Sprinkler System Booster Pump Addition

Hi,

I am going to install a booster pump on my irrigation system and have a few questions before i get started.

The picture shows my system and where i plan on adding the booster pump. My trouble area, which i need the booster for, is in the front of the house (3 Zones). From the well to my 3 valves is 267 feet.

The booster i purchased will kick on when the psi reaches less than 38psi.

Is the placement i propose ok? I can easily get power to it.

I am going to install it ouside and remove it for the winter, what type of install should i do? I know i will need unions to remove. Do i need pressure reducers? Any kind of typical install help with components needed would be wonderful. I have looked around and could not really find anything.....

Thank you. Any advice/support you guys can supply would be appreciated, i have the pump in hand.

Yes, that looks like a good location. It will boost the pressure to the three trouble zones in the front yard and it's close to the house to make running power relatively easy.

Typically you would not need a pressure reducer but you may if the pump boosts the pressure too much. Some residential spray heads work best with 30 psi and mist when run at higher pressures. I would try the pump without a pressure reducing valve first and see if you have troubles. You may only have an issue with one zone or just a few emitters and in that case you can replace individual pop-ups with pressure reducing ones.

Thank you for the confirmation of location.

How does this picture look (Below)?

When i blow out the system, the manual ball valves will be useful. Anything else that might be nice to add? Maybe a built in pressure reader by the pump?

I really do appreciate it.

Placing the pump on an "off shoot" like you've drawn provides another benefit. You'll have some flex in the pipes so you'll be able to move your unions apart making it easier to install and remove the pump each season.

A pressure gauge would not hurt or at least install a "T" fitting with a threaded plug so you can screw in a gauge later if needed.

Was just thinking, should I put the pressure reducer before or after the pump?
