Plumbing problems you can fix yourself. Step-by-step from licensed plumbers.
Plumbing guides for homeowners in Montclair and across the Inland Empire, written and reviewed by Sweetwater Plumbing's licensed plumbers (CSLB #889182). Each guide tells you when to stop and call (909) 312-4516 or text (909) 247-6791.
Many plumbing problems don't actually need a plumber.
In more than sixteen years of plumbing in the Inland Empire, we've noticed something: a meaningful share of the calls we receive could be solved by the homeowner with the right step-by-step instructions. So we wrote them down.
These guides cover the most common situations our customers in Montclair, Ontario, Upland, Rancho Cucamonga, Chino, and the wider Inland Empire run into: clogged drains, water leaks, water heater issues, sewer line warning signs, and emergency shut-off procedures every homeowner should know before they need them.
Each guide is written by our licensed plumbers from real field experience, not stock content. We tell you when DIY makes sense and when it's time to stop and call a professional. There's no upsell, no scare tactics, no marketing fluff. Just the steps that work.
If a guide doesn't solve the problem, or you'd rather have us handle it from the start, call (909) 312-4516 or text (909) 247-6791. We're based in Montclair and answer calls 24/7.
DIY has limits. Know them.
Smell gas? Leave the house first, then call SoCalGas at 1-800-427-2200 and 911 from outside.
Some plumbing situations require professional tools, licensing, or experience to handle safely. Call us right away if you encounter any of the following:
- Active water leak you can't stop by shutting off a fixture valve or the main water shut-off.
- Sewer backup into a tub, shower, or floor drain: this indicates a main line problem that needs professional equipment.
- No water in the whole house, even though the main shut-off is open.
- Slab leak symptoms: warm spots on the floor, the sound of running water with all fixtures off, a sudden spike in your water bill.
- Hot water that's rusty or smells like rotten eggs: rusty water usually means the tank is corroding; a rotten-egg smell only in the hot water usually comes from the anode rod reacting with the water. If you smell rotten eggs in the air, treat it as gas: leave first, then call SoCalGas at 1-800-427-2200 and 911 from outside.
For anything on this list, call (909) 312-4516 (phones answered 24/7) or text (909) 247-6791.
