Filter/Pressure Regulator

New

DIG’s D54 two-in-one Filter/Pressure Regulator assembly combines a 155 mesh stainless steel filter with a 25 PSI pressure regulator, reducing the number of components needed to start a drip irrigation installation, making it smaller, more dependable and easier to install. The heavy duty filter/pressure regulator’s compact design fits in smaller sized areas while supporting reliable operation and easy maintenance of a drip irrigation zone.

Features

  • Combination of two units in one helps make installation easier and faster
  • All-purpose screen filter with built in 25 PSI pressure regulator for use in drip irrigation or micro sprinkler systems
  • Reduces incoming water pressure to the ideal working pressure for a drip system
  • 155 mesh stainless screen has excellent resistance to most common chemicals
  • Easy maintenance - the screen can be removed from the filter for easy cleaning

Filter/Pressure Regulator

About

The two-in-one Filter/Pressure Regulator is a critical part of drip irrigation systems where clean water and proper operating pressure are recommended. The cause of most drip irrigation system failures is either high pressure or clogged drip emitters; therefore, a screen filter and a pressure regulator are the most important components in the micro irrigation system. This Filter/Pressure Regulator provides the user with a single unit to both keep the water clean and lower the pressure to 25 PSI.

The screen filter is a simple and economical device for protecting a drip irrigation system from clogging. Periodically, the filter screen needs to be cleaned by opening the filter cover, removing the screen and rinsing the screen under water.

The built in preset pressure regulator is used to reduce and regulate the incoming pressure of the household’s water entering a drip irrigation or micro sprinkler system to the appropriate operating pressure range of 25 PSI, which is within the range of recommended operating pressures for a micro irrigation system.

Installation suggestions

The starting point of connection to the water supply can be an AC valve or anti-siphon valve

Installation into in-line valve, or into pipe thread

  1. If installation is into a PVC pipe, first shut off the main water supply.
  2. We recommend installing a 3/4” ball or gate valve before the AC or DC valve. This ball valve can be very useful as an emergency backup to turn the system off. This type of arrangement is used by professional installers.
  3. Turn the water supply on to flush the line and then shut the water supply off using the new ball valve or gate valve.
  4. Install an AC valve or battery operated controller, wrapping TEFLON tape on all the male thread fittings used.
  5. Turn the water supply on again to pressurize the system. The unit will open momentarily and then will shut off.
  6. To the outlet of the valve, install the 3/4” two-in-one Filter/Pressure Regulator (model D54) to protect the drip system from clogging and to lower the incoming system pressure to the suggested operating pressure of 25 PSI. Follow with a swivel adapter to the drip tubing or 3/4” PVC female threaded x slip adapter to the PVC pipe.
  7. Test the valve using the manual bleed. Check that the system is working and that there are no leaks.
