ProfessionalWater Filter Installation

Under-sink water filters and refrigerator line connections give you clean drinking water without the recurring cost of bottled water. We tap into the cold supply line, mount the filter housing, and run the filtered line to a dedicated faucet or your fridge — cleanly, without drilling more than necessary.

How it works

1

Plan the installation

We identify the cold supply line, choose the best mounting spot for the housing, and trace the filtered line route to the dispensing point.

2

Connect and mount

We tap the supply line, attach tubing, mount the housing, and connect the output line to the faucet or fridge fitting.

3

Prime and test

We open the supply, flush the system as directed, and check every joint for leaks before declaring the job done.

We can help

Problems we fix

  • Saddle valves that corrode and leak over time — we prefer compression fittings when possible
  • Under-sink clutter making hose routing and mounting difficult
  • Refrigerator ice makers that produce cloudy ice because the supply line was never filtered
  • Filter housings installed without enough clearance to change the cartridge easily

Good to know

Water Filter Installation — FAQ

Do I need to buy the filter system first?

Yes — filter systems vary widely in size, connection style, and filtration stages. Purchase the system you want and we'll install it to spec.

How often do I need to change the filter?

Most cartridges are rated for 6 months or a set number of gallons. Your filter system will specify — we'll note the install date so you know when to start tracking.

Can you connect a filter to my refrigerator at the same time?

Yes. If you want filtered water going to both an under-sink faucet and the fridge, we can split the line during the same visit.
