Benefits of Crawl Space Sump Pump

If you’re still not convinced regarding why sump pumps will benefit you, we have made a list of the top 3 benefits of having a sump pump in your home –

Prevents Flooding

If you live in a climate where frequent rainfall and storms occur, then you are probably not unfamiliar with the incidence of having your basement flooded. This may happen in any climate in the case of a sudden storm. A sump pump will help you prevent such incidences.

As the sump pump will drain away all the water trying to pool in your basement, your house will remain untouched and dry. Besides, it will prevent valuable objects from getting destroyed, and your home structure from being ruined.

Gets Rid of Mold

If your basement is frequently flooded with water, no matter how fast you try to dry it, mold will begin to accumulate over time. This is a source of potential harm for both you and your home. Getting rid of mold can also be a lengthy and energy-consuming process.

Therefore, it is better to stop the problem at the roots. By installing a sump pump, you will no longer have to worry about flood water, and consequently, mold.

Ensures Safety

Water and electric lines are never a good combination. When floodwater enters your basement, any electric lines there will be sabotaged and might result in a fire. The fire can be potentially life-threatening. Just the simple case of installing a sump pump can get you rid of all these problems.

How to Pick the Perfect Sump Pump for Crawl Space

The market has a lot of sump pumps available. In order to find the best sump pump for crawl space, you need to look at the following factors;

Type

There are two types of sump pumps in general – a pedestal pump and a submersible sump pump. With the submersible sump pump, you need to dig a hole in the basement to get it installed. However, these are usually noise-free and get water drained whenever it reaches a specified level.

A pedestal sump pump can be installed above the ground. It performs the same function as a submersible pump, butit makes a lot more noise.

Power

One important thing to consider while buying a sump pump is the power you might be needing. If you need protection from rainwater frequently, you should consider getting a model with a powerful engine.

That means if you live in an area where you face storms and floods constantly, gambling with a relatively weak sump pump might not be the best choice.

Flow Rate

Another very important thing to consider is the flow rate. It can be specified as gallons per minute or gallons per hour. What this means is how much water a sump pump can drain in a minute or an hour. It is a major indicator of efficiency.

While it is common to think that the higher the flow rate is, the better the model will be, that is not necessarily the case. Some areas observe very few cases of excess accumulation of water, and thus having a machine with a higher flow rate just adds to the cost and electricity bills.

Besides, they are prone to get burnt out more easily.

Size

Make sure that the pump fits well into your pit. To do that, get all the relevant measurements before you start looking. The crawl space is usually very cramped, so if you get one size too big, you might have a hard time getting it fitted.

Durability

To find out if your pump is durable enough to bear the burn of all the hard work in the coming years, take a look at the materials it is made of. Generally, sump pumps can be made with plastic, cast iron, or stainless steel.

Among these, plastic models are the most cost-efficient but also scores the least in terms of durability. Cast iron is the most durable, but the problem is that it is a heavy material.

Besides, cast iron is prone to corrosion and rust, making it incapable of staying in a good condition while working with water. But if cast iron is coated in epoxy resin, the issue of corrosion goes away.

Stainless steel is lighter than both of these materials and offers resistance to corrosion. Besides, it gives a sophisticated look and can last for much longer than either plastic or cast iron. Therefore, looking for models made of stainless steel or epoxy resin-coated cast iron might be agood choice here.

Switching System

Another thing you need to look at is the switching system of the model. Two types of switching systems can be found in most sump pumps – one is automatic and the other is manual.

With the automatic switch, there is a floater that starts the motor as soon as it is pushed by the water ata specificlevel. This switching system helps homeowners stay worry-free, as they do not need to turn the switch on every time there is a storm.

And with a manual switch, you need to manually turn the switch on and off through a toggle switch. This system is more energy-efficient than an automatic switching system.

Which type of switch will be the right choice for you depends on the kind of climate you live in. If you face frequent heavy rainfall, then it is best to get an automated switch as it will not require you to turn the switch on every time. Other times, a manual switch helps save a lot of energy and cost.

Installing Guide for Crawl Space

To install a sump pump in a crawl space, go through the following steps –

Choose a Spot

Instead of choosing an arbitrary spot, find where the water starts pooling the fastest and choose that spot to install the pump.

Get Digging

Usually, crawl spaces are smaller than basements.So, take great care while digging to not end up hurting yourself.

Install the Basin

Install a basin thatfits nicely into the pit you have dug. Try to incorporate a liner in the basin to get rid of any waste. Some basins also come with lids that get the job done.

Install the Pump

While keeping the pump straight, start installing it. Most sump pumps come with detailed information regarding theirinstallation process. Try following it step by step.

Get Some Drainage Lines

Drainage lines are required to get any debris out that might otherwise clog your system. Install these too.

Start Testing

Test the new system by adding some water to the basin. Make sure beforehand that all the power lines are well away from the basin.
