Outdoor kitchen plumbing in Walnut Creek, from gas to water
We run the gas and water lines that make a backyard work: natural gas BBQs, outdoor kitchen sinks, fire pits, patio heaters, pool heaters, hot tub gas lines, propane lines, misting systems, hose bibs and outdoor water valves. We plan the route, dig or trench where needed, connect, and test before you light the first burner.
Walnut Creek backyards get a lot of use. Long, warm summer evenings make an outdoor kitchen or fire pit worth having, and cool winter nights make a patio heater more than decoration. The plumbing behind all of it should be sized right, buried right and easy to shut off.
Natural gas BBQ
A permanent gas line to a built-in or freestanding grill means no more propane tank swaps. We run the line, add a shutoff valve within reach, and connect and test the grill.
Outdoor kitchens
Gas for the grill, side burners and pizza oven, plus water supply and drain for an outdoor sink. We coordinate with your contractor before the counters go in.
Fire pit gas lines
Gas lines to fire pits and fire tables, with a shutoff you can reach safely and a run sized for the burner you picked.
Patio heater gas lines
Hard-piped gas to permanent patio heaters, so they are ready on a cool night without hauling tanks.
Pool and hot tub gas lines
Gas lines for pool heaters and hot tub heaters, which often draw a lot of gas and need careful sizing. We also do pool heater solar hookups.
Water outside the house
Hose bibs and spigots, outdoor water valves, misting systems and repairs to leaking outdoor supply lines.
Running a gas line for a BBQ, fire pit or patio heater
A gas line for a BBQ, fire pit or patio heater is a branch off your home's gas piping, usually run underground in yellow polyethylene gas pipe and brought up through a metal riser to a shutoff valve near the appliance. The hard part is sizing it so the new appliance and everything inside the house get enough gas at the same time.
Why sizing matters
Every gas appliance is rated by how much gas it burns. A furnace, water heater, range and dryer already pull from your system. Add a big grill, a fire pit and a pool heater, and an older or undersized line can starve something, usually the appliance farthest from the meter. You see it as weak flames outside or a furnace that struggles when the pool heater runs. We add up the total load and check the existing piping before we tie in.
Poly-pipe underground, metal above
Polyethylene gas pipe does not rust, which is why it is the usual choice for buried runs across a yard. It is made for burial only, so where it leaves the ground it transitions to a metal riser. Above-ground runs along a wall or under a deck are done in metal pipe and supported properly.
Natural gas or propane
If your house has natural gas, a permanent line is usually the cleanest setup. If you are on propane, or the spot is too far from the house, we install and repair propane lines too. Appliances are built for one fuel or the other, or need a conversion kit from the manufacturer, so check the grill or fire pit label before buying.
Pool heater, hot tub and solar hookups
Pool and spa heaters are some of the largest gas users at a home, so their gas lines often need a bigger pipe than a grill or fire pit. We run new gas lines to pool equipment pads, replace corroded old ones, and connect pool heaters and hot tub heaters.
Many older Walnut Creek pools have a long buried steel gas line from the meter to the equipment pad. Steel in damp soil corrodes over time. PG&E's safety notices say customers are responsible for buried gas lines on their side of the meter, and recommend having them inspected periodically for leaks and corrosion. When a buried line is in bad shape, we usually replace it with poly-pipe.
We also do pool heater solar hookups, tying solar collector plumbing into the pool's circulation so the sun does part of the heating work. In a place with as many hot, clear summer days as Walnut Creek, that is worth asking about when you replace a heater or redo the equipment pad.
Signs your outdoor gas or water lines need a plumber
Outdoor problems are easy to miss because nobody stands next to the equipment pad every day. A gas smell outside, flames that won't stay lit, wet ground with no rain, a dripping hose bib or a sudden jump in your water bill are the usual clues.
| What you notice | What it often means | How urgent |
|---|---|---|
| Rotten egg smell in the yard | Gas leak at a fitting, valve or buried line | Emergency: move away, call PG&E or 911 |
| Dead strip of lawn or bubbling puddle along a pipe route | Buried gas leak | Urgent: call PG&E, then us |
| Weak or uneven flames at the grill or fire pit | Undersized line, regulator issue, or the wrong fuel setup | Soon |
| Pool heater won't fire when other appliances run | Not enough gas supply for the combined load | Soon |
| Hose bib drips with the handle closed | Worn washer or valve seat | Plan a repair |
| Water inside a wall near a hose bib | Cracked bib or supply pipe, often after a freeze | Urgent: shut off water |
| Soggy ground near a supply line, or a higher water bill | Leak in an outdoor water line | Soon |
The California Public Utilities Commission lists hissing, dirt or water blowing into the air, bubbles in standing water and dead plants along a pipeline as signs of a gas leak. Outside, those are often the first clue. For hidden water leaks, our leak detection service can find them without tearing up the whole yard.
Summer heat, winter frost and your outdoor plumbing
Walnut Creek's weather is hard on outdoor plumbing in both directions. Summer highs usually run in the 80s with heat waves over 100 degrees, and winters are mild but often bring morning frost, with a record low of 17 degrees.
Hot summers
Summer is when outdoor kitchens, misting systems and pools get the most use, so it is when a weak gas supply or a leaking line shows up. Misting systems cool a patio on a hot afternoon, but they need clean connections and a proper valve so they don't leak or waste water. Long days in direct sun are also hard on exposed hoses and plastic fittings.
Frosty mornings
A hard frost can freeze water in an exposed hose bib or pipe. Water expands as it freezes and can split the pipe, and the leak often shows up only when you open the valve weeks later, sometimes inside the wall. During the December 2022 freeze warning, the advice was to wrap or cover exposed outdoor pipes. That still holds.
- Disconnect garden hoses before a cold night so water can drain from the bib.
- Cover exposed hose bibs and outdoor pipes with an insulated cover or wrap.
- Drain misting lines and shut their supply valve for winter.
- Know where your outdoor shutoff valves are before you need them.
- After a freeze, turn each outdoor faucet on slowly and check for leaks inside and out.
How we plan and install outdoor gas and water lines
We start with what you want to cook, heat or water, work back to the meter and the main water line, and give you a written plan before anything gets dug.
- Call and talk it throughA real person answers 24/7. Tell us what you are adding and where, and if you have a landscape or outdoor kitchen plan, have it handy.
- Site visit and load checkWe walk the yard, find the meter and main shutoffs, and total up the gas demand of every appliance, inside and out.
- Route and written priceWe map the route around patios, trees and irrigation, explain pipe choices and give you a free written estimate. Seniors get a discount.
- 811, permits and trenchingBefore we dig, utilities are marked through 811. We pull the permit where required and trench to the planned route.
- Install and connectWe lay the pipe, bring it up through risers, set shutoff valves near each appliance and connect the grill, fire pit, heater or water fixtures.
- Test, inspect, backfillGas lines are pressure tested and checked for leaks, the inspection is done where required, then we backfill and clean up.
Choosing the right setup for your backyard
The main choices are natural gas versus propane and where to run the line. Natural gas is the simplest for permanent appliances when your house already has it. Propane makes sense when gas service is not available or the spot is far from the house.
| Setup | Best for | Keep in mind |
|---|---|---|
| Natural gas line from house piping | Built-in BBQs, fire pits, patio heaters, pool and spa heaters | Existing piping must have capacity for the added load |
| Propane line from a tank | Homes without natural gas or remote parts of a property | Tank placement, refills, and appliances set up for propane |
| Portable propane cylinder | Freestanding grills and movable heaters | No plumbing, but tank swaps and storage |
| Buried poly-pipe run | Crossing a lawn or planting area | Must transition to metal where it rises above ground |
| Above-ground metal pipe | Runs along a house wall or under a deck | Needs proper support and protection |
If you want the outdoor kitchen to have a sink, plan the drain at the same time as the gas. An outdoor sink needs both a water supply and a place for the water to go, and fitting those in after the counters are built is harder.
Permits, 811 and safety for outdoor gas work
New gas lines generally need a permit and an inspection, and anyone digging in a yard should call 811 first. PG&E calls digging the most common cause of damage to underground pipelines and asks people to call 811 or visit california811.org at least two working days before digging.
- Inside Walnut Creek city limits, permits go through the City's planning and building office on North Main Street, (925) 943-5800. Saranap and other unincorporated areas use Contra Costa County.
- Gas piping should be installed by a California licensed C-36 plumbing contractor. Check any contractor at cslb.ca.gov.
- Each outdoor gas appliance should have its own accessible shutoff valve.
- Follow the appliance maker's clearances from walls, overhangs and plants, especially for fire pits and patio heaters.
- Buried gas lines on your side of the meter are yours to maintain, so keep a sketch of where they run.

Outdoor plumbing around Walnut Creek neighborhoods
The yard you have shapes the job. Hillside lots, big mature trees and older pool equipment all change how we route a line.
Hillside homes, which you find in several Walnut Creek neighborhoods, often mean terraced yards where a gas line has to climb or cross retaining walls. Older neighborhoods such as Parkmead and Larkey Park have mature trees whose roots we route around. In Rossmoor and condo communities, patios and outdoor space are often shared or controlled by the association, so check approvals before planning a gas fire table or BBQ line. Homes in Saranap fall under county permits. We sort those details out at the estimate so there are no surprises when the trench is open.

Frequently asked questions
How do you run a gas line to a BBQ?
We tap into your home's gas piping at a point with enough capacity, run the line to the grill, usually underground in polyethylene gas pipe, and bring it up through a metal riser to a shutoff valve near the BBQ. Then we connect the grill and pressure test the line. Permits and an 811 utility locate come first where needed.
Can my existing gas line handle a fire pit and pool heater?
Sometimes, but it has to be checked. Each appliance burns a rated amount of gas, and the combined load of your furnace, water heater, range, dryer and new outdoor equipment must fit the pipe size. If the existing line is too small, the farthest appliance gets weak flames. We total the load before tying anything in.
Do I need a permit for an outdoor gas line in Walnut Creek?
New gas lines generally need a permit and inspection. Inside city limits that goes through the City of Walnut Creek building office at (925) 943-5800, and unincorporated areas like Saranap use Contra Costa County. We tell you at the estimate whether your project needs a permit and handle it for you.
Who is responsible for buried gas lines in my backyard?
You are. PG&E maintains the service line and meter, but customers are responsible for all piping after the meter, including buried lines to pool heaters, fire pits and BBQs. PG&E recommends having those lines inspected periodically for leaks and corrosion. We can inspect, repair or replace them, often with corrosion-proof poly-pipe.
Should I use natural gas or propane for my outdoor kitchen?
If your home already has natural gas, a permanent natural gas line is usually the simplest choice for built-in grills, fire pits and heaters. Propane makes sense if natural gas isn't available or the spot is far from the house. Appliances are made for one fuel or need a manufacturer conversion kit, so decide before buying.
How do I protect hose bibs from frost in Walnut Creek?
Disconnect garden hoses before cold nights so water drains from the bib, and cover exposed hose bibs and pipes with an insulated cover or wrap. Walnut Creek often gets morning frost in winter, and the record low is 17 degrees. After a freeze, open each outdoor faucet slowly and check for leaks inside and outside the wall.
Do you install misting systems?
Yes. We install and repair the water supply and valves for patio misting systems, which help cool outdoor space during Walnut Creek's hot summers. A proper shutoff valve makes it easy to turn the system off and drain it for winter so the lines don't freeze. Call us to talk about where the system will connect to your water supply.
Can you hook up a pool heater to solar?
Yes. We do pool heater solar hookups, connecting solar collector plumbing into your pool's circulation system so the sun handles part of the heating. It is a good time to consider this when you are replacing a pool heater or redoing the equipment pad. We give you a free written estimate after looking at your pool equipment and layout.
What should I do if I smell gas in my yard?
Move away from the smell, don't operate the grill, heater or any switches nearby, and call PG&E at 1-800-743-5000 or 911 from a safe distance. Don't try to find or stop the leak yourself. After PG&E makes the area safe, call LeapFrog to repair the customer-owned line on your side of the meter.
Do you work with outdoor kitchen contractors?
Yes. We coordinate with your landscaper or outdoor kitchen builder so the gas line, water supply and sink drain are in place before counters and pavers go in. Planning the plumbing early avoids cutting into finished work later. Share your plans when you call and we will give you a free written estimate for the plumbing scope.
