Lemarg, a top flood damage restoration company, has all the tools and equipment to help bring your home back to its normal state. A sump pump is basically a device used to pump out water. In the event that you may need one for your home, this information would come in handy.

  1. What types of sump pumps are available?

Sump pumps generally come in two types: Submersible and Column (Pedestal)

Submersible sump pumps as the name implies are usually set in a large sump pit. Because they are placed under water, the noise level will be at a minimum and the motor will cool faster while working

Pedestal sump pumps do not require a sump pit and the motor is placed above the sump pit. Generally they last longer than submersible pump. The only downside being that they pump less water.

  1. What type of float switch do I need?

There are three main alternatives on the market to choose from: tethered, vertical and electronic float switches. A tethered switch is best used for deeper sump pits with a larger diameter; the switch allows for adequate pump cycle period, hence the motor cools off quickly. Vertical switches are best suited to narrow and shallow sump pits, and unlike the former, they will start the pump more often. Electronic switches are much smaller and require a small sump pit. You are advised to avoid using an electronic float switch if there is any likelihood that it may come in contact with water from a laundry machine or wash sink. This will prevent soap scum from making contact with the switch.

  1. How much horsepower should my sump pump have?

The higher the horsepower the faster the pump rate and vice versa. But this also translates to higher power usage. If your sump pit gets filled easily, then you should opt for a sump pump with a higher horsepower.

  1. What material should my sump pump be made of; cast iron or thermoplastic?

Cast iron pumps are generally tougher than thermoplastics, though both are built for durability and long time usage. However, sump pumps made of cast iron distributes heat from the motor much better and  cool off faster. On the flipside, thermoplastic sump pumps are cheaper.

  1. Do I need a check valve?

Check valves help to prevent the back flow of water in the discharge pipe back into the sump pit. Having a check valve means you won’t have to pump out the same water twice. So yes, you actually do need a check valve.

  1. Do I need a battery-operated backup pump?

It is wise to additionally install a battery operated backup pump just in case you need one when there is no power, especially if you stay in an area susceptible to flooding.

You are encouraged to test your sump pump periodically to check that it still functions properly. Contact your local flood damage restoration company for professional fire, water and mould restoration services.
