When your hot water tank is left in operation for a long while without any tender loving care, things can go pretty bad for it. That's why you need a guide to draining hot water tanks from Winnipeg experts. Sediment of various minerals builds up and clogs it, so the heating elements works far less efficiently, and your energy bill skyrockets in turn.
To prevent this inconvenient occurrence, you should make a point of draining and flushing your household unit at least twice a year, or approximately every six months. But, if you are like us, you have no idea about how that messy job is supposed to be properly done. So, to solve the mystery, we called up our friends in Winnipeg who are experts on hot water tanks, and asked them for some advice!
First, prepare everything you need for drainage
Turn the heater off to avoid a hazard. If your it is powered by gas, you will need to turn its switch to “pilot”. This will keep the pilot light still on, but the no heating will be going on anymore. If instead your heater is an electric one, find the switch that supplies the system with electricity and switch that off. This switch is typically found above the heater, in a switch board.
Give the water that is already in there some time to cool down. Depending on how big the unit is, it may take a few hours or about half a day. Then stop the liquid supply. Find the valve for cold water intake and turn it off. It is usually located at the top of the heater, along the relevant inlet path.
Then choose any one hot water tap in your home and turn it on, and leave it running until everything from the pipes is gone. Finally, locate the pressure relief valve on your tank and open it up. it may hiss when you turn it; this is nothing to worry about.

Drain the container all the way
The best way is to use a garden hose, if you can drain it into an outdoors space. If it is located in your basement, and the basement has an operable drain, you can go straight for that.
If you live in an apartment without those options, try placing a big bucket or such underneath and then working in increments according to the dish’s capacity. You can empty the bucket into the toilet, but only the water! If any sediment falls in, it will damage the toilet porcelain and the sewage system. Instead, dump it into a plastic bag and take it out with the rest of your trash.
If you opt for a hose, make sure it is long enough. Also, find some kind of mesh to catch the sediment. If you are draining the content into a lawn or garden, cooler is always much better. Remember that the location of your unit will influence the hose setup!
If it is installed above ground level, just stretch the hose outside and let gravity do its thing. If it is underground, get a mini pump from a hardware/ home improvement/ gardening tools store.
Hook the hose onto the main drain valve with a wrench, and let all the liquid out. If it will go into a drain, catch some in a bucket to assess the amount of sediment.
Flush the dirt out
Check your bucket or mesh for any sediment, and if there is a fair lot, flush the tank. Hook the hose off, keep the pressure relief valve and end tap off, and get the cold water intake going. Fill the container up, then drain it again. Repeat until there is no more sediment coming out.
Finally, disconnect the hose for good, fill up the unit again, turn on the pressure valve, and the gas or electricity feed. Provide regular maintenance, to make sure the heater is working properly. Also, switch the heater off when there is enough hot water, and keep it off while showering or bathing – otherwise you may overload the thermostat, which may cause the tank to explode.
