Plumbing Vent Traps

A trap - the bend in the drain below every plumbing fixture - creates a water seal that blocks sewer gases from escaping into the house. A vent prevents the trap water from siphoning away. Vents maintain equal air pressure on both sides of the trap seal. This keeps negative pressure from building up so that a slug of water running down the drain doesn’t pull the trap water out with it.

Preventing Water Leaks / Water Intrusion

Other than just having a high humidity level in the home (due to humid climate), water leaks and other forms of water intrusion into the home or building is the most common reason a toxic black mold problem originates. Below are types of water leaks and places where unwanted water can enter the home, and ways to avoid these types of water intrusion problems. Leaking Pipes: Condensation or rusting on or around a pipe is a sign of a leak. Covering cold surfaces, such as cold water drainpipes, with insulation helps to prevent condensation.

Water Heater Pressure Valve

The water heater pressure relief valve can be found on the side of the heater, and usually consists of a short pipe, which is not connected to anything. You may occasionally find it dripping. This is the mechanism by which the pressure relief valve allows excessive pressure to escape. If you find that your water heater regularly leaks water in this way, you may need to replace the thermostat, or turn it down to a more suitable temperature.

What's in your water? Lead, Bacteria

Fom basic to complete environmental water testing. If you suspect your drinking water is contaminated, the water should be tested. If your water is provided by a public system, contact the operator of the system for testing and possible disinfection. If you have an individual well, we suggest that you test your water annually. If your water sample is unsatisfactory, you should then evaluate and disinfect the well.


Lead in drinking water continues to be a serious health issue. The Safe Drinking Water Act (SDWA) was originally passed by Congress in 1974. The law was amended in 1986 and 1996, which then resulted in the banning of lead pipes, solder and brass fittings in plumbing. However, many homes, schools and buildings that stand today were constructed before this ban.

The most common way that lead gets into water is through the corrosion of pipes, according to the Drinking Water Research Foundation (DWRF). Lead can be introduced into water when the water sits too long in leaded pipes, which can then unknowingly be consumed. Since lead in drinking water cannot be detected through scent, sight or taste, the only way to confirm its presence is through proper analysis. PNWIG, LLC provides analysis to individuals, companies and government agencies.

Let our team of experts help you with your next lead in drinking water project. We offer rapid turnaround times and are capable of providing a range of lead testing services. PNWIG's lead in drinking water services Seattle, Bellevue, Redmond, Bothell, Kirkland and Renton. Prior to wording our sampling, please confirm any state-specific certification requirements with our Inspection Team or Customer Service Center.
