Plumbing Q & A

Please reach us at service@wildcatwater.ca if you cannot find an answer to your question.

Life expectancy of a hot water tank depends on the type of unit, water quality, maintenance and installation quality.  Under ideal water and operating conditions the average water heater life span is 8-12 years.


This could be cause by sediment or scale build-up, failing dip tub,  failing gas control, or other failing parts.  Annual or semi-annual flushing of your hot water tank may help.  Under sizing of water heaters can also be a factor if the tank is also responsible for space heating or the demand for hot water has increased in your home.


This is also know in the industry as kettling, which is caused by scale and sediment buildup. This buildup causes hot spots in the bottom of the tank which creates air pockets, electrolysis and eventually tank failure.  If your hot water tank is making any unusual noises please call a professional for proper diagnosis and possible replacement.


There are many factors in the home that determine how large of a project this could be:  1. How much hot water is actually needed to run your home?  2. Will your existing gas piping support the new tank size?  3. Will your existing common vent support the new tank size?  4. Does the mechanical room have the space needed to accommodate the new tank?  5. Is a larger water heater the correct option?  Contact a licensed professional to help you answer these questions.


The short answer is yes.  As hot water tanks heat, the water expands and begin to cause pressure rise inside the tank and your piping system.  This can cause tank deformation and potential failure.  Properly installed and adjusted thermal expansion tanks act as shock absorber giving the pressure a place to be stored until either the water is drawn.


Hot water tanks should be serviced annually as per manufactures recommendations.  This allows for safety devices to be tested and replaced if faulty.  In Alberta it's suggested that your water heater be flushed every six months to help with sediment and scale buildup.


A few items that point to tank failure are: Noisy operation, no hot water or reduced amount, visible water on the floor.


Your plumbing system should be professionally inspected every 1 to 2 years,. This helps catch small problems like slow leaks or corrosion before they become expensive emergencies.


Faucet drip is typically caused by use/age, too much pressure, water conditions (hard water).  Older style 2 handled faucets sometimes have rubber gaskets/o-rings and brass seats that wear out and require replacement.  Most modern faucets now have a self contained cartridge that may need to be replaced.


This should be avoided if possible.  Oil/grease/fats cool and solidify inside your p-traps and piping causing stoppages, back-ups and stress to the city infrastructure or your septic system.  This can lead to costly servicing as your piping may need to augured/jetted.  If you have a septic system this can also cause costly repairs.


Chemical drain cleaners are not considered safe for regular use.  They're caustic and can damage older piping.  They can create toxic fumes which can irritate the eyes and lungs, and if mixed with other chemicals such as cleaners they can also produce dangerous gases.  Professional grade drain cleaning chemicals have their place and when used by competent individuals can be somewhat effective.  However, auguring and jetting are far more effective at clearing blockages in piping.


Leaking flappers and faulty fill valves inside toilet tanks along with dripping faucets are a common cause of increased water bills in the home. 


  • Improper grade/slope of the piping during install.
  • Blocked or improper venting of the drain piping.
  • Stoppages/blockages inside the drain piping.
  • If multiple drains are slow, gurgling or backing up into your home/building this could be caused by main line issues.

All of these issues may require a professional who may camera, auger and/or jet your piping.


  • Water hammer is the most common cause of rattling or banging noises in your piping system.  This can usually be fixed by installing hammer arrestors at any appliance that has a quick closing valve and/or a larger unit to service the entire home.
  • Loose or unsupported piping which can cause continuous rattling, clanking, or thumping noise when water is used.  This can be fixed by finding, securing and insulating loose piping.
  • Thermal expansion of your hot water piping which causes a creaking, ticking or tapping noise while the hot water is being used.  This can be fixed by adding a means of thermal expansion device, sleeves to let piping move quietly and ensuring plastic clips are used to support plastic piping.
  • High water pressure (over 80psi) can potentially cause turbulence, vibration and stress on piping systems.  This can be fixed by installing a pressure reducing valve.
  • Air/gases in the piping can create a gurgling or vibration in piping.  This can be flushed out of the piping however, if your home draws its water from a private well the solution may be more involved as gases may have to be removed.


  • Hardness or mineral buildup inside of fixtures and aerators.  Cleaning or replacement of aerators and fixtures are a temporary solution to a larger problem of what's in your water.  A softener or filtration system may be a better option.
  • Partially closed shut off valves.  As valves age their ability to operate properly is reduced as they become difficult to operate.
  • Malfunctioning or incorrect set (PRV) pressure reducing valves may need to be adjusted or replaced.
  • Clogged or failing pressure tank, pressure switch, well controller on your well system for those that live out of town may be an indication of your well system needing service.
  • Mineral or corrosion buildup inside of galvanized steel piping for older homes are good indicator that a whole home re-pipe may be in your future.


Poly-B piping is prone to failure as it deteriorates from the inside out often with little visible warning due to the following conditions:

  • Chemical reaction to chlorine in municipal water supplies which causes the pipe walls to become brittle, develop micro-cracks and eventually burst or leak.
  • Many Poly-B systems use poor quality fittings that are prone to cracking, slipping and leaking.
  • Hot water piping has a higher failure rate as expansion and contraction weaken the pipe and fittings.

Many home insurance companies in Canada refuse to cover homes with active Poly-B systems or they require higher premiums.  Many prospective home buyers will also shy away houses that have Poly-B piping.


 

  • How old is your home and does it have the original fixtures?  Older fixtures are not balanced, meaning that when someone else in the home is using water the pressure drops which causes noticeable temperature changes.  Installing a pressure-balancing valve or a thermostatic mixing valve on the piping for your shower may be required if you want to keep your original fixtures or upgrading to newer style single handle shower valves will help resolve this issue.
  • Mineral and/or scale buildup in hot water piping, shower cartridges, and/or mixing valves.  Cleaning or replacing shower valve cartridges may fix the issue however, a long term solution like a softener or filtration system may be required depending on how often these cartridges need to be service/replaced.
  • Do you have a tankless water heater and when was it last serviced?  These units are dependent on an amount of flow to start and stay running.  If these units are not serviced regularly many problems can arise including temperature fluctuation during operation.


  • A faulty flapper is one of the most common causes of a running toilet.  Over time rubber or plastic flappers break down due to chlorine or minerals in the water.
  • A faulty fill valve is the second cause of running toilets.  Age and wear, mineral and sediment build up are issues that will affect the way a fill valve operates.
  • An improperly set fill valve or flapper chain can also cause a toilet to run.


Plumbing leaks are not 100% preventable however, they can be minimized by taking the following steps:

  • Installing a leak detection device or a flow/usage monitoring device with an automatic closing valve or the option to close remotely.
  • Regular inspection, checking for signs of moisture around fixtures and appliances.  Look for corrosion, cracked seals or loose fittings.
  • Periodically clean aerators and fixtures to help prevent mineral build up.
  • Use quality parts during repairs and installations.
  • Hire qualified contractors for major work.


  • Maintain a minimum temperature above freezing where your plumbing is.
  • Insulate piping that is in areas that are unable to maintain temperatures above freezing.  Adding self regulating heat trace as per manufacturers instruction to piping in these areas may also prevent freezing.
  • Remove hoses from outdoor faucets and if possible replace older style faucets with the frost-free type.
  • Seal cracks and openings that could be allowing cold air to contact your plumbing.


  • Iron in your water supply which oxidizes when exposed to air will leave behind reddish-orange stains.  A whole house iron removal system is the best solution.
  • Another potential source of staining can come from existing galvanized piping or aged hot water tanks.  Replacement of these items is required to eliminate the issue.

Having your water supply tested will typically indicate the source of iron.


 

  • Hard water contains high levels of calcium and magnesium.  These minerals form scale deposits inside pipes, faucets, and appliances.  Over time, this reduces water flow and efficiency along with damaging fixtures, appliances and water heaters.
  • Hard water also causes increased soap consumption, dry skin and hair, spotty dishes and faded laundry.

Installation of a correctly sized water softener by a professional can eliminate these issues.
