Pitless Adapter Leaking: Causes & Solutions

A pitless adapter is important for any well. It prevents the water from the ground level from freezing on the way up. Any leaks in your pitless adapter can be dangerous. 

Problems in pitless adapters can be pretty subtle, so people often tend to overlook them. It’s important to fix this problem or things could get worse. 

How to deal with a pitless adapter leaking? 

If your pitless adapter is leaking, get a repair or replacement as soon as possible. You need a well driller to bring out your adapter from underground. Then fix the holes if possible. Otherwise, you’d need a replacement.

In this article, we’re going to discuss everything you need to know about pitless adapters. And how to deal with their problems!

How do Pitless Adapters Work?

Pitless adapters were a sort of groundbreaking innovation in the world of pumping. In the past, wells were made in large pits dug below the ground. These prevented the pipes from freezing, but this was risky for the children and animals around. 

Pitless adapters helped save these problems to a great extent. Not only did they prevent accidents, but they’d also make you aware of problems in your pump. 

A pitless adapter is a special fitting that needs to be attached to the water well casing. Which is about 6-7 feet below ground level. Buried below the frost line, it prevents freezing and discharges water through a buried water service pipe. 

Their mechanism is a bit complex, but they help in building pressure fast and robust water supply.

How to Know If You Have a Pitless Adapter Leaking?

Your pitless adapter remains deep underground, so finding out any problems within it is a bit complicated. There are a few signs that you can look into for identifying problems.

Loss of Pressure 

If your pitless adapter has any leaks in it, it will lose pressure. If your pump abruptly loses pressure after turning on, it’s due to your pitless adapter. 

You need to know about water pressure regulator troubleshooting to understand this better. This could also happen due to leaks in other parts. Make sure you check thoroughly.

If you think your pressure loss is due to your pitless adapter leaking, remove the well cap. And see if you can hear any sounds of water flowing. If you hear any sound, it’s due to the leak in your adapter.

Pump Keeps Cycling

Your pump should have a fixed time for each cycle, and it should be consistent. For example, if your pump has a cycle every 20 minutes, it should remain consistent.

Check if your pump’s cycling time is reduced. This could happen because the water keeps going out of your system. Also, if the pump keeps cycling, it will make your leak even worse.

Like the lack of pressure, you need to remove your well head cap in this case. Afterward, look for leaks. If there are any leaks, it’s due to your pitless adapter. 

How to Deal With a Pitless Adapter Leaking? 

If you have a leaking pitless adapter, you need to deal with it very carefully. There’s a fair bit of tinkering involved, so we recommend consulting a professional.

To begin with, you need to remove the pitless adapter from below the ground level. It’s important that you’re sure your pitless adapter is leaking before you start taking steps. Fill up your tank until the removed pitless adapter and check its condition. 

If the water doesn’t leak out of the pump, the problem is on your pitless adapter. 

Afterward, notice the condition of the leak. If the leaks are small, they can be filled with adhesive. If they’re too big, you need to replace your adapter. 

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.
