Which residential water pump to buy?

[pugboy]

what size is the irrigation hose?
it could very well be you need higher volume pump like what them farmers use 2”

[adnj]

Yea it's a system I have now.

I using one goulds pump to run my house water as well as drip irrigation for about a acre of citrus

what size is the irrigation hose?

What is needed is either:
1. Increase the volumetric capacity of the pump
2. Introduce a zone management manifold

[Chimera]

It's drip irrigation I'm using so it has 30 psi regulators to stop the 1/4 inch fittings from blowing out.

I just need 30 plus psi to reach to psi regulator

The pressure regulator on an lawn and garden system prevents damage and allows you to regulate the amount of irrigation.

To keep the pressure up, you will either need to increase the volume of water being pumped
or
Decrease the flow rate of your sprinkler system.

It sounds as if your flow is too high for the pump volume capacity. So you add a manifold and control like a Rainbird. Almost every inground system has a zone system for the same reason. They aren't cheap but they work for many years.

You can use a higher volume pump but if it's a large area with a lot of tubing, you may need two or three pressure regulators spread around the tubing. It all depends on how well you want it to work. There are tables that will tell you how many drip heads that you can use at a certain gradient with a certain size tubing of a certain length at a certain pressure. If you size it correctly, the pump will not cycle while irrigating.

How do Smart Stream jet water pumps compare to Leo/Total or a Pentax (kind of pushing it too far)?

[hindian]

Morning all. How do I know what size pump to purchase for household residential use? It’s a flat house 2 bedroom, 1 bathroom total of 6 taps throughput the building. I was thinking one of those small Pentax pumps with the smart head. Recommendations are welcomed. Thanks.

[Dizzy28]

^ I bought a 1/2 H/P Total Smarthead pump and installed it last month. Same as you..flat house with 1 Bathroom (soon to be 2 though). Apart from that its maybe 4 other taps in total. I am getting good pressure at all the outlets.

[pugboy]

total is peripheral type ?

[Dizzy28]

Not sure nah.

total is peripheral type ?

[maj. tom]

1 bath flat house is 1/2 hp. Nothing wrong with a 3/4 hp either if you know you going to use it to pressure wash and thing.

Yeah get the Pentax with smart head and add a Breakermatic 110V plug. Water Source is the service dealer for Pentax and the head so cut out the middle-man hardware in case of warranty. I have a 3/4 hp for an upstairs and it pushing 72 psi.

[hindian]

Niceness. Thanks for the info fellas…

[pugboy]

yeah that is a peripheral type, they move a little less volume than the the centrifugal type but work for small installs like yours.
they seem to be working well judging by the amount being sold on the market and cheaper than traditional pumps.

the early pentax smartheads used to burnout, not sure if they still do but seeing plenty cheaper smarthead replacements on the market

Not sure nah.

whatever you do dont take chain up and buy a 1hp for residential use because the salesman tell you is only $300 more

it will firetruck up everything.

yea I went from a 1/2 to a 3/4 and leaks like mad.
had to change a bunch of angle valves, some outside pipes blew and one inside a wall.

NOT freaking FUN

[pugboy]

why should it leak though?
once the pressure switch set to cutoff at same psi

Correct the HP shouldn't matter. A larger HP will however build pressure faster and give a better flow rate when water is being channeled elsewhere like filling a washing machine while trying to use the shower

[pugboy]

quite likely the 1hp came with a 40/60 pressure switch vs a 30/50 switch
so 10psi more which should not really be a problem unless plumbing installs are marginal

[VexXx Dogg]

in my case it was 40+ year old plumbing, so weakest points gave out. The pump was about 10 years old too, so it wasn't sending full pressure, maybe 40-50psi. The new one dropped 75+ psi from the jump.

Water pressure that you can really feel!

[X_Factor]

Slightly off topic
But anyone using those shower panels like what abc baths selling for around 1700 or so
Any issues with them?

[pugboy]

boy i have a 2 week old pentax playing the fool today
pressure switch fast clicking on and off
check valves working and i even put in a new small pressure tank to see if it would make a difference
can only try changing pressure switch now

[cornfused]

Pug the Pressure Switch is one area to check along with the tank. Fast clicking " did you try to adjust the pressure switch?

[pugboy]

boy i put in a new small pressure tank, then switched the pressure switch but still fast clicking.
turns out when the wasa pressure is just a little below the cutoff setting on the pressure switch it caused the fast cycling, also it was not high enough to load up the big pressure tank i have.
seems the supplied switch was cutting off around 40-42,so when wasa have the lines at around 35 it was fooling the switch into cutting off then coming back on with each startup pulse.
i adjusted it to cutoff at 50 and seems to work now.

i figured this out by running the pump with wasa mains locked off.

[redmanjp]

u have the pump directly on wasa line? no tank in between?

[pugboy]

nah pump sucking off tank and into house which also have wasa into it
check valve of course between pump and house

Yeah that fast clicking is usually the Switch with a Pentax , Goulds it could be about three other things

So weekend job was installing a water pump with pressure tank.
Direct feed to the pump and check valve on supply. Check valve on main.
Bled the the pump of air before turning on.
Flow was steady.
Turned on the pump and it behaves as if I have a leak on the line as the pressure on the gauge is very jumpy falling and falls very quickly even when nothing is opened.
3/4hp with pressure tank.
Pressure tank is close to 30psi through valve.
Any ideas?

[cornfused]

Daddy Dave if you're sure there are no leaks it sounds as if one of one or more of the check valves are faulty.

Pressure Dropping in a new system that is closed is a leak in the system.

[alfa]

Check valve sounding bad or something stuck in it like a pebble. Make sure you installed it the right direction as well

[Dave]

Thanks and yes. Valves are correct otherwise I wouldn't have water flowing through normal means.
To check my mains valve I even turned off mains valve and system behaved the same way.
I'll call the dealer tomorrow.
