How NOT to Install a Water Filter

We recently investigated the cause of failure of a water filtration unit that cracked and caused an extensive amount of water damage to residential dwelling.  During the course of the investigation, it was determined that a whole house water filter unit had been installed in a cabinet beneath the kitchen sink.  This location is perfectly acceptable as were the piping connections that were made to connect the unit to the cold water supply line.  However, when the upper and lower halves were assembled, the pieces were put together with pipe joint compound.  This is absolutely unnecessary and amounts to an improper installation.  The filtration unit comes with an O-ring that is intended to fit between the halves and seals any gaps while preventing water leakage.  Although the unit failed as a result of over pressurization,  the presence of pipe joint compound indicated that the filtration unit had been improperly maintained.  The failure of the unit is shown in the photographs below.

Vehicle Recalls

Recently, some major manufacturers have recalled some of their vehicles for some serious defects. First, General Motors has recalled 1.4 million of its vehicles for an oil leak that can result in an engine fire. This particular recall is also part of a series of recalls for this same problem; that were initiated in 2008. At one time, the problem was thought to have been caused by leaky valve cover gaskets. Currently, GM is saying that drops of oil can be deposited on a hot exhaust manifold and ignite. But, GM is not saying what the source of the oil is; only that they are working on a repair. The vehicles that are involved in this recall are:

1997-2004 Pontiac Grand Prix

2000-2004 Chevrolet Impala

1998-1999 Chevrolet Lumina

1998-2004 Chevrolet Monte Carlo

1998-1999 Oldsmobile Intrigue

1997-2004 Buick Regal

All of the above vehicles are equipped with 3.8 liter, V6 engines. Owners should take their vehicles to their GM dealerships for repair. For additional information, owners can contact GM by calling 1-800-222-1020 for Chevrolet vehicles, 1-800-762-2737 for Pontiac, and 1-800-521-7300 for Buick.

Second, GM isn’t the only car maker with problems. Nissan is recalling 46,846 model year 2013-2016 Altimas and 2016 Maximas. This is in addition to the already recalled 5,500 model year 2016 Maximas. These vehicles are all equipped with 3.5 liter, V6 engines. The problem with these vehicles is that an O-ring installed between the fuel tank and fuel sending unit was improperly installed and can leak in the event of a crash. Fuel in the presence of an ignition source can result in a fire. Nissan has already begun notifying owners. Owners should take their vehicles to a Nissan dealer for a free repair. For additional information, owners can contact Nissan at 1-800-647-7261.

Third, BMW is recalling approximately 86,000 Mini hatchbacks for a steering problem. The vehicles that are involved are 2002-2005 Mini Cooper, Cooper S, and 2005 Cooper and Cooper S convertibles. These vehicles can lose their electro-hydraulic power steering assist and as a result, drivers can find it more difficult to control the vehicle. It is possible for a crash to occur if the driver cannot apply the extra effort required to steer the vehicle and maintain control. Mini will begin notifying owners on or about December 1, 2015. Mini dealers will also inspect and replace components as necessary free of charge. For additional information, owners can contact MINI customer service by calling 1-866-825-1525.
