Basically it is a bulkhead fitting with a spring valve that will open up when the pressure is too much. In your case it sounds like you shouldn't have a problem with a liner, especially if you have sandy soil. A liner will work wonderfully in that situation. James,

It will dry up over the winter if I turn the pump off. And what is the natural water table rises? Wouldn't the greater weight of the water on top of the liner offset the rising pressure. So if you get these gas bubbles what happens if you just poke a small hole in the liner to release it? I have a big pump and well capable of filing the pond in 30 days (4 Ac.) but with the sandy soil I can only maintain a depth of about 3' then it will drain latterally though the ground. I have been considering a liner after I complete the eradication of the cattails and use muck away pellets to eat up the organic matter. OK but what if the natural water level is seasonal?

If you pond fills to the top and stays that way, then you don't have to worry about a liner at all, nor is using a liner at this point a possibility. #2. When you have 25% or more of the pond's capacity filled with water, it can be very difficult to line the pond. If you place the liner on top of the water and fill up the pond, organics are continuously decaying underneath the liner. As these organics decay, they create gases. As these gases collect, they can literally lift the liner to the surface. It will look like liner bubbles on the surface. This is why we do not suggest using a liner when the pond will hold more than 25% of its capacity on its own. We usually suggest researching bentonite or lining the sides with clay when your pond will only contain 25% or greater, as these may be the only options to allow the pond to fill with water. I have used check valve bulkheads when laying the liner to help release the gases underneath the liner, but they don't work that well on their own and usually require someone to manually release the gases. Hopefully this helps! The Pond Guy Lisa, this is a good question and I should have elaborated on it a little more in the blog.

What if it does fill with natural water by 25% or greater as you mention in the above information. We live in an area surrounded by swamp. I have not yet dug the earth for our pond.
