Pond pumps. Pump maintenance

- The pump is probably the most expensive part of the pond installation so take good care of it during the winter months. The store where I purchased my oil filled pond pump and filter system recommended to remove the pump from the pond and store it during the winter in a bucket with pond water in a frost free location. This will prevent the seal and/or gasket from drying out and thereby extend the life span of the pump. Magnetic and epoxy sealed pumps can be stored dry.
In spring, reinstall the pump in your pond once all danger of freezing has passed.

Make sure to provide a ground fault circuit interrupter (GFCI) outlet near the pond. Any wiring from the power source to this outlet should run through a conduit.

Pond pumps. Pump maintenance
To maintain a healthy pond environment it is crucial the have the right size of pond pump. The pump circulates the necessary oxygen for your pond fish.
Once you know the size of your backyard pond it is time to calculate the size of the pond pump, which could be tricky. Pumps are sized by gallons per hour (GPH). Most experts agree that the water in the pond should be circulated at least once every hour. So for a 300 gallon pond you would need a pump rated at 300 GPH, that is, if you do not want a waterfall or fountain. If you want to add one of these features you will have to increase the GPH rating. It is important to know the height of the waterfall or fountain and the type of filter you will be using. The GPH increase required is not the same for all brands so if your are buying the pond pump at a retail outlet check the chart on the box or go to the manufacturers website. Better yet, go to a pond store and consult an expert.

- Finding out how much water your pond will hold is a snap. Forget about the complicated calculations listed on several websites, just follow these simple steps.
1. Record the water meter reading before filling up your pond.
2. When the pond is full take another reading of the water meter.
3. Subtract the original reading from the last one and your done!
Make sure no one uses the bathroom or takes a shower during the pond filling!

For winter storage I keep my pump in a bucket filled with pond water

- It is better to buy a pump that is over sized than under sized.
- To release pressure created when water turns into ice throw in a few swimming pool noodles and/or tennis balls before the water freezes.
