Winter Plumbing Tips

When temperatures drop in cold and snowy weather regions, winter plumbing takes the top spot as one of the most important maintenance tasks for your rental property. And thankfully, there are common-sense steps to “winterize” your property each season in order to prevent major plumbing issues and expensive repairs.

Top Cold Weather Plumbing Problems

Temperature fluctuation may be a regular part of changing seasons, but it can create a perfect storm of problems where your plumbing is concerned. Falling leaves and debris, extra cooking, and freezing temperatures are a recipe for common plumbing issues: 

  • Clogged drains
  • Unattended leaks creating mayhem
  • Increase of sediment and rust in the Water Heater 
  • Broken garbage disposals
  • Frozen pipes and pipe bursts

Even for regions where snow and icy weather may be rarer, a cold wave could catch you and your renters off guard. Be prepared for common cold-weather plumbing problems. Informing and empowering your renters is a key step in protecting your rental property from damage and costly repairs.

Clogged Drain Prevention and Repair

The top causes of clogged drains haven’t changed much over time, and they often become problematic during winter holidays when more guests flow through homes, using the showers and sinks more regularly. Remember: hair, trash, soap, uncleared mineral deposits, and large food items will bring drains to a standstill. 

Other specific don’ts for your drain include:

  • Car fluids
  • Coffee Grounds 
  • Eggshells 
  • “Flushable” cat litter
  • “Flushable” wipes 
  • Grease
  • Oils
  • Paper towels
  • Produce stickers

DIY Clearing Your Drain

If it’s too late, and the drain is already backed up, you can try a few quick methods. Eye and face mask protection are a smart move to avoid direct contact with bacteria, mold, chemicals and other waste products. Popular Do It Yourself options for drain clearing include:

  • Home Recipe: Pot of boiling water down drain, ½ cup vinegar, ½ cup baking soda down drain, close drain cover for 15 minutes, open and pour a final pot of boiling water.
  • Use Your Hands or Pliers – Remove the drain cover and often you’ll see and can remove the problem.
  • Plastic Drain Clog Remover: Use this 24-inch, plastic, flexible barbed tool that easily grabs trash, hair, and food. Finish with a pot of boiling water down the drain.

Give Leaks Your Immediate Attention

If you’ve left a slow leak until the cold months, it’s time to jump on that repair right away. Not only do leaks waste the precious resource of water, but they will undoubtedly add to your utility bill.  The main problem with leaks in winter weather is expansion in the pipes should the water freeze. When that happens, the leak grows into a bigger issue that could result in additional repair costs. 

DIY Leak Fixes for Accessible Pipes

In many circumstances, a leaky pipe may require a plumber, especially for external piping or wall piping. However, if you’ve identified the pipe in an accessible area like under the sink, there are some quick methods that will provide a temporary solution. 

Always start by turning off the water main, turning on the faucet to drain the pipes, and thoroughly drying the area. Then try these Do It Yourself steps to fix your leak:

  • Replace the P-trap or other accessible pipe under the sink – make sure you have the right fit and double-check the alignment.
  • If you’re using PVC and copper pipes, consider using a Pipe Clamp to cover the compromised portion of the pipe. These are widely available and easy to install, as long as you have the same size clamp as your pipe.
  • Cover a hole with Epoxy Putty – this is a pretty good temporary fix. Just make sure you use protective gloves, and wait about 10 minutes after applying before turning on the water

Drain & Flush The Water Heater 

Hard water inevitably leads to the buildup of sentiments like calcium and magnesium, which in time develops into rust. Remember, this is the water that will flow into your home for drinking, cooking, and cleaning. With the cold weather, you’ll want to make sure you fix this problem and provide safe and clean water for your household. 

Realize that standard water heaters have a lifespan in the range of  7–12 years, depending on the level of maintenance given. Try this method below, but know that the sun may be setting on your water heater.

How To Drain the Water Heater

Put safety first as you deal with electricity, gas, and hot water. Then takes these routine steps to drain and flush the sentiment buildup from your water heater:

  • Turn off electricity or gas source – follow the manufacturer instructions
  • Turn off the water supply – This is the cold water valve to your water heater
  • Turn on the hot water – Open a faucet and leave it on while draining the water heater
  • Connect a hose and drain the water heater into buckets
  • Flush cold water through the water heater again by opening the cold water valve
  • Close the drain valve of the water heater 
  • Refill the water heater tank
  • Turn on the electricity or gas source 

Never want to deal with draining the water heater tank again? Consider a tankless hot water heater system, which provides endless hot water on demand.

Fix a Clogged Garbage Disposal

Winter holidays often bring along larger meals and more people eating them. Plumbers frequently get calls in winter to clear, repair or replace garbage disposals. Follow the same list of items to avoid as with other drains, and remember to avoid these additional items which regularly cause chaos for garbage disposals:

  • Banana peels
  • Chemicals like Drano – These can damage the disposal parts
  • Fruit pits
  • Paint
  • Pasta
  • Potato peels
  • Rice and beans
  • Seafood shells

DIY Garbage Disposal Repair 

Try these Do It Yourself steps if it’s too late, and you’re dealing with a backed up or broken garbage disposal:

  • Is there a brief humming sound coming from the disposal? If so, check the circuit which may have been tripped. If it’s still humming but not working properly, proceed to the steps below.
  • Press the garbage disposal Reset button – typically on the bottom of the unit.
  • Insert an Allen Key in the slot next to the reset button, turn it both back and forth to free any blockage until you feel the blades turning freely.
  • Turn on the water and check that the sink is draining

Don’t be discouraged if you need to call a plumber on this one. Sometimes the grease and food backup is significant and may require a drain snake or similar. 

Frozen Water Pipes – What to Do

Frozen pipes are a cold-weather plumbing issue that you do not want to encounter when the temperatures take a polar plunge. They can cause property damage – especially if they burst – and headaches for you and your renters. The American Red Cross notes that frozen pipe problems usually occur when pipes and water lines get exposed to extreme cold and lack of heating and insulation of both indoor and outdoor water lines. A good winter maintenance plan can be key in preventing this issue before it starts.

However, if you suspect a problem, check your pipes for a freezing issue by turning on a faucet. If water only trickles out, be sure to check other faucets throughout the property. A slow-flowing faucet is a key indicator that one or more pipes or areas have been affected by the cold weather.

Do It Yourself steps you can try to thaw frozen pipes:

  • Warm the pipes up close with the help of a hairdryer, a heating pad, or towels soaked in hot water.
  • Heat exposed pipes by turning on a space heater.
  • Turn up the temperature on your thermostat to defrost frozen pipes in the walls and other unexposed locations.
  • Keep the faucet open so the melting water flows to melt other areas of the pipe.
  • DO NOT use any sort of open flame or gas-powered device!
  • Don’t stop until your water flows at its full, usual pressure.

Steps to take to prevent frozen pipes in the future:

You and the tenants of your rental property can also live by these helpful tips to avoid frozen pipes:

  • Make sure the water line entry area is warm and insulated.
  • Open kitchen cabinet doors to allow heat to reach otherwise isolated pipes.
  • Leave faucets running at a trickle to relieve pressure buildup and prevent frozen pipes.
  • Consider asking your utility provider if it can offer a small billing adjustment for running your water to prevent pipes from freezing. It could save you and your renters money and trouble!)
  • Consider a tankless water heater for an endless hot water supply as a way to avoid frozen pipes and keeping hot water flowing – without waiting for a tank to heat up the next batch.
