Frequently Asked Question

Where should the check valve be on a sump pump?

In most cases, there will be a discharge pipe in the sump pump. A sump pump check valve can be found inside your sump system’s discharge line. The goal of it’s preventing the water which was simply pumped out from moving back into the sump pit when the sump pump turns off.
Probably the most appropriate place for a sump pump check valve is closer to the floor level to reduce the amount of water that drains back after every pumping cycle also it’s a handy place for effortless replacement or taking care of the valve. The check valve could be fitted down inside the sump pit but set up and also maintaining aren’t as handy making regular inspections incredibly difficult.

Most importantly, find out the area and you need to put the check valve on that area by cutting the pipe.

Which check valve is best?

The most effective valve doesn’t have any outside moving parts and is identified to be reliable and economical. As time passes, these kinds of regulators can have energy bills that are higher because the disc is still within the flow stream during operation.

Silent check valves are recognized for their peaceful closure. Always are sure to check for the flow rate. Flow pushes the disc to let forward flow.

Is check valve necessary for sump pump?

The main feature of the sump pump check valve is making certain the water actually being pumped from the sump pump pit liner and also through the release plumbing can’t drain back into the liner. You’ll want to hold in your mind pump efficiency, pump protection, and area whenever you go to use a sump pump check valve.

Is it OK to have 2 check valves sump pump?

With a second check valve in case, the 1 on the pump fails is not a great plan. If the check on the pump fails, it should be changed. Getting a second check valve will mask the issue of the very first check valve, and also cause potential contamination and water hammer at the same time.

Can a sump pump check valve be installed horizontally?

Yes, a sump pump check valve can be installed both horizontally and vertically.  Especially if they are going to drain solids they might be installed horizontally.

What is the purpose of a foot valve?

A foot valve is a type of a check valve. It is mostly installed at the bottom of a pipe line or at a pump. Although they act like ball check valves, they have an open end with a shield.

What is a float switch on a sump pump?

A float switch is a level sensor designed to alert your pump to rushing water levels in a sump pit. Mostly,  as the water level rises to a certain point, the float switch opens a circuit which allows the pump to begin pumping water up and out  the basement.

How much water pressure does a sump pump have?

Mostly between 50 and 80 PSI

The water pressure needed is usually between 5o and 80 PSI. However, if you don’t have enough water pressure, you can equally install a battery-powered backup system.

How long can a sump pump last?

The life expectancy of a sump pump depends on how often it operates. However, with proper sump pump repair and maintenance, you can expect it to last 7-10 years.  It’s important to note that you should always seek expert advice when it comes to your sump pump repair.

Can a ball valve reduce water pressure?

It’s very important to note that a ball valve only controls flow and not pressure. It requires less plumbing than a pressure regulator.

Can You Use A Pvc Check Valve With A Sump?

If you are already skilled with PVC pipe then you probably want to consider also installing a union on either side of the valve in case you ever need to replace it in the future.
