Filtered water at every tap, from one filter at the main.

Grit in the aerators, a chlorine taste in the glass, orange stains in the sink. A filter at the main line treats the water before it reaches the fixtures, and an under-sink filter handles the drinking tap. Royal Flush Affordable Plumbing mounts the housing, fits the shutoffs and a bypass, and runs the pipe so the flow stays strong.

Signs you need this

Six reasons homeowners add a filter.

A filter treats what the water carries, so the symptom tells you which kind. These are the ones we hear most.

Grit or sand in the water

Fine particles in the supply collect in aerators, showerheads, washing machine screens and the bottom of the water heater.

Cloudy or discolored water

A cloudy glass that clears from the bottom up, or brown and orange water after work on the main, points to sediment in the line.

A chlorine taste or smell

A carbon filter reduces the taste and smell, either at the main for the whole house or at the kitchen tap for drinking water.

Orange or brown stains in sinks and tubs

Staining at the drain and fixtures means something in the water is leaving a mark. We recommend the filter that suits what you see.

Aerators and appliance screens that keep clogging

The small screens in faucets and in washing machines and dishwashers catch grit first, and need cleaning more often than they should.

New plumbing or a repaired main

After a repipe, a main line repair or street work, debris in the line is common. A filter at the main protects what is downstream.

The installation decides the result

A filter is only as good as its installation and its next cartridge.

The housing goes on the main line after the shutoff and before the water heater, so everything downstream is treated. It needs a shutoff on each side so the cartridge can be changed without draining the house, a bypass if you want one, and room underneath to unscrew the canister. The photo shows the layout: copper pipe, a housing at a comfortable height and a clean run to the heater.

We choose the filter type for what the water is doing, not for the highest price: a sediment filter for grit and cloudiness, a carbon filter for taste and smell, or both in a series. We tell you what cartridge to buy and when to change it, because a clogged cartridge costs you pressure.

  • Shutoffs on both sidesThe cartridge can be changed without draining the house.
  • Pipe sized for the flowThe housing and fittings are chosen so the whole house keeps its pressure.

How we fix it

A filter install, start to finish.

A filter at an accessible main line is a single visit.

Not sure which filter you need?

Tell us what the water does: grit, cloudiness, taste, smell or staining. We recommend sediment, carbon or both. If you are on city water, the utility water quality report is also worth a look.

  1. 1
    Step 1

    We choose the type and the spot

    Sediment, carbon or a pair, on the main or at the drinking tap. We pick a spot with room to change the cartridge.

  2. 2
    Step 2

    We shut off, cut in and connect

    Isolation valves go in either side, the housing is mounted and piped in, and a bypass is added when you want one.

  3. 3
    Step 3

    We flush and check for leaks

    The system is flushed to clear new cartridge fines, every connection is checked, and the pressure is confirmed.

  4. 4
    Step 4

    We show you the cartridge change

    You are shown the shutoffs and how to change the cartridge, and what to buy for the next one.

What affects the price

What moves the price of a filter install.

We price the installation after we see the line, and you approve it before work starts. The filter and cartridges are separate.

Where it goes

A filter beside an exposed main is a short job. A run across a garage or inside a finished wall is longer.

Pipe material at the connection

Copper, PEX and CPVC use different fittings and tools.

One housing or several

A single sediment filter is simpler than a sediment and carbon pair, or a filter added to an existing system.

A drinking-water tap

An under-sink filter with its own faucet needs a hole in the sink or counter and a supply connection.

Access and clearance

Space to unscrew the canister underneath the housing decides where the filter can go.

Ask a plumber: 281-612-1015
01What is the difference between a sediment filter and a carbon filter?
A sediment filter catches particles such as grit, sand and rust flakes. A carbon filter reduces the taste and smell of chlorine. Many homes use one of each in a series at the main.
02Will a whole-house filter reduce my water pressure?
A clean filter of the right size on correctly sized pipe should not make a noticeable difference. A clogged cartridge or an undersized housing will. We size the filter for the flow and tell you when to change the cartridge.
03How often do I change the cartridge?
It depends on how much sediment is in your water and how much your household uses. A drop in flow at the taps is the sign, and the cartridge label gives the maker recommendation. We tell you what to expect for your home.
04Does a filter take the hard water minerals out?
No. Hardness is handled by a water softener, which is a different piece of equipment. A filter handles sediment, taste and smell. See our water softener page, or ask us when you call which one you need.
05Do you install under-sink drinking water filters?
Yes. We mount the filter under the sink, connect the supply and fit the faucet or connect to yours as the model allows, and check it for leaks. We can do it on the same visit as a main-line filter.
