CRYSTAL QUEST® Undersink Replaceable Triple Multi PLUS Water Filter System Save 32% Off

The Crystal Quest under-sink triple filter

The pros are:

(1)Seems durable

(2)Fairly simple to install.

(3)Inexpensive, industry standard filters can be used.

(4)Three filter housings gives you the ability to use a variety of filters such as for removing minerals, removing fluoride, removing nitrates, etc.

The cons are:

(1) It comes with a saddle tap which punctures a copper line. This doesn''t work on stainless steel or flexible lines. Other brands come with a screw-in Tee fitting. I needed to separately buy the tee (with shutoff) from another company for $8.

(2) Not possible to know if filter is in place inside the housing.

(3)I have run 10 gallons through the system and the filtered water tastes worse than the untreated water. If it doesn''t get better I will swap out filters to see which one is the problem.

To install the spigot I had to drill through a porcelain-covered cast iron sink. While the internet is full of horror stories, this was not that difficult. I completed the hole in under 20 minutes using carbide-tipped masonry drill bits.

The Crystal Quest 8 performs very well. The water tastes great and the flow rate is very good. It mounted easily under the sink; however, the linkage on the outflow side (inflow side as well) are poor quality and leaked repeatedly until I purchased a replacement at the local hardware store for $5.00. Since that time it has performed very well with no leaks or other problems. It is frustrating that this otherwise high quality product skimped on two very inexpensive parts. However, I still strongly recommend this water filter.

We ended up ordering this direct from the manufacturer since they have the option to order it with the t-valve. Of course, I''m sure these valves can be purchased at a hardware store, but I needed the convenience of ordering the property items all at once.

Amazon should consider selling two systems (one with the t-valve and the other with the saddle valve).

I looked into many different filters before buying this one. This is easily one of the best water filters out there for the following reasons:

Pros:

+ Lowest/Very low $/gallon costs (because of low cost of unit, inexpensive filters and long filter life)

+ Simple installation (for an under the counter filter that is)

+ Filtered water tastes normal

+ Takes standard filters, so you can purchase generic filters down the road (versus only-works-with-our-system filters that do the same functionality at a higher price)

Cons:

For the water inlet, they ship a piece that clamps and punctures the copper pipe to draw water. This is fine if you have a copper tube, most folks would have regular piping, so a regular T junction should be there (or a different SKU with that part)

Tips:

The easy-snap connectors are great but if you''ve never used/seen them before it''s easy to mess them. If in doubt, test it out before the final installation. I had a leak and thought the connectors were faulty. In reality I hadn''t done the easy-snap connections properly.

Want CRYSTAL QUEST® Undersink Replaceable Triple Multi PLUS Water Filter System Discount?

We live in rural Kansas and our water is sourced from the Neosho river. It''s hard water, loaded with AG chemicals and tastes like treated water. With the Crystal Quest filter, our water has absolutely no taste at all and is clear. Flow rate from the faucet tap is very good, operates easily and looks nice.

Product quality is OK. I do have a few bitches. The T valve fitting''s threads are made in China quality. It takes a ridiculous amount of Teflon tape to get the joints to quit leaking. The faucet tap vanity plate is barely large enough, and I mean barely, to cover the factory hole in our three hole sink. The plastic washer for under the sink is the same situation. I am worried about the long term strength of this part of the filter system.

The plastic parts went together fast. Take your time with the one plastic hose insert. It needs to be lubed before pushing into the hose. There was plenty of hose to locate the unit out of the way. For a seasoned DIY guy, installation was easy, except for the T valve driving you crazy.

Over the long term, this filter should cost us less to operate than our old PUR filter.
