Frequently Asked Questions:
How do you install the Pentair DGD-2501-20?
- Prepare a a bucket with clean soapy water ahead of time because once you open the filter housing, you probably won't have access to water until you're finished.
- Turn your water supply off. You probably have a shutoff on the supply line located before the filter. If not, go to the hydro panel and turn the pump off.
- Relieve the water pressure on the lines before you unscrew the housing that holds the DGD-2501-20 water filter. You can turn a faucet on inside the house to relieve pressure and let the water run until it stops. Then, shut off the water after the filter housing to keep the water from the house from draining back.
- Place a bucket under the filter housing. If the housing has a relief button push that to make sure all the pressure is gone. Unscrew the housing and take it off.
- Remove the old DGD-2501-20 filter and clean the inside of the housing with soapy water and towels to remove any built-up debris. Unwrap and put the new DGD-2501-20 filter in the housing and screw the housing back in place, slightly more than hand tight.
- Turn the faucet off that you had running to relieve pressure. Turn the main water supply back on, slowly. Check for leaks around the cartridge housing.
- Flush the new DGD-2501-20 filter with at least 3 or 4 gallons of water or until the water flowing after the filter is clear.
How often should you replace the Pentair DGD-2501-20?
Changing your Pentair DGD-2501-20 is a very quick and easy process that should be done once every three to six months.
What contaminants does the Pentair DGD-2501-20 reduce?
The Pentair DGD-2501-20 is NSF 42 certified, which means that it reduces the following contaminants:
- Chlorine Taste and Odor Reduction
Can the Pentair DGD-2501-20 be used as a standalone filter?
Yes. Its dual-gradient design combines pre- and post-filtration into one cartridge, potentially eliminating the need for separate step-down sediment filters.
Will the Pentair DGD-2501-20 reduce water pressure when it starts collecting sediment?
As sediment accumulates, flow can decrease, so reduced water pressure can be an indication that the cartridge needs replacement.
Does the Pentair DGD-2501-20 need to be flushed before use?
Yes. Flush at least 3–4 gallons, or until the water runs clear, after installation.
