a 1hp Gould deep well jet pump has what 'I' call a flow control valve on the discharge side of the pump-(it looks sorta like a pressure regulator-has a 5/16" threaded bolt in the top of it).
I was told that this controls the amount of water sent back down the 2" casing to the 'jet' to use to suck water up to the jet.
my question is HOW to properly adjust this valve/regulator?

any advice would be appreciated!
thanks.

Hi.

I never seen what you decribe used for a well pump.

You have a two pipe jet pump? The jet portion of the pump is down in the well, or at the well head.

The device you descibe is not used for the purpose you were told. As far as I know, it may have been put there to reduce the gallons per minute the pump feeds the home. The pump is still going to work at its rating regardless, by filling the well tank.

What does your pressure gauge read, cut in psi /cut off psi

I doubt the well is making more the 80 psi with out that reducer, and can probably be removed.

i think that if you use the above link it will show a picture of the pump i am referring to - with the regulator valve.
yes the jet is 20' down the well , with an other 45' of down pipe with a foot valve on the bottom.
it is about a 125' well with 2" galvanized pipe casing.

 

OK I got this from Goulds. What are you trying to do, or what is the issue?

All deep well jet pumps require back pressure
to operate the jet assembly. To insure we have
the required back pressure or drive water
pressure we must use a pressure control valve
or some type of flow restrictor in the discharge
line. The valve must be located between the
pump and the first discharge port. It is best to locate it as
close to the pump as possible. Failure to install and adjust
a pressure control valve will result in loss of prime during
peak usage such as filling a washing machine, bathtub or
using outside hose bibs.

What is the model flow control????

If you only have a 2" casing, it sounds like a packer system. I am not familiar with these, but its not rocket science.

Here all the info you need on adjustment and the different kinds of pump systems.

There are alot of good well guys on here that will help you further if you need additional help.

Hope this helps.

thank's for the link. i think that the info will help. yes-it is what 'gould' call a packer system
we took the pump off of a 130' well with a 2" pvc casing & the jet was 50' ft down.
put the pump on a 125' well with 2"galvanized casing & the jet is 20' ft down.
'I' figured that the difference in the 2 wells would require an adjustment of the back pressure.
the chart in the link gave me some numbers

 

Seriously, you should consider not giving any more advice on the well forum, you don't know what you're talking about.

 

You should set that regulator at 40-45 psi. There are ways to maximize the amount of water you get out of the pump, but normally on that particular pump 40-45 psi when the pump is running should suffice.

That regulator controls the amount of water being backfed to the well to drive the jet. That is why when the pump is running, even if the tank pressure is at 30 psi, the pump gauge will read 40ish psi, which is the jet pressure.

 

What are you talking about?


I told the poster I never seen it. Whats wrong with that?

I asked him a question. If it was a two pipe the jet assembly is not at the pump. Is that correct? Anything wrong there?

OK. Who knows what people install. He could of had a PRV valve installed on a regular jet pump. I have seen lots of crazy stuff. Again. OP did not give enough info.

This was a question.

I have not seen a well make more then 80 psi. I did not state as fact but said I doubt it.


TW I suppose your posting history is all accurate with no flaws? I am a member just like you. I am here to assist best I can.

Read post #4 then the OP's post #5. I think he thanked me for the link, and I feel I helped him.

Next time please PM me if you have an issue.

If you have never seen one, why even comment? It should be obvious from his description of a 1-HP deep well jet pump that it is the regulator. Every deep well jet pump I have ever installed required a regulator. I don't even think one would work correctly without one.

I have seen plenty of pumps make 80 psi. If you dead-head that pump it will make over 100 psi at the regulator, I have seen some set for 60-80 psi on/off.

Not trying to get into a **** match with you on here, your advice is not always wrong, but why comment on something of which you know nothing of.

To the OP, sorry for hijacking your thread.

 

I did ask for 'any 'advice.
the link posted did give me some info that i did not have.
thank's again to both of you

 

We're having an issue with water flow from a new Red Lion Jet Pump for our deep well. I saw you were talking about the control valve and that's one of our trouble shooting things we need to look at. We aren't sure what the best setting is. Our kitchen sink get up to an aggressive trickle, but it fades, stops, starts again, and the PSI on the pump doesn't get above 12. Our control valve is all the way counter clock wise. Is that bad?
