Sump Pump Basics

OLYMPUS DIGITAL CAMERA

A recent inspection in Parker Colorado brought this issue to mind.
Sump pumps are self activating electrical pumps that protect homes from moisture intrusion. They are usually installed below basement or crawlspace floors to remove rising ground water and surface water runoff before it can enter a building. Pumps should be maintained and equipped with all necessary components in order o ensure their reliability.
A pit, known as a sump pit or sump trench, is dug at the lowest part of the basement floor to capture and contain any water within the ground adjacent to the structure. A sump pump normally sits at the bottom of, or beside the sump pit, and expels water through pipes that carry the water outside and away form the building. The exit pipe opening should be at least 5 feet from the foundation.
Some maintenance tips:
In Colorado where there is not a great deal of moisture or high ground water tables, a sump pump may sit inoperable for a length of time. Here are a few things to keep in mind:
*The pump should be kept clean and free of debris
*Make sure the float is not jammed and can move freely up and down.
*The pump can be tested, if dry like the one pictured, by pouring water into the pit to see if it activates.
*Maintenance should be done annually or when the home is sold. An inspector will not normally test a dry system. It may be advisable to request a seller to have a plumber check the system if it has not been used regularly should there be a concern. The fact that the pit is dry does not necessarily indicate a problem with the operation of the pump or system.

Unwanted Intruders

These are some examples of intrusions into buildings I have found during inspections in Denver and Aurora Colorado. The first image shows an active bird’s nest in the soffit of the home, and the second is an apparent entry and exit point for squirrels. It is very important to monitor the outside of your home to prevent this type of activity, and to make and take immediate steps to seal any opening which may be used by birds or rodents. When animals set up shop in the attic or walls of a home or building, they can cause damage to the building components such as the rafters, joists and stud-walls. Squirrels and mice have been known to chew through wiring and pipes presenting any number of problems for the owner. An infestation like one of these also presents obvious health risks from droppings deposited in the internal cavities of the building. Rodents and birds do not need to create an obvious breach in the structure like those illustrated here. They can enter through gaps in the siding and soffit area, fascia, and roof vents. If you become aware of the possibility of an intrusion of animals, a professional exterminator can be retained to both remove the birds or rodents, and seal the points of entry into the home to correct the problem. Our family experienced a squirrel attack to our attic this spring, and the professionals were able to remove the squirrels humanely, relocating them to open space away from our home, while I sealed up the siding and vents to prevent any further intrusion.

Open Ground in Electrical Outlet

OLYMPUS DIGITAL CAMERA

During a recent inspection in Parker Colorado, I discovered that the electrical system had an issue with an outlet not being wired properly. The photo above illustrates how the issue was discovered.

During an inspection, I use a plug-in circuit tester that will test the circuit via three neon lights. I use the Sure-test brand tester which is highly respected in the industry. It will test for an open neutral, lack of a ground, wires on the wrong terminals, and no power. A typical outlet has three holes built into it. The shorter straight slot is the “hot” lead. The longer straight slot is the “neutral” lead. The slot that looks like a small circle hole is the ground. If the outlet is wired properly, both green lights on the Sure-test will light. In this case, only the green light on the left lit when the outlet was tested. This indicated the grounding wire was not connected properly.

Grounding is extremely important to both the safety of the occupants and protecting the property in the event of a fault or lightening strike. The grounding wiring in the system carry current to the grounding rod outside. If any of the outlets or the panel is not grounded properly, this important safety system is breached. In this case, it was recommended that the electrical system by inspected by a qualified licensed electrician to be evaluated.

Furnace Inspection

On a recent inspection in Highlands Ranch Colorado, I was impressed with this furnace. The home is 10 years old, and this was the original unit. As you can see in the photos, it was recently serviced in OctoberOLYMPUS DIGITAL CAMERA of 2012. The unit is immaculate, and the burners work correctly as the flames are bright blue with little yellow color in the flame. This indicates that there is the appropriate gas/ air mixture during operation. It is clear that this owner has kept up yearly maintenance and the technician involved has done quality work. Its important to check the furnace unit for regular service and to check it during operation whenever possible.

Window Wells: Covering and Egress

This is  photo of a typical window well in an area home recently inspected in Castle Rock Colorado. It has a safety cover over it which is very important, and is of sufficient size to allow egress from the basement area in the event of a fire or other emergency. Window wells at a depth of 44 inches or greater, should be fitted with a ladder which is at least 12″ wide, to provide easy escape for anyone needing to use the window to exit the home. In this case, the depth of the window well is approximately 40 inches, so a ladder is not required. This is a good thing to check in your home, to make sure your family can use a basement window to exit the building if a situation arises in which it becomes necessary.OLYMPUS DIGITAL CAMERA

Trip Hazard – Walkways and Driveways

OLYMPUS DIGITAL CAMERAOLYMPUS DIGITAL CAMERA

This is a common issue that we find on homes 10 years or so and older. This home is located in Parker Colorado. Trees that were small when planted, create problems with concrete slabs and foundations as they reach maturity. In this case, the tree is now lifting a section of the sidewalk over 1 inch above the section next to it, and it now is beginning to create a safety hazard. In a situation like this, the section of the sidewalk can be removed and replaced, have additional material applied over it to level the surface, or in some cases, lifted and leveled by mud jacking. The tree should be removed at this point. In this case, it is within 6 feet of the foundation, and it can be expected to cause further issues down the road. Its always best to keep trees and large shrubs at least 10 feet from foundations or concrete surfaces.

 

Shake Shingle Roofs – Wear, Maintenance and Repair

OLYMPUS DIGITAL CAMERA

During a recent inspection in Parker Colorado, this roof was observed. Normally, a wood roof is not walked on during an inspection as it can cause damage to the shingles, but in this case the owner requested I check the roof from on top. The home is approximately 20 years old and the shake shingles are showing a great deal of wear. Some are split and or missing. This roof may still be repairable, although the cost and difficulty to repair this many damaged shingles makes it a borderline case for replacement. In this case, we recommended the roof be replaced to our client prior to sale as the unrepaired areas of the roof will likely continue to deteriorateOLYMPUS DIGITAL CAMERA rapidly at this stage. In many cases, wood roofs can be repaired and the roof certified against leaks for 5 years by qualified roofing contractors.

Water Damage from Leaking Clothes Washer Drain

This is an interesting problem we encountered on a recent inspection in Aurora Colorado. The area around this drain pipe which services the drain on the clothes washer in this home indicates that leaking has occurred for some time. When I tested the subfloor with a moisture meter, it did not indicate the OSB board was wet at the time of the inspection, but it is clear there is a moisture problem of some kind.  In the inspection report, we requested the client have a plumber investigate further.

As the photos indicate, no leaking is visible around the drain in the laundry area. What the plumber determined was that on some occasions, during the wash cycle, the washing machine sets up a vibration which has worked a joint in the drain line loose.  Small amounts of water flowing through the drain leak intermittently causing the staining to occur, but it is a small amount and drieOLYMPUS DIGITAL CAMERAs quickly. This situation points to the fact that it is always a good idea to periodically check drain lines when toilets, sinks, dishwashers or other systems are in use to make sure there is no leak occurring. Sometimes the seepage can be very small and not readily noticeable.
