Well piping pitless adapters: This article defines the pitless adapter and explains the use of the pitless hook up pitless adapter on drilled wells that use a steel well casing, modern drinking water wells.

The pitless adapter hook up pitless adapter passage of well piping out through the side of a well casing at a point underground and without leaks where the pipe passes through the round well casing side. Well piping pitless adapters eliminate the need for a well pit to protect pipes from freezing. The pitless adapter also permits pulling out of well piping, foot valves, and submersible pumps directly through the top of the well casing.

Our page top photo shows a not-very-deep installation of a pitless adapter during parts replacement. We also provide an for this topic, or you can try the page top or bottom as a quick way to find information you need. Pitless Adapter for Drilled Wells The water pipe leaving this well to carry water to the building will be hook up pitless adapter below ground, and in freezing climates, below the frost line.

A special fitting, the "pitless adapter" is used to seal the passage cut into the round well casing to permit the water piping to pass through the casing and out to the building it serves. Similar pitless adapter fittings accomodate other well casing and piping designs.

Other clamp type fittings used at the top of a well casing may be used to seal the well top around piping that exits at the top rather than the side of the well casing. This approach is suitable only in non-freezing climates or where the well head is protected from freezing by its hook up pitless adapter such as in a well pit or inside of a heated structure.

One of our readers was having trouble pulling the pump and piping up out of their well - the pump jammed in the casing near the top of the well. We wondered if the hook up pitless adapter was unable to pass by the pitless adapter since this fitting intrudes into the well casing. Most modern drilled wells for residential properties use a 6" steel casing which is inserted into the drilled hole prepared by the well driller and hook up pitless adapter sealed at top and bottom against contamination by surface water or surface runoff.

The best way to locate a well and well casing to avoid surface water contamination is shown in this illustration. You can figure on about 1. Except in certain artesian walls the water column does not extend from the well bottom to the top of the ground. Key to our sketch of the parts and features a drilled water well In my ugly well parts sketch shown above I've marked the pitless adapter location showing where the well piping leaves the well casing through the casing side.

What's cool about most pitless adapters used on water wells is that inside the well casing the component of the pitless adapter that attaches to the top of the well piping is designed to simply slide up and out of the remaining pitless adapter parts bolted and sealed to the casing side. This feature is what allows us to pull the well piping and submersible pump or foot valve completely out of the well without having to dig up and expose and disassemble the pitless adapter from outside the well.

Our photo above-left shows the mating face of a pitless adapter just after the well driller pulled the well piping and pitless adapter slip fitting up out of an existing well. This well installation was in Two Harbors, Minnesota where the freeze depth can be so severe that many installers put the pitless adapter eight feet below the ground surface to be sure it and the exiting well piping are below the frost line.

This pitless adapter was not leaking, but this is a place we'd check for leaks if we were hook up pitless adapter for a leak in well piping. See Well Casing Top Clamp Fittings Seal Around Well Piping, Wiring, Vents Other clamp type fittings used at the top of a well casing may be used to seal the well top around piping that exits at the top rather than the side of the well casing.

This approach is suitable only in non-freezing climates or where the well head is protected from freezing by its location such as in a well pit or inside of a heated structure. Our photo above shows a top-sealed well casing that is designed to permit a single well pipe and some wiring to pass out of the top of the well casing.

This well was located indoors in a New York home - not a great idea - in the building basement. From what we see, a single water pipe exiting the well and wiring entering the well, we expect to find a submersible well pump installed here. Our second photo above shows how a compression type well casing top seal works: bolts tightened through the outside top of the seal compress a rubber gasket between two steel plates.

The expanding rubber gasket seals around pipes, wiring conduit, or whatever fittings were designed to pass through this well cap. This well casing top was installed in Two Harbors MN. Below we illustrate a conventional sealing well casing top cap used where only electrical conduit must enter the well casing above ground. At this well the water pipe exits below ground using a pitless adapter. If that leaves you with any questions please don't hesitate to ask.

On 2020-11-26 by Donald L Sayre how to install a pitlass adapter On 2018-08-25 - by mod - Thank you for the important and interesting point, George, I'll be sure it's kept with the article here and in our article series on galvanic corrosion of plumbing parts.

I suspect hook up pitless adapter since brass coupled to si-Brass should work without significant galvanic corrosion, that water chemistry in the soil or in the well was a factor.

Let us know what you find. On 2018-08-23 by George Schwartze My water line out to the well casing became leaky to the extent that water continuously flooded the area near the casing. After digging down past the pittless adapter a leak was revealed at the junction of the brass nipple to the coupling going into the pitless. Corrosion was clear on the brass pipe fitting but not the coupling.

I took a look on hook up pitless adapter galvanic chart to consider what the effect might be on brass pipe fittingsilicon brass coupling and iron well casing.

It appeared to me clear that the brass pipe was lower that the silicon brass on the corrosion chart and was therefore going to give itself up to corrosion to hook up pitless adapter the silicon brass. I think that the thing to be learned here is to be sure to use silicon brass in all parts between the plastic pipe and the well casing. Otherwise the problem is likely to repeat itself.

On 2018-02-06 - by mod - Other than the obvious difference in materials I would not expect a plastic pitless adapter to be used with iron or metal well piping On 2018-02-04 by salli is hook up pitless adapter a diifference between a steel and plastic casing pitlis On 2017-12-30 - by mod - Most likely your pitles adapter is not below the frost line On 2017-12-29 by Dan ONeil My well line freezes at the pitless adapter everytime it gets 0 or below.

I pour a gallon of warm water down the well to thaw it out and it works fine until the next night. If I put a heat tape on a piece of pipe and let it down to the pitless it wont freeze. Is there a reason this is happening, no one else I know has this problem, is there something I can do permanently to fix the problem. No if your well pipe exits the casing at a casing top that is above ground. On 2017-12-12 2 by CM do i need a pitless adapter for a well is in a non freeze zone? Reader Question: how do I protect the well water piping in the well from freezing?

When draining the water from a dwelling that is allowed to freeze, how does the water supply from the submersible pump, supplied with foot valve, drain so the at or above grade pipes don't freeze and break?

The well piping too, should be buried below the frost line. If well piping is too shallow, indeed it may freeze up in very cold weather. Water piping exiting older wells in some areas were protected from freezing by constructing a well pit that kept the well head far enough below the ground hook up pitless adapter to avoid freeze-ups.

But well pits hook up pitless adapter still permit a freeze-up in prolonged and very cold weather. Sometimes a simple light bulb is enough. More tips about protecting a building from freeze damage are organized at.

Question: what's the best tool for cutting the well-casing hole for a pitless adapter? Apr 28, 2016 George said: What happens to the metal filings when the hole is drilled for the pitless adapter? What is the best hole saw to use for drilling a hole for a pitless adapter? Reply: George: A bit of metal debris probably falls into the well when the pitless adapter hole is cut using a metal hole saw or a welding torch. Provided the pump is several feet or more above well bottom as is normal to avoid sucking up mud and dirtthat debris ought to be harmless.

In a freezing climate that needs to be below the frost line. For a two-hole pitless adapter used with 2-line jet pumps you'll need to inscribe a vertical line down the casing and to measure the proper distance between two center punches so that the two drilled holes hook up pitless adapter be located correctly to fit the two-hole pitless adapter. Naturally you'll use a hole saw with teeth and metallurgy designed for metal drilling. Use a hole saw that includes a pilot bit that centers on that punch you used as we describe above.

The manufacturer of your hook up pitless adapter adapter will provide a table of well casing hole size diameters required for each model of pitless adapter. Hook up pitless adapter "pull pipe" is attached to the top of the in-casing side of the pitless adapter and is used to lower the assembly into the well. Basically the male and female parts of the new pitless adapter are installed atop the drop pipe that will be lowered into the well.

For a submersible pump the pump is attached to the bottom of the drop pipe. For a 2-line jet pump the hook up pitless adapter well pipes and foot valve are attached to hook up pitless adapter pair of drop pipes. A "female" o-ring seals the face of the in-casing female adapter to the interior side of the well casing and the nose of the female adapter is pushed out through the hole you drilled in the casing.

Outside the well casing a gasket, back plate and finally lock nut are installed onto the pitless adapter so that it can be connected to pipe s connecting the well piping to the building it serves. Continue reading at or select a topic from the closely-related articles below, or see the complete.

What is the purpose of a pitless adapter?

Later known as the pitless adapter, Martinson’s basic design remains in use to this day. Original patent for the pitless adapter. Thanks Milton! The primary function of the pitless adapter is to provide a junction for the drop pipe in the well to connect to the water line running to the house.

Why is my pitless adapter not working?

Sometimes, your pitless adapter might have a lot of sediments due to the minerals in your water. This will obstruct the flow of water. You need to clean it thoroughly with a cleaning solution before reattaching it. If you wonder what’s the best solution for cleaning your adapters, here’s our recommendation:

What is a pitless water drop pipe adapter?

The primary function of the pitless adapter is to provide a junction for the drop pipe in the well to connect to the water line running to the house. As you can see from Martinson’s original patent diagram, the main modification with the pitless adapter is that the drop pipe exits through the side of the casing rather than through the top.

How do I install the pump seating on the pitless adapter?

Remove the safety pin to allow removal of the elbow F portion of the pitless adapter out of the slide E. At this point, you can attach the pipe column, which is the drop pipe and submersible pipe, and install the pump seating to the pitless elbow into the slide of the pitless adapter.

What is a pitless pump adapter?

Single pipe slide type pitless adapters are the most common type and they are mainly used for submersible pump installations but can also be used for shallow well jet pump systems where a single suction line is lowered into the well with a foot valve attached.

How do you cut a pitless plug adapter?

Using a hole saw, cut the required hole size, as specified by the pitless adapter manufacturer, through the well casing and remove the burrs. For 1 pitless adapters, the typical hole saw size is 1-3/4. Next, you will need to remove the brass nut A, the brass washer B and the outside rubber washer C.

Who invented the pitless adapter?

He saw the flaws inherent in well pit installation, and came up with a “means for extracting the liquid from a cased well below the top of the casing” in its stead. Later known as the pitless adapter, Martinson’s basic design remains in use to this day. Original patent for the pitless adapter. Thanks Milton!
