Watts WH-LD Premier Whole House Water Filter

Watts WH-LD Premier Whole House Water Filter Review

If your biggest concern is sediment and rust in your water, then you have come to the perfect place.

Keep reading this watts whole house filter review to learn more.

A conventional 2 or 3-stage whole house water filter removes chlorine, hydrogen sulfide, heavy metals, chemicals and a whole lot other contaminants in addition to sediment.

But if you are not worried about these or you already have an activated carbon whole house water filter installed, I recommend the Watts WH-LD filter.

It is a sediment-only filter. That means it only helps with water turbidity. The filter cartridge traps sediment, silt, and rust. This makes your water clearer and preventing stains from appearing on surfaces.

Read on for my full review on installation, ease of use and filtering performance of the Watts WH-LD filter.

If you are looking for a complete 2 or 3-stage system instead, see my in-depth whole-house water filter buying guide for the best recommendations.

Water Filter Performance

watts premier water filter review

Do not compare the Watts WH-LD filter to a normal whole-house water filter. They are very different.

As I mentioned, a conventional whole-house filter can remove a wide range of contaminants including chlorine, industrial chemicals, and heavy metals. It significantly enhances the taste of your water.

But the Watts WH-LD filter does just one thing – remove sediment.

But it’s very good at it.

The filter cartridge provided when you buy the filter is rated at 50 microns. It can remove really small stuff from the water, including particles you can’t see.

For context, a grain of beach sand is about 700 microns big. Fine sand is 250 microns, and cement is 74 microns.

The human hair is 70 microns big. Silt and household dust are between 40-60 microns in size.

Water coming out of the other end of this filter is going to be clear and free of almost all suspended particles.

One thing I love about this filter is that you have the option of using your own finer filters.

So if you feel that 50 microns are not fine enough for you, just buy a 20 or 10-micron filter and use it instead (the filter uses standard cartridges that you can easily find at the local hardware or plumbing store).

Just know that a smaller-micron filter will clog relatively quickly and will need to be replaced sooner.

The Watts WH-LD does not significantly change the taste or smell of water. But it makes it clearer, fresher and safer to drink.

Installation & Maintenance

watts whole house filter review

Whole house water filters are great and all, but they are a pain to install, often requiring you to spend more by hiring a plumber.

The Watts WH-LD is an exception.

Being a sediment-only filter, installation is easy and quick.

You just need to cut out a small section of your pipe, fit in the filter and you are good to go.

Start by figuring out where you want to install the filter. It should be on the main line after the water meter but before you get to the water heater or the line starts branching off.

Close the main water supply and drain the plumbing by opening several taps and letting them run out.      

Before you start, make sure that your main pipe is compatible with the ¾" ports on the filter. If your line is bigger or smaller, you'll need to buy an adapter.

Something else to note: the Watts WH-LD filter doesn't come with a mounting bracket to hold up the filter. Most customers recommend the Culligan UB-1 Mounting Bracket.

The filter comes with a wrench, so you don't need to buy that.

Once you have everything in place, go ahead and install the mounting bracket and filter. Apply food-grade lubricant on the threads before fitting the filter to avoid leaks.

Installing Multiple Filters 

If your water contains a lot of suspended particles, it's a good idea to install multiple filters.

This will improve filtering performance and extend the life of individual filters.

You can install multiple filters (order as much as you need). I recommend 3-4. 

You'll also need to buy your own filter cartridges. Get a 20-micron one, a 10-micron one and a 5-micron one (don't buy a 50-micron cartridge, because you'll get three with every WH-LD filter you order).

Arrange the filters in order of descending micron sizes: 50 microns, 20 microns, 10 microns, and 5 microns.

If the water pressure drops, feel free to use only three filters (e.g., 50, 20 and 5 microns).

Maintenance and Filter Replacement 

The filter requires almost zero maintenance. Just keep checking it for leaks.

Other than that, you just need to monitor the condition of the filter through the clear housing. You'll notice when it begins to fill up with dirt.

Replace it when it gets clogged and water pressure begins to drop.

Replacing the filter is easy.

Because the filter has a built-in bypass valve, you can keep water flowing to the house as you put in a new filter.

Once you turn the valve, unscrew the filter housing using the included wrench. Do it gently to avoid breaking the housing.

Remove the old filter cartridge, rinse the housing and put in the new filter.

Before screwing the housing back into place, apply some cooking or olive oil on the threads, so that the next time you need to replace the cartridge, they unscrew easily.

What We Like The Most About The Watts WH-LD Whole House Filter 

watts whole house filter review

The one thing that we like most about the Watts WH-LD whole house filter is its simplicity.

It's easy to install, replacing the filter cartridge is a breeze, and it requires almost no maintenance beyond filter replacements.

With this simplicity also comes a low price. Even if you decide to install 3 or 4 filters, you'll still spend way less money compared to a conventional whole-house water filter.

There's really nothing to worry or complain about, as far as the filtration performance is concerned.

Sure, it won't remove the chlorine taste from your water or kill waterborne bacteria. That's work for a complete multiple-stage filter, which is not what you are looking for anyway. 

The WH-LD does one thing only and does it well.

If your city or well water is full of sediment, silt and rust particles, this is the best filter.

What We Don't Like About This Filter

The one thing that we don’t like about this filter is that it does not include a mounting bracket. This doesn't save cost since most people end up buying one anyway.

Including a mounting bracket along with the filter would save customers a lot of hassle.

The Watts WH-LD Is Perfect For You If...

watts whole house filter review
  • You are looking for the best whole house sediment filter for city or well water.
  • You already have an activated carbon filter installed and want to add a sediment filter to the main water line.

 Avoid Buying This One If You...

  • Want to remove chlorine, chemicals and dissolved minerals from your water. This filter only removes sediment.
  • You are concerned about bacteria and viruses in your water. Again, this filter removes only sediment
  • Tip: you can still buy this filter and then buy an under-sink reverse osmosis filter for drinking water. Alternatively, buy a UV sanitizer and install it after this filter.

Our Bottom Line
