or a larger tank.
6. Inspect shut‑off valves on individual fixtures Each sink, toilet, and shower should possess a working shut‑off valve. Turn each one on and off; if any are stiff or fail to close completely, replace it. This simple step will spare you future headaches if a leak ever occurs.
7. Check that all venting systems remain intact Proper venting lets air into the plumbing system, keeping drains running smoothly. Inspect vent stacks, especially if you’re adding new fixtures or extending existing ones. A blocked vent can cause slow drains and unpleasant smells. If you suspect a blockage, have a plumber clear the vent pipe.
8. Examine the underground or buried lines If your renovation involves relocating heavy appliances or installing new foundations, the underground lines may be at risk. Use a pipe‑locating device or request a map from your local utility company. Consider trenching, shielding, or replacing old cast‑iron lines that could fail under new loads.
9. Inspect water quality issues that may impact fixtures Hard water can create mineral buildup on faucets and showers, cutting their lifespan. Test for hardness and pH. If the water is very hard, you might need a water softener or a maintenance plan for calcium‑scale removal during the renovation.
10. Verify compliance with local building codes Many municipalities mandate permits and inspections for plumbing work. Even if you’re only doing basic checks, having a licensed plumber verify the system before you start keeps your renovation legal and safe. This step also protects you from future liability and ensures future resale value.
11. Detect outdated or non‑compliant pipe materials Older houses frequently contain lead, galvanized steel, or unlined copper pipes that can be unsafe. Do a lead test if you suspect lead or employ a pipe inspector to detect hazardous materials. Replacing these pipes early in the renovation will protect your family and lower long‑term maintenance costs.
12. Arrange for future expansion or upgrades If you foresee adding more bathrooms, a home office with a printer, or a new kitchen island, verify the plumbing can handle the higher demand. Talk with a plumber about future plans to size pipes, add shut‑off valves, or install a booster pump if needed.
