What to do if my Lancaster Water Filtration System is leaking water?

  If your Lancaster Water Filtration System is leaking water, several factors could be the cause. First, examine the o-ring seal on the gland nut for any damage; ensure it is correctly placed, clean, and moistened before reinstalling. If the issue persists, consider replacing the o-ring. Condensation on the reactor chamber due to high humidity and cold water may also cause leaks, so it's important to manage the humidity in the system's location. Check the inlet/outlet port connections, and reseal them with Teflon® tape if they are misaligned or cross-threaded. Finally, water hammer causing pressure spikes can lead to leaks, so installing a water hammer arrestor in the plumbing system might be necessary.

How to fix pressure drop in Lancaster Water Filtration Systems?
- K

  If your Lancaster Water Filtration System experiences a pressure drop, it could be due to a clogged sediment pre-filter. Replace the filter cartridge with an appropriate 5-micron cartridge. Also, check your source water supply for fluctuations in pressure. Note that a flow regulator (if installed) can also cause a pressure drop when approaching full flow.

Why is the water from my Lancaster Water Filtration System heated?
- D
  Derek CampbellAug 20, 2025
  If your Lancaster Water Filtration System is producing heated product water, it's likely due to infrequent use, which causes water to sit in the UV chamber and heat up. To resolve this, simply run the water until it returns to ambient temperature.

  If the lamp failure alarm is on for a new lamp in your Lancaster Water Filtration System, first, check the connection between the lamp and the connector. Disconnect and reconnect the lamp, ensuring a tight fit. If the problem persists, moisture buildup in the connector may be preventing a solid connection. Eliminate any chance of moisture reaching the connector or lamp pins.

What to do if my Lancaster Water Filtration System shows high bacteria counts?
- B
  Brenda BurtonAug 27, 2025
  If your Lancaster Water Filtration System shows high bacteria counts, several factors could be responsible. The quartz sleeve might be stained or dirty, so clean it with a scale cleaner and address the source of the staining. A change in feed water quality could be the reason, so have the source water tested to ensure it's within allowable limits. Contamination in water lines after the UV system is another possibility, so shock the effluent water stream with chlorine (bleach) before it leaves the UV system. Finally, sediment breakthrough through the pre-filter may be occurring, so have the source water tested for turbidity and consider stepped filtration.

Why does my Lancaster Water Filtration System keep shutting down?
- W
  walterjasonAug 31, 2025
  If your Lancaster Water Filtration System is shutting down intermittently, the issue might be an interrupted power supply. Ensure the system is installed on its own circuit, as other equipment may be drawing power. The UV system should not be on a circuit with a light switch.
