Transcripts

- Hey everyone, John at Fresh Water Systems.

In our ongoing series

of answering frequently asked questions,

today, we're gonna talk about booster pumps.

What is a booster pump?

A booster pump is just like it sounds.

It is a pump that boosts pressure and flow.

Could be for a household,

could be for moving water from a tank,

or it could be for a commercial application.

How does a booster pump work?

A booster pump works just like a fan.

It has blades that spin around

and it boosts the air movement.

That's what a booster pump does.

It has a blade like a fan inside

and it's boosting water pressure in the same fashion.

What are the components of a booster pump?

The booster pump has very significant components

and no matter what the manufacturer is,

they're pretty much the same.

They have a motor, which makes the impeller spin.

The impeller is what moves the water.

They have an inlet and an outlet

and this particular pump has a sensing device

that helps manage and maintain a level of pressure.

How are booster pumps used?

Booster pumps are used in a variety of applications.

We go back to the root word of the product, booster.

When we are in a household that doesn't

get enough pressure from the city supply, for example,

a booster pump would be a great application

to increase pressure and flow through the entire house.

Another application might be

to repressurize water from a tank.

If you collect water into a tank

like a rain harvesting system,

in order to use it, you've gotta pump it out of the tank

and into the house, whether you're flushing toilets

or using it for laundry, for example.

You would use a booster pump to move that water.

An example of a booster pump installation or application

would be in a household where you wanna improve pressure,

you wanna improve flow rates.

In this particular instance, we've got a booster pump

in the basement that is right on the line

as it enters the house, and then the outlet

of the booster pump improves pressure to the kitchen,

to the bathrooms, and the showers.

This is one of many, many types of installations.

How do you install a booster pump?

A booster pump installs where you're gonna need

to move water from.

For example, in a household with low pressure.

You're gonna install this on the main line,

as it comes into the house.

You plug the inlet in and then,

the outlet goes back to the plumbing supply,

and you always wanna have a bypass,

just in case something happens

or the pump doesn't work right,

that you can bypass the pump

and still get water into the house.

It's very important.

The other thing that you wanna make sure you do

is have a way that you can test the pump

without having to run water through the house.

Sometimes, a leak can occur and the pump will cycle

because you have very little flow rate.

It'll turn on and run for a second and it'll turn back off.

They're typically activated by flow rate

or they're activated by pressure or both

and if you've got a leak, it's important to be able

to isolate the pump to test it,

to make sure the pump's not the problem,

and then you can solve the leak problem.

But, quite simply, to review,

you plug in the inlet and the outlet goes back

to the house pulled line

and don't forget to put a bypass in,

in case you ever have to go around the pump.

Another thing to think about in installation

is these pumps, when they run, they vibrate,

and if you hard-plumb them into,

let's say you've got copper plumbing in the house,

and you hard-plumb the pump to that,

when this thing vibrates, it's very possible

that that vibration will carry into the plumbing

and then your whole plumbing system is making noise

through that vibration.

So it's a good idea to always use a flex connector

for the inlet and the outlet, so that the pump vibration

doesn't carry into your plumbing system.

How do you size to make sure that the booster pump

is correct for your application?

A booster pump that's right for your application,

you have to figure out what you're looking for.

Do you have a two-story, four-bathroom house?

Are you moving water a significant distance?

Is the water you're drawing from quite a few feet away?

Or are you going down into a well supply, for example?

All of those items are gonna play into

which booster pump is best for you.

Some pumps have a single impeller.

It's not gonna be very good at drawing water,

so that's not what you would use

for drawing water from a distance.

Let's say you had an intake out in the pond

and you're using this pump as a irrigation pump.

If you're pumping water up a long way,

you gotta have something with a little beef,

or some horsepower, to move the water.

Water weighs eight pounds per gallon

and if you've got a one-inch pipe

that goes up quite a few feet,

that can turn into a significant amount of weight

that the pump has to push.

So, all of those elements play into which pump

is right for that application.

Under what circumstances would a person need a booster pump?

A person's gonna need a booster pump

when they need boosted water pressure

or they need higher flow rate

and it could be a variety of applications.

Pressurizing a household that's low on pressure,

bringing water out of a storage tank,

or pumping water from a lake or a pond,

or maybe even an industrial application

where an appliance or some type of apparatus

needs a lot of water at a higher pressure.

A booster pump can work in all of those applications.

Will a booster pump enhance pressure and or flow rate?

A booster pump is boosting pressure,

and in many cases, improving the flow rate.

As it's running, its fan blade is pushing water

at a faster rate, at a higher pressure.

Now, there's a pump curve to keep in mind that,

as the pressure goes up, typically the flow rate comes down.

Think about a garden hose that you put your thumb over.

All of a sudden, the water's comin' out

at a very high pressure, but our flow rate is restricted

because of our thumb.

So a booster pump works in that same fashion.

It can provide a lot of water and a lot of flow rate

at a very low pressure, so if I was just pumping water

out of the pump without any kind of restriction,

just open out to the front yard,

it's gonna provide us with a lot of flow rate.

But if I start putting this into the plumbing of the house

and I've got elbows and we're going uphill

and we're running through a kitchen faucet, for example,

then the flow rate's gonna be a lot slower

and I'm gonna have higher pressure.
