Start with the scope list, not the tank
Most installation surprises come from items nobody wrote down. A tank shows up, then the crew finds the vent is the wrong size or the shutoff valve will not close. The fix is a written scope before the order goes in.
On a planned job we walk the existing setup with you, note what stays and what changes, and put each item on the list. You approve the list and the price together. If the heater has already failed and water is on the floor, Water Heater Replacement is the faster path, and our 24/7 dispatch line is open for that.
What belongs on an installation scope
Ask any plumber to confirm these items in writing. We include them on every quote for a tank install.
- Tank capacity matched to your household and your busiest hour.
- Fuel type confirmed, gas or electric, with the supply line or circuit checked.
- Venting path inspected and sized for the new unit.
- Expansion tank sized and installed where the system needs one.
- Temperature and pressure relief valve with a proper discharge line.
- New shutoff valve on the cold supply and flexible connectors.
- Drain pan and drain line where the location calls for one.
- Permit handling, haul-away of the old tank and a startup check.
Planning a tank swap before it fails?
Tell us the age of your heater and where it sits. We will walk you through the scope list. Call {phone} to book a planned visit.
Sizing a tank by household
Capacity is a conversation about habits, not just headcount. This table shows what we ask for each situation.
| Household | What drives demand | What we ask on site |
|---|---|---|
| One or two adults | Showers rarely overlap | Do you run the dishwasher and laundry at the same time as showers? |
| Family with children | Back-to-back showers and laundry loads | How many people shower in the morning window? |
| Large or multigenerational home | Several fixtures running at once | Is there a soaking tub, a second bath or a long pipe run? |
| Home with a recirculation line | Hot water waiting at far fixtures | Does a pump or timer already exist on the loop? |
We size from your answers and the fixtures we see. We do not guess from square footage.
Gas or electric, and where the exhaust goes
Most tank swaps keep the same fuel, because the gas line or the circuit is already in place. Changing fuel is possible, but it adds a gas line or a new electrical run, and that belongs on the scope as its own line.
Gas units also need a venting path that carries exhaust outdoors. We check the existing vent for slope, connections and condition before we reuse any of it. A new unit does not make an old, damaged vent safe.
Expansion tank and relief valve
An expansion tank absorbs pressure swings in a closed water system. The temperature and pressure relief valve is the safety outlet if something goes wrong. Both are line items on our scope, and we explain why each one is on your list or off it.
Gas smell, and how your tank is secured
Gas smell near the heater means you leave the house and phone SoCalGas on 1-800-427-2200 from outside. If anyone is in danger or the utility will not pick up, dial 911. Call us for the repair only after that.
Ask us to check how your tank is secured. We will tell you what we see on the current setup and note it on the quote, so the new install is mounted the way you expect.
What shapes the price of an install
Here is what moves the number on your quote.
Tank type and capacity
A larger or higher-efficiency tank costs more at the supplier. Smaller homes often need less.
Venting and gas work
A reusable vent keeps the job simple. A reroute or new gas line adds labor and material.
Location and access
Garage, closet, attic and tight utility rooms each change how long the swap takes.
Permit and code updates
Bringing old connections up to a safe standard can add parts to the scope. We list them before you approve.
Permits for a tank install in Pico Rivera
The City of Pico Rivera offers an Express Permit for a residential water heater change out in the same location. That fits most tank-for-tank swaps. The contractor supplies license details with the application.
Moving the heater, changing the fuel or adding one where none existed is a different job. For anything outside the same-location change out, ask Building and Safety at City Hall, 6615 Passons Blvd, (562) 942-2000. We will tell you what we know, and the City has the final answer.
Install day, in the order it happens
A typical same-location swap follows this order.
- 1
Walk-through and shutoffs
We confirm the scope, find the shutoffs and protect the floor.
- 2
Drain and remove
The old tank is drained, disconnected and carried out.
- 3
Set and connect
The new unit is placed, connected to water, gas or power, and vented.
- 4
Safety fittings
Expansion tank, relief valve and discharge line go in as listed.
- 5
Startup and review
We fire it up, check for leaks and show you the shutoff and temperature setting.
Standards and sources behind this page
Gas safety guidance comes from SoCalGas, and permit details from the City of Pico Rivera Express Permit criteria for water heater change-outs. The California Plumbing Code is the statewide code for this work, so ask us what applies to your tank before the install is scheduled.
Questions we hear most
Yes, if the gas line, shutoff and vent pass inspection on site. That is the most common planned install. Anything that fails goes on the scope as its own line.
We ask about showers, laundry and dishwasher habits, then match capacity to your busiest hour. Headcount alone is a poor guide. Call us and we can talk through your household.
It depends on whether your water system is closed to backflow. We check on site and list the tank on the scope if it applies.
A same-location water heater change out can use the City Express Permit. Moves, fuel changes and new locations are different, so ask Building and Safety, (562) 942-2000.
Walk outside and call SoCalGas at 1-800-427-2200. Use 911 for any danger. We take it from there once the utility clears the home.
Many same-location swaps are done in one visit. Venting changes, fuel changes or access problems can extend that. We give you the plan before we start.
