Summer Outdoor Plumbing: Preparing Your Philadelphia Yard for the Season

← Back to Blog

As Philadelphia warms up and backyard season officially kicks off, your outdoor plumbing deserves the same attention you give the rest of your home. Whether you're firing up the garden hose for the first time, planning weekend cookouts, or getting your sprinkler system running, a little preparation now prevents costly emergencies later. Here's your complete guide to getting your outdoor plumbing ready for a Philadelphia summer.

Inspect and Test Your Hose Bibs

Your outdoor faucets — also called hose bibs or spigots — take a beating during Philadelphia's freeze-thaw winters. Before you hook up that garden hose, take a few minutes to check each one:

• Turn on each faucet slowly and watch for leaks around the handle, spout, and where the pipe meets the exterior wall
• Check for reduced flow — weak pressure could indicate a cracked pipe inside the wall that partially froze over winter
• Look for dripping when off — a faucet that won't fully shut off wastes water and can erode your foundation over time
• Inspect the vacuum breaker (the small cap on top) — this backflow prevention device keeps garden chemicals and dirty water from entering your drinking supply

If you notice any leaks, even small ones, don't ignore them. A cracked pipe behind the wall can cause thousands of dollars in water damage before you even realize there's a problem. That's a call worth making sooner rather than later.

Get Your Sprinkler System Up and Running

If your Philadelphia-area home has an in-ground irrigation system, spring startup is a process — not just flipping a switch. Here's the right way to do it:

1. Open the main valve slowly. Turning it on too fast can cause water hammer, which stresses pipes and fittings. Open it about a quarter turn at a time over several minutes.
2. Run each zone manually and walk the yard looking for broken heads, misaligned sprayers, or zones that aren't activating.
3. Check for soggy spots in the lawn — a soft, muddy area near a sprinkler line usually means an underground leak.
4. Adjust head positions so you're watering grass, not sidewalks and driveways. Philadelphia's summer water rates make every gallon count.
5. Reprogram your timer for summer watering schedules. Early morning (before 6 AM) is best to minimize evaporation.

If you had your system professionally winterized (blown out with compressed air), a spring startup inspection by a licensed plumber ensures everything is sealed and functioning before you rely on it all summer.

Outdoor Kitchen and Grill Plumbing

Outdoor kitchens have become increasingly popular across the Main Line and Delaware County, and they come with real plumbing considerations. If your outdoor kitchen includes a sink, ice maker, or gas grill connection, here's what to check before your first summer cookout:

• Test water supply lines for leaks — fittings can loosen from temperature cycling over winter
• Run water through the drain to make sure it flows freely and the P-trap still has water in it (a dry trap lets sewer gas escape)
• Inspect gas line connections to your grill or cooktop — apply soapy water to fittings and watch for bubbles, which indicate a gas leak
• Check your outdoor water heater (if you have one) for proper operation and signs of corrosion

Address Yard Drainage Before Summer Storms

Philadelphia averages about 3.5 to 4 inches of rain per month during summer, and when those afternoon thunderstorms roll in, they hit hard. Poor yard drainage doesn't just create puddles — it can flood basements, erode foundations, and destroy landscaping. Here's what to look for:

• Standing water within 24 hours of rain — healthy drainage should clear surface water within a few hours
• Water pooling near the foundation — this is the biggest red flag for potential basement flooding
• Downspout discharge — make sure gutters are clear and downspouts direct water at least 4–6 feet away from your home
• French drains and channel drains — if your property has them, check that inlets aren't clogged with debris from winter

Many older Philadelphia neighborhoods — from Manayunk to Media — have properties with grading issues that send stormwater toward the house instead of away from it. If you've noticed recurring basement dampness or foundation moisture, a drainage assessment can identify the root cause and a permanent fix.

Pool Plumbing Prep

If you're opening a pool this season, the plumbing side of pool startup is just as important as balancing the chemicals. Before filling:

• Inspect all visible plumbing — pump connections, filter housings, return lines, and skimmer baskets
• Check the pump for signs of seal failure (water or rust stains underneath)
• Make sure the backwash line is clear and properly directed
• If your pool has a heater, have the gas connection and heat exchanger inspected before firing it up

Pool plumbing problems discovered after the pool is full and running are significantly more disruptive (and expensive) to fix. A quick inspection before opening day saves headaches all summer long.

Protect Against Backflow

Here's one that most homeowners don't think about: backflow prevention. When you connect a garden hose to a sprinkler, pressure washer, or chemical sprayer, you create a potential pathway for contaminated water to flow backward into your home's drinking water supply. This is called backflow, and it's a real concern — not just a code technicality.

Most modern hose bibs in the Philadelphia area have built-in vacuum breakers, but they can fail over time. You can also buy inexpensive hose bib backflow preventers at any hardware store. If your home's plumbing system doesn't have a dedicated backflow prevention device, especially if you have an irrigation system, it's worth having one installed by a licensed plumber.

When to Call a Professional

Some outdoor plumbing tasks are straightforward DIY — connecting a hose, adjusting sprinkler heads, or cleaning debris from drain grates. But others require a licensed plumber:

• Any suspected leak behind a wall or underground
• Gas line connections or repairs (never DIY)
• New outdoor faucet or spigot installation
• Sprinkler system repairs involving main lines or valves
• Drainage regrading or French drain installation
• Backflow preventer installation or testing

In Pennsylvania, plumbing work that connects to your home's water or sewer system must be performed by a licensed contractor. It's not just about doing it right — it's the law, and it protects your home's resale value and your family's safety.
