☀️ Why Summer Causes More Drain Backups

More Water, More Waste

At Performance Plumbing, we specialize in helping business owners, facility managers, and property managers avoid costly sewer backups, flooding, and health hazards through proactive maintenance and expert care. Let’s break down the causes and solutions for drain backups and how you can stay protected all summer long.

Why Summer Causes More Drain Backups

Tree Root Intrusion

As the soil dries out in the heat, tree roots grow aggressively toward underground sewer lines, especially older clay, cast iron, or copper pipes. Roots can break into small cracks and cause sewer backups or complete blockage of the main sewer line.

Rain, Stormwater, and Flooding

Sudden rain and stormwater can overwhelm storm drains, floor drains, trench drains, or basement drain systems—causing sewer main backups or flood damage. This is especially dangerous in areas without updated backflow or sump pump protection.

Summer Drain Inspection & Maintenance Checklist

Before summer peaks, use this seasonal checklist to help prevent sewage and drain backups:
 
As summer approaches, homeowners must prepare for the seasonal challenges that can arise, particularly when it comes to plumbing and drainage systems. Before the peak of the season hits, it’s essential to take proactive measures to prevent sewage and drain backups. A well-structured seasonal checklist can be a valuable tool in safeguarding your home against potential plumbing nightmares that can be exacerbated by increased water usage during the hotter months. From heavy rainfall to family gatherings that lead to greater stress on drainage systems, identifying and addressing potential vulnerabilities ahead of time can save homeowners from costly repairs and unpleasant surprises.
 
The checklist should begin with a thorough inspection of the property’s drainage systems, including gutters, downspouts, and exterior drains. Ensuring that these elements are clear of debris allows for proper water flow, reducing the risk of overflow during summer storms. Additionally, checking indoor drains in kitchens, bathrooms, and basements for signs of slow drainage or unpleasant odors is vital. Homeowners should also consider scheduling a professional plumbing inspection before summer, as qualified plumbers can identify underlying issues and recommend preventive strategies. By following this seasonal checklist, homeowners can enjoy the warm months with peace of mind, knowing they’ve taken the necessary steps to protect their homes from unwanted sewage and drainage complications. Clean All Kitchen Drains
Commercial kitchen drains often see the worst buildup—grease, fat, butter, oil, and starch from pasta and cooking oil all contribute to clogs. Never allow coffee grounds, soap, or acidic materials like vinegar and baking products into the sink drain.

Inspect Floor and Trench Drains

Check every commercial floor drain, trench drain, and restaurant mop sink. Remove debris, check the trap, and clean with a safe disinfectant or professional drain cleaner to reduce bacteria and odor.

Service Garbage Disposals and Sink Strainers

Your garbage disposal unit, kitchen sink drain, and sink strainer need routine cleaning to prevent clogged kitchen sink situations. Do not dispose of paper towels, napkins, coffee filters, or feminine hygiene products in these fixtures.

Check Basement Floor Drains and Sump Pumps

Your sump and basement floor drain are your first line of defense during summer floods. Test your sump pump and verify that it’s pumping to a legal sanitary sewer line—not overloaded sewers or out-of-code setups.

Inspect Toilets and Bathroom Fixtures

Inspect each plumbing fixture, toilet, flush toilet, and bathtub. Install stoppers to block solids from entering the drain line, and replace any worn valve, flange, or gasket.

Address Odors, Mold, and Contamination

Summer heat accelerates mold, virus, and bacteria growth. Musty smells may indicate water damage, leak, or sewage contamination—especially near the basement, floor, or furniture.

Perform a Full Camera Inspection

A sewer camera inspection checks your sewer lateral, drain lines, and main sewer for damage, corrosion, or leak detection issues caused by soil shifting or accessibility problems.

Test Backflow and Ventilation Systems

Ensure your backflow prevention device and ventilation are up to code. This prevents sewer gas from entering your building through drains, especially in low-use areas like utility rooms or restaurant mop sinks.

Materials and System Components to Monitor

Commercial plumbing systems rely on a variety of materials, each with their own risks:
  • Plastic and fiberglass: prone to warping in extreme heat
  • Steel, nickel, brass, bronze, iron: durable but may corrode if improperly maintained
  • Stainless steel: best for long-term use but expensive
  • Cast iron and clay: outdated, susceptible to root intrusion and collapse

When to Call for Emergency Plumbing Services

If you experience a clogged drain, kitchen sink backup, or sewer backup, contact a licensed plumber right away. Signs you need emergency service include:
  • Multiple toilet backups
  • Gurgling sounds from your sink or bathtub
  • Flooding in your basement
  • Persistent odor from floor drains
  • Bubbling from tap fixtures
Ignoring these signs can cause major health, sanitation, and insurance risks—not to mention expensive repairs.

Extra Tips to Prevent Summer Sewer Issues

  • Avoid DIY use of harsh chemical drain cleaners—they corrode pipes
  • Install a slot drain for high-volume runoff near exterior doors
  • Consider adding a vacuum pump system for heavy commercial use
  • Track all plumbing inventory and maintenance with your facility software
  • Review your homeowners or commercial insurance policy for coverage on sewage treatment, drain backup, and plumbing repairs
  • Implement seasonal home improvement strategies to improve system resilience
