If you want your property's water systems done right, you need to call Drew Reinstein and KYWB. Drew handled a full scope for us—installing and refining a water filtration system, a grey water system, and setting up our water testing and maintenance. His level of knowledge and thoroughness is unmatched in the region. Absolute professional and I give him my highest recommendation.

Drew and his team worked with us to come up with the best solution for our water filtration maintenance needs, given that we have a commercial and a residential system onsite to service the 3 buildings for our guests.

Once we agreed on the best plan, they were able to source, replace and test the water system within four days between check-ins, making it a smooth process and giving our guests confidence to enjoy their stay.

Drew and the team at Know Your Water Baja (KYWB) were lifesavers for us!

When it was clear the purification system we had installed by someone else in our new Cerritos home was not done correctly, KYWB reconfigured our system so that we could have clean water, good water pressure, and no burst pipes!

They are experts at what they do and are punctual, tidy, and easy to work with. We also used them for water quality testing and feel so much better knowing that our water is safe to drink. I wish we had simply hired them from the get-go. If you want a quality system that works the first time around, I highly recommend them!

Thank you for everything, KYWB!

We already had a water filtration system in place, but our water didn’t taste good.

I contacted Drew so he could come out and test our water. The results we got and his filter recommendations made our water taste fantastic.  We have eliminated the need for garrafons of water. No more heavy lifting!

His service was knowledgeable, friendly, fast, efficient and easy.

I wanted to share a really good experience I just had with a home upgrade. My house came with a standard hydropneumatic system, but lately, the pump was constantly cycling and my water pressure was struggling.  It took forever to get hot water to the showers. 

I luckily ran into Drew, who's a surfer and a friend here local in Pescadero. He tested my water and designed a pump and filtration system that completely changed things. I usually get a ton of anxiety when people work on my house, Drew and Paco were total pros.  He did exactly what he promised and right on schedule.

​Now, the system is quieter and more efficient, and we have clean drinking water right from the tap!

If anyone wants his contact I'll happily pass it along and recommend him to anyone.

I thought something might have been amiss with my water filtration system because of how I was feeling.

Drew tested the water and shared the results that proved I was right to be concerned. He also worked with me on a filter replacement plan that worked for my budget and timing.

Being able to talk directly with him about my concerns, my options and know that he is helping to manage my maintenance takes such a weight off of me!
