If your issue can't wait — or you just want a second opinion before calling a $200/hr plumber —

No sales pitch. Just straight answers about what you're dealing with and whether you need a plumber or can handle it yourself.

🚰 Most Common Plumbing Issues (San Diego-Specific)

1. Low Water Pressure

• Why it happens here: Hard water buildup in pipes (San Diego water is very hard)
• Check first: Aerator on faucet (unscrew, clean, reinstall — fixes 40% of cases)
• Cost if plumber needed: $150-400 (pressure regulator replacement)

2. Running Toilet

• Why it happens: Flapper valve wears out (especially in older homes)
• DIY fix: $15 flapper kit from Home Depot, 20 min install (YouTube it)
• Plumber cost if DIY fails: $120-200
• Hidden cost: Running toilet wastes 200+ gallons/day = $100+/month on water bill

3. Clogged Drains

• Kitchen sink: Grease buildup (San Diego's hard water makes it worse)
• Bathroom sink: Hair + soap scum
• Shower: Hair (always hair)
• DIY first: Remove P-trap, clean manually (drain cleaners damage pipes)
• Plumber cost: $150-300 for snake/auger

4. Water Heater Problems

• No hot water: Pilot light out (gas) or breaker tripped (electric) — check these first
• Not enough hot water: Sediment buildup (flush tank annually)
• Leaking: Call plumber immediately (tank failure = flood risk)
• Repair cost: $200-500 / Replacement: $1,200-2,500

5. Slab Leaks

• Why it matters in SD: Many homes built on concrete slabs, pipes underneath
• Signs: Hot spots on floor, water bill spike, foundation cracks
• Cost: $2,000-$10,000 (depends on access, rerouting vs repair)
• Urgent: Yes — can damage foundation

🏠 San Diego-Specific Plumbing Challenges

Hard Water: San Diego has some of the hardest water in California (300-400 ppm). This causes:

• Mineral buildup in pipes & faucets
• Water heater sediment (reduces lifespan)
• Soap scum in drains
• Solution: Water softener ($800-$2,500 installed) or descaling service ($150-300/year)

Older Homes (Pre-1970): May have galvanized pipes (rusts from inside). If you're in North Park, Normal Heights, City Heights — check this.

Drought Restrictions: Some older low-flow fixtures cause drainage issues. Upgrading to modern low-flow = better performance.

Tree Roots: Eucalyptus and palm roots seek water. If you have old clay sewer lines + mature trees = root intrusion risk.

🛠️ DIY vs Call a Plumber

🚨 How to Not Get Ripped Off

Red flags:

• "We need to replace everything" without clear explanation
• Cash-only, no receipt offered
• No license number on truck/website (CA requires C-36 license for plumbers)
• Pressure to decide immediately
• Quote without seeing the problem in person

Good signs:

• Licensed C-36 contractor in California
• Explains the problem and options (not just "this is what you need")
• Written estimate before work starts
• Warranty on work (1-2 years typical)
• Reviews mentioning trustworthiness (not just "fast service")
