• All of our pond liners are safe for fish, plants and all other aquatic life. Roofing liner are not safe for aquatic life be sure your liner is a pondliner.
|
| What is EPDM Pond Liner? |
|
• EPDM (Etylene Propylene Diene Monomer) is a synthetic rubber pond liner. It is flexible, puncture resistant and offers excellent UV stability. It is easily seamed and patched. |
| What is Polyethylene Pond Liner? |
| • Polyethylene is a plastic type material that offers good UV resistance. It is stiffer than EPDM. It is more affordable and lighter than EPDM. It can be manufactured in many different sizes. |
| Can I order a liner in any dimension I want? |
| • The EPDM pond liners must be ordered in dimensions divisible by 5. All sizes are listed on our EPDM pond liner link. Polyethylene liners may be ordered in ay dimension. We have a few common sizes listed on our site however we are able to provide any size you may need. PVC liners must have 1 side of the dimension divisible by 6. We have a few drop-in liners listed however we can have those custom made to dimensions that fit your project. |
| Can I order a liner in a particular shape? |
| • No. All liners are fabricated in a square or rectangular flat sheet. |
| How much material overlap do I need? |
| • We believe that a 2' overlap is needed for pond edging and margin of error. |
| Do I need underlayment? |
| • Yes. It is a wise decision to purchase the underlay to match your liner dimensions. It gives your liner longevity, protecting it from tree roots, rocks, rodents and soil chemicals. |
| If I want to seam two liners together, which material should I use? |
| • EPDM liners can be seamed with minimal effort. EPDM can be seamed by using the seam prep, tapes and lap sealant. The Polyethylene liners can be seamed using H50 tape in small areas or a heat device for larger areas. PVC can be seamed in small areas using PVC glue and heat welded for larger areas. |
| If I develop a leak in my liner , how do I patch it? |
| • EPDM liners can be patched with minimal effort. EPDM is easily patched using our EPDM patch and tape activator. The area should be preped with tape activator. The patch adheres to the liner, and forms a bond stronger than the original material. PVC can be patched with excess PVC material and HH66 vinyl cement. The PVC material should be cut in a circular patch and bonded to the liner using HH66 adhesive .Polyethylene liner can be patched using H50 tape. |
| What color are your liners? |
| • All of our pond liners are black. |
| What size liner do I need? |
| • First you need to measure your widest point (straight across), your longest point (straight across) and your deepest point. Depth x 2 + width + 2= Liner width. Example: Pond that has widest point of 4' with a deepest point of 2'. Double the depth to make 4' then add the width of 4' and add 2' for the overlap. You would need 10' wide liner. Repeat for length. |

| What size pump do I need for my pond? |
| • To maintain a healthy pond it is recommend to circulate your water every hour or at a minimum once every two hours. There are various factors to consider when chosing a pump. You must take in to consideration vertical lift, tubing size, filters, fittings and hose length. |
| What is head pressure? |
| • The force/resistance that the pump must overcome to push the water out at the end of the tubing. There is pressure from the vertical height to the discharge poing and there is also pressure caused by the tubing and fittings. |
| Can the pump flow be adjusted? |
| • Some smaller pumps come with a diverter valve or a flow control valve. In other pumps you will have to use a ball valve or a diverter valve in order to adjust the flow. |
| What is the difference in magnetic drive pumps and direct drive pumps? |
| • Magnetic-Drive (Mag-Drive) pumps have a motor that creates a magnetic charge to spin an impeller which creates water flow. These pumps are more energy efficient, however they don't produce as high of flow rates as direct-drive pumps. Direct-Drive pumps have a motor that directly spins a shaft which powers the impeller. |
| How much will it cost to operate my pump? |
• Use the following formula to dertermine monthly cost to operate your pump.
Watts divided by 1000 x kilowatt cost per hour x 24 hours x 30 days
Check with your power company to determine the kilowatt cost. |
| How do I determine the volume of water in my pond? |
• Use the following formula for square or rectangular shapes:
Average width x Average length x Average depth x 7.5= Gallons of water
For circular ponds:
Half the diameter x Half the diameter x 3.14 x 7.5= Gallons of water |
| |
| Do I need a filter for my pond? |
| • Maintaining a healthy pond environment with crystal clear water usually requires a filtration system. If you have a water feature with no plants or no fish, you might be able to have good water quality. |
