On 2015-12-29 by (mod) - possible to use a 2-line jet pump with only the suction line by plugging the pressure line.

Yes but ... it depends on the pump brand and model. Some 2-line jet pumps can be modified with a factory kit to convert to one-line.

You cannot (usually) just plug the pressure line as there are internal changes needed too. It's a bolt-on parts modification.

I have a two line jet pump, not the original. I believe the original one had an air tank attached to it. The one installed now does not have an air tank.

Problem...the pressure will not get above 30 pounds, pressure switch was adjusted to come on at 18 and go off at 30... Mother in law has been living with this for ten years...would like to fix this. CanI convert the 2 line to a one line jet pump with the venturi at the pump not in the well?

I have a shallow well with a two line set up after i prime the pump it will build up to max pressure setting and shut off as it is set to .

then turning on the faucet letting the water run with decent water pressure until low pressure setting kicks in the pump .

On 2015-08-18 by (mod) - pump type and capacity need to match the needs & well

Dennis, you can use any pump brand with your well: it is the pump type and capacity that you need to match: 1 line or 2 line jet pump, horsepower. However take a look at the piping connections for your old and for your replacement pump; you may be able to select a model that requires very little rearranging of piping.

I have a 2 line jet pump and want to use it for a shallow well application. Can I plug one of the lines off?

On 2015-06-21 Tom S

Do these systems have a vent pipe? We have a two line system. There is another pipe sticking out of the ground, not connected to anything I was told was a vent.

Recently the system is having a difficult time filling the pressure tank. It seems to wait until the tank pressure is quite low before kicking on and then take a long time to build up enough pressure in the tank to shut off. The pressure at the pump is around 50 psi.

I was wondering if the vent hose may have gotten clogged preventing the system from working properly or perhaps the flow rate isn't high enough to service the system, although this is the first time this has happened in the 11 years we've been here.

Any thoughts on what might be the cause? I'm hoping to not have to put in a new well.

On 2015-05-19 by (mod) - it has to be either the pump, or the foot valve/jet assembly

Tom

RE: I know it has to be either the pump, or the foot valve/jet assembly in the well.

I read that to mean that you are confident that we don't have a problem with the well running low on water - a poor flow rate.

I don't think that a bad foot valve or clogged strainer is likely to limit the maximum pressure that a pump can reach. Usually that pressure limit is from a damaged pump impeller, low voltage, failing motor / bearings, or sometimes water running or leaks in the piping system.

I suspect an impeller problem. Before buying a new pump I'd pull apart the old one and inspect the pumping assembly.

On 2015-05-19 by Tom

I have a gould 1hp vertical jet pump. well is 53' deep. the pump keeps running and only makes about 40psi pressure, not enough to turn the pump off. If i cut the power and try a couple days later it still holds the prime and will pump water but it wont go above about 40psi.

I checked my pressure tank, pressure is fine. I have plenty of water since i am able to run the water at low pressure. I know it has to be either the pump, or the foot valve/jet assembly in the well. that assembly costs about $250. a new gould 1hp pump 500-900 depending where i get it.

Any one's thoughts or which it most likely is? Im thinking the jet might be clogged? or something is worn out on the jet assembly, even thou i dont loose prime

On 2015-05-09 by (mod) - details of priming a 2 line jet pump

Stan that approach will not be likely to work. On a 2 line jet pump the smaller diameter pipe sends water from the pump down the well and through a venturi. The force of water being *pumped* with force through the venturi forces a greater volume of water back up the larger return line. You'd never achieve that by pouring water into the down pipe.

Search InspectApedia for or see WATER PUMP PRIMING PROCEDURE to see several alternatives that can work for you.

On 2015-04-27 by (mod) - locate the pipes coming out of the well

Thanks so much Alex - that clarifies it.

Yes you could rotate the cap but first I'd try removing, re-pipe-doping, then reinstalling the elbow so that you can route that line around the vertical one.

About the pump company's technical service rep not knowing what a union is, that's not only disappointing, it shakes your confidence in whatever advice she or he may offer about any plumbing or pump topic. If that happens to me I ask if there is someone else there with whom I can speak and who actually knows something. It's smart to remain polite and patient but sometimes a reply is just too much baloney.

The rep's reference to heating pipe almost certainly refers to black ABS well piping. The fitting is screwed to the pump mount opening, the pipe is heated with a propane torch, and pushed onto the pipe fitting female end. It's further secured (when cool) with one or two stainless hose clamps. That connection indeed needs less lateral clearance than steel or brass fittings.

Alex: please see our discussion in the article above.

On 2015-04-27 by Alex

Absolutely, feel free to post the photo...the more eyes on this the merrier.

Do you think I'll be able to rotate the pipes actually coming out of the well, versus changing the location of the pump? In my previous comment, I was actually referring to twisting/rotating the cap of the well (not the volute of the pump) so that the discharge line is closer to the pump and the suction line is farther away.

If I'm able to do this, I can keep the pump in it's current location. But I do like your suggestion of just moving the pump. In reality I do have the option of moving the pump to where the pressure tank currently is.

Another thing I find odd is that the holes on the new pump are so close together. It looks like there wouldn't be space for hard plumbing it with true unions (like the current pump has). The manual does not reference unions in their "typical installation" diagrams and does not reference the type of pipe to use.

I called their customer service (888-956-0000) and asked about this and the rep didn't even know what a union was. I asked if it was acceptable to use Polyethylene pipe with barbed fittings and she said people typically just heat PVC pipe and attach it to barbed fittings and use hose clamps.

This does not sound right to me. I've never heard of using hose clamps on PVC. Even flex PVC is intended to be used (glued) with standard PVC fittings, not hose clamps. However, I'm thinking about using Polyethylene pipe with barbed fittings and making a cover to protect the pipe from UV rays. Any thoughts on going this route?

Reply:

Joe, you could try inserting bleach into the pump priming chamber, but it would be a repeated process, tedious, and messy. The best approach is to open the well casing top, measure the size of the static head of the well (how much water is in the well when it is at rest) and then put the proper concentration of bleach directly into the well.

By following that procedure you'll also have an opportunity to wash down the well casing interior - a step that may make a big difference in clearing up your bacteria problem.

Search InspectAPedia for "Well shocking procedure" for details on how to do this or see

WELL CHLORINATION SHOCKING PROCEDURE

Clint, shocking a well won't fix a low yield problem. For complete instructions on how to shock a well, search InspectAPedia for "Well Chlorination Procedure: when and how to shock a drinking water well " using the "Ask a Question or Search InspectAPedia" box found just above.

Don,

A plumber may be able to rig up a bleach feed onto the down-line into your 2-line jet pump well, but without access to thte well head you may have no idea of how much static head of water is in the well so the bleach quantity will be either a wild guess, or you'll send bleach down until you smell bleach coming out of a nearby faucet. Don't buy odorless bleach or that aid won't work.

A plumber with pipe locating equipment might be able to find the well head for you - which would be worth locating and then making a car/truck safe access cover to it.

Question: how to find the well to check the foot valve

(Mar 24, 2014) Ted said:

how do i know if my foot valve is bad on a two line system. and how do i find the well opening.

Reply:

Ted,

How to Find a Water Well:

If your system keeps losing prime that's a good clue that there may be a bad foot valve (or a leak in well piping).

I can't know where your well is located, but there are some common approaches starting by noticing where well piping exits the building, inspecting the site for places we would NOT put a well (like near a septic field), contacting well drillers to ask who drilled the well (often they have records of its location), inspecting the site for obvious clues (depressions, well casing visible above ground), and ultimately, using equipment to follow well piping.

At CHOOSE WELL LOCATION & DIGGING METHOD we discuss where you want to locate a water well

At inspectapedia.com/septic/Septic_Tank_Find.php we discuss how to find the septic tank - but similar methods might be used to locate a well whose casing or top is buried and not immediately obvious.

If inspecting the property itself does not disclose an above-ground, visible well casing and cap then you may have an older well whose casing top was left buried.

I'd start by looking in the building for a sketch of well location - often left in a basement or crawl area over or close to the pressure tank and pump/controls, or sometimes even sketched on a ceiling joist or wall where the well pipe exits the building.

If that doesn't come up with a sketch of well location, continue by calling all of the well drillers in your area to ask if one of them installed the well.

Well piping can often be traced using pipe locating equipment.

A last resort is a series of small test excavations to follow the well line.

The pump can't maintain prime. I am guessing it's a bad foot valve.

How-to get at the foot valve:

this is indeed a bear.

To access the foot valve you will have to remove the well pump and piping from the well cap at the top of the casing, then either get those bolts out or cut or break them in the process.

Which should not be the end of the world in that you can replace the well casing top seal and will want to anyway. you're probably looking at a compression-type well casing top seal: two metal plates squash together squeezing a rubber center that expands to seal around pipes and well casing.

Relieving the tension unsquashes and lets you pry out the remaining parts.

Beware to avoid dropping stuff down into the well. Perhaps if just one bolt is loosened you will be able to loosen the cap seal.

No I don't see a check valve. I see ABS plastic well piping.

Watch out: A well driller would use one or more special grabbing tools to be darn sure not to drop the whole shebang down into the well in the course of trying to get the cap off.

If you insist on doing it yourself, after you've dropped the pipe into the well, you can read about well pipe & tool retrieval tools here at InspectApedia, taking comfort in the fact that many dopes were way ahead of you in dropping stuff down the well. (Including me).

(Apr 9, 2014) Anonymous said:

Those bolts wouldn't move a millimeter. I have tried wd-40 and a big wrench. Would it be possible to remove the clamps on the black ABS pipes and try to pull the pipes up? Do these ABS pipes extend all the way to the bottom?

Reply:

You can try but I'm doubtful, unless you can use a hoist connected to the well casing top to force-pull the whole top out of the well.

Typically the ABS well piping extends to the foot valve that is the water pick-up point, itself some feet off the very bottom of the well. But the well piping may be interrupted and joined by couplings or unions where it passes through the well casing top.

Question stuck in injector on 2 line jet pump well systems

(May 28, 2014) Tracey said:

In the course of business, we run across these 2-pipe injector systems quite often. They are usually in water wells with 4" casings and the injector (being nearly as large as the casing) becomes corroded to the point that it becomes almost impossible to pull the lines out to get to the foot valve.

Are there any products that you know of that will eat away at the corrosion so the injector can be free'd in order to pull it up? I have heard of people using sulfuric acid, but I wasn't sure about that idea.

Tracey,

Indeed you've hit on a common and tough problem for which there is an industry of extraction tools to pull stuff out of wells.

I have 175 ft borewell.

Reply:

Suraj

This is an interesting question, since the pickup of water in your well didn't extend into the small 1.5" casing - I'm unclear what benefit it ever offered to you.

A problem I see is that the lift capacity of a tailpiece/venturi is limited - so only if you can fit the tailpiece and piping down in that smaler diameter will it work. That is, just extending a single line feeding water up to a higher-up tailpiece is unlikely to work.

Reply:

creeping up pressure might be a sticking gauge or there may be a pinhole leak in the bladder of a pressure tank that uses an internal bladder to keep water and air separate.

I suppose a pressure control malfunction might also be responsible but in my experience if no one was messing with the control a more likely control problem would be due to debris clogging of the control's sensor port - preventing it from properly sensing and responding to water pressure.

Let us know what you find Dinesh as that will help other readers.

Will the 1/2 hp kit work or do I need to find one for a 3/4 hp pump - my store doesn't have it in stock.

Reply:

Lou,

The size of the injector is essentially matched to the flow rate produced by the jet pump. Naturally one should use the injector kit suggested by the pump manfacturer.

But having a pump that is more powerful than needed should not result in lost prime. It is more likely that you have a leak in the piping somewhere between the pump and the bottom of the well or a defective foot valve.
