Hand pumps generally don't require electricity to operate and can be used for deeper flooding. Insert the hand pump to the sump pump hold, thread a garden hose to your hand pump, and you are good to go. Just wait for the water to be pumped out and begin cleaning your walkout basement.

Sump pumps and French drains are some of the most famous draining systems. These two drains have key features that separate them from one another.

A sump pump can drain out more water faster than a French drain. French drains rely on gravity to drain compared to slump pumps which are electrically powered. For uphill draining, a sump pump is more advantageous.

On the other hand, French drains do not require electricity to work. In the event of a blackout, your French drain can still function properly. French drains are also easier to maintain because of no mechanical moving parts making them less likely to break.

Another great advantage of French drains is the absence of noise. Sump pumps can be very noisy, especially if you have a powerful motor.

It still relies on your preference on which pumping system you will choose. Just remember that both drinking systems have their pros and cons. Just remember that either way, they are both great investments for your house.
