Happy Camper

I actually think that your system has made my pool maintenance much easier. Before I installed it I was constantly having to scrape the border tile to remove the calcium deposit, now I rarely have to scrub it and it seems that the calcium is deposited on the bottom of the pool and all I do is vacuum it and this has made me recommend your system to others.

Big difference in cleaning

We have had several water salt softners over the years, but had gone about six months without one when our last one broke down. It has been wonderful to get back soft water with a no hassle system. What a blessing not to have to get heavy salt bags and refill a tank. Sinks and toilets are staying cleaner longer and we are using less cleaning products.

Very Impressed with customer service

I feel that your customer service does an outstanding job answering any questions that the customer may have. I not had to deal with any problems with the product and the installation was fairly easy. Also, I no longer need to put up with getting salt, putting it into the tank and cleaning the tank out. No more beads and cycling.

It works.

We had some trepidation going in; the claims for the Pelican conditioner seemed too good to be true. But it's both good and true. The calcium deposits are a thing of the past, and without wasting tons of water on regeneration cycles or dumping tons of salt into the ecosystem. We also found your customer service rep, Matt, to be extremely courteous, knowledgeable and helpful. Kudos all around.

loving it!

We have only had our water softener for a couple of months, but already we are noticing a big difference in how our skin feels, and our detergent usage. We have well water, which was tested as very good, except for the hardness level, and they recommended the system we now have. We were impressed with their honesty, as they could have insisted we would need something more expensive. We were skeptical about the salt-less system, but after viewing their informative videos that gave info. on both types, could make a decision right for our situation. The sales man was great, not pushy, and gave us space to make a decision. All in all, we will be happy to recommend Pelican Water Systems to any one who needs great water.

No Water Spots

My new Pelican non-salt water softener has not been in for a whole week yet and I am already very impressed with it because leaves No Spots in my stainless steel kitchen sink! I had no idea that would be a perk! I am very pleased with it: No Salt! No Electricity, minimal maintenance. Great product!

Great Product

I just recomended my fourth NS3 water softener to a friend. He is so happy with this unit as all the others friends are. Could not beleive the difference in the water. I have mine for two years now and still works like the same day I installed it. I have a black car that I couldn't wash at my house because it left white spots all over. Since I installed it, I can now wash my black Corvette at home. We are four happy customers from Pelican. NICE JOB

Thumbs up for the NS6

We installed our NS6 about 60 days ago, give or take. We are on well water and had been replacing our tankless water heater about every 3 years. Our second tankless was already making grinding sounds and is not 3 yet. It started getting quieter in about 2 weeks, then grind a little but this morning and for several days it is silent. Plenty of hot water too. The wife is a faucet polisher....she stated she used CLR every 2 or three days.....she is down to every couple of weeks on the CLR treatment. She started talking positive about the softner after only two days...I have a story about my 1 quart mug that I will not tell, for brevity. My commode handle broke. When I took off the tank lid, everything below the water line was like new...the valve above the water level still had scale on it.....I CLR'd the top and now all like new..Have talked one neighbor into buying one... I continue to watch for signs that it is not working but we are getting more and more sure that it is working fine...Now; how long does it last? Thank you Patrick.

Pelican Water Filter

Having the NatureSoft NS3/NS6 has been the best investment I have ever made. Our condo association has well water. I am very pleased to know the money I am saving, not only in the preservation of my new washer, dryer, dishwasher, and shower heads, etc., but the very small amounts of detergents, soap, shampoo, etc., that is needed to clean. No more rings inside toilets, nor calcium nor other mineral deposits, anyplace. And less time having to scrub the deposits as before, leaves me with a lot more time for more important things to do.

Impeccable Service

I am very impress with the level of service and knowledge, as well as the willingness to spend time answering all my questions with such valuable information. I appreciate knowing that it is not necessary to have a plumber reinstall the carbon media which will save hundreds of dollars. Thank you once again.
