Quick answer
Water heater installation means draining and removing the old tank, setting a new gas or electric unit, and connecting the water, gas or power, venting and relief valve piping. A proper install also includes seismic strapping, a drain pan where needed, and an expansion tank on closed systems. Replace the heater when the tank leaks, rusts through, or repairs keep stacking up.
Most Salem homes have a 40 or 50 gallon tank in the garage or a crawlspace, and replacing one is usually a half-day job. A new heater also brings parts of the old setup up to current practice: straps, a relief valve line that ends in the right place, and venting that draws properly.
We start by sizing. Household size, the number of bathrooms and how the family uses hot water decide whether the same size tank still fits or a step up makes sense. We also check the gas line or electrical circuit to confirm it can carry the new unit, and we look at the floor space and clearances around it.
Choosing the right size and fuel
Tank size depends on peak demand, the busiest hour of the morning when showers, laundry and the dishwasher overlap. A family of two or three often does fine with 40 gallons. Four or more people, or a soaking tub, may call for 50 gallons. Swapping gas for electric or the reverse is possible but means new piping or wiring, which we price separately so you can see the difference.
- How many people shower during the morning rush
- Number of bathrooms and any large soaking tub
- Whether a gas line already reaches the heater spot
- Panel capacity for a 240-volt electric circuit
Venting a new gas water heater correctly
A standard gas heater sends exhaust up a metal flue that relies on hot gases rising. The vent pipe needs a steady upward slope, the right size, and tight joints so exhaust cannot spill back into the garage or house. We check the draft hood with the burner running. When a new tank sits taller than the old one, the vent connector often needs to be rebuilt to keep that upward pitch.
Seismic straps, drain pans and expansion tanks
The Willamette Valley sits in earthquake country, and a full tank weighs several hundred pounds. Strapping it to the wall framing keeps it from tipping in a quake and tearing the gas or water lines loose. We set two straps at the proper heights and anchor them into studs.
Tanks in a crawlspace or over finished space get a drain pan piped to a safe spot. When a pressure regulator or check valve closes off your system, a small expansion tank absorbs the water that grows as it heats, which keeps the relief valve from dripping.
Removing the old tank and pulling the permit
We shut off the gas or power and water, drain the old heater, disconnect it and haul it away. In Oregon, water heater replacement generally needs a plumbing permit, so when one is required we pull it and set up the inspection. Before leaving, we fill the new tank completely before lighting it or turning on power, so the elements never fire dry.
Warning signs
Signs it is time for a new water heater
- Leak from the tankWater seeps from the tank body or bottom seam rather than from a fitting or valve.
- Rust at the baseFlaking rust or a stained floor around the bottom of the heater shows the steel is corroding.
- Repeated repairsYou have replaced several parts in the last couple of years and something else keeps failing.
- Not keeping upThe household has grown and the tank runs out of hot water before everyone gets a shower.
- Old age and noiseThe heater is well past its expected life and rumbles loudly from hardened sediment.
- No straps or bad ventThe tank stands unstrapped or the vent pipe slopes the wrong way and needs rework.

Water Heater Installation: what Salem homeowners ask
How long does a water heater installation take?
A straight swap of a gas or electric tank in the same spot usually takes three to five hours, including draining the old one and testing the new one. Moving the heater, converting fuel, or rebuilding a vent adds time. Once the tank is filled and heating, plan on about an hour before you have a full tank of hot water.
Does a new water heater need an expansion tank?
If your home has a pressure regulator, a check valve, or a backflow device on the water line, the system is closed, and heated water has nowhere to expand. That pushes pressure up and can make the relief valve drip. An expansion tank gives the extra volume a place to go. We check your system and add one when it is needed.
Can a water heater be installed in a Salem crawlspace?
Yes, and many homes here already have one there. A crawlspace install needs a clear path in and out, a drain pan with a line to a safe spot, a vent route for gas units, and enough room to service the tank later. We look at access first, because some crawlspaces are too tight to work in safely.
Should I switch from a gas to an electric water heater?
It depends on your home and goals. Electric tanks need no venting and can go in more places, but need a 240-volt circuit and heat back up more slowly. Gas tanks recover faster but need a flue and gas line. If you are thinking about going electric, a heat pump water heater is worth comparing too.
What temperature should a new water heater be set to?
Most households do well around 120 degrees, hot enough for showers and dishes while lowering scald risk and energy use. Some people prefer a little higher for a large family or a dishwasher without a booster heater. We set it with you after installing and show you where the dial is, so you can adjust it later.
