Frequently Asked Questions
- How does it work?
Using a patented, multi-state process of filtration, air injection, and UV disinfection, the NEXtreater is able to de-soap your drainwater to NSF350 standards. This allows you to reuse the water in traditional irrigation systems (such as spray irrgation) and even for toilet flushing.
- Who will install it?
Retrofit installations are typically done by a contractor in our network or one selected by the homeowner. For new homes installers are usually the general contractors or home builders. We of course provide whatever (often off-site) assistance we can to all state licensed contractors.
- Who provides the plans and permits?
Typically the general contractor or equivalent, although we have many resources to assist them in this task.
- Earlier you said something about NSF350 treated grey water. What's that? How does that differ from other available products?
- Who provides the maintenance?
We provide servicing for the period agreed in the terms of sale – generally, 2, 5 or 10 years.
- What degree of maintenance does the system require?
The maintenance for the NEXtreater is pretty straight forward, with the only consumables being a pleated filter, a UV bulb, and 60 pounds of carbon. The carbon will need to be replaced approximately every 5 years and the UV bulb and pleated filter will likely need to be changed at least once a year.
- What is the service and warranty plan like?
A 2 or 5-year service plan is included with your NEXtreater, but extended warranties and service agreements are available that will provide you with up to ten years of full protection. We monitor your system performance remotely, so there is little need to for homeowner interaction. If there is a ever a problem, we will tell you!
- When precisely does warranty commence?
The warranty period starts when the treatment appliance (the NEXtreater) is delivered, installed and turned on for the first time.
- How easy is the installation process?
In short, the installation process is easier than ever. With our "Recycle Ready Assembly" the underground infrastructure arrives fully configured, palletized and ready to go, so your contractor is only responsible for 5 easy connections.
- What support does the seller, Nexus eWater, provide?
We work remotely with the builder/certified contractor to, most importantly, get the underground tanks installed correctly. We have many installation documents and resources to make this process easier for the contractor. Sometimes site visits are required and we try to arrange those visits at a time of mutual convenience.
- Who engineers system integration with existing irrigation?
The connection to the existing irrigation system is really quite simple. Our system provides all the water pressure needed to run conventional irrigations sprayers and drippers. The specific requirements of your irrigation system should be reviewed by your installing contractor, but all traditional irrigation needs will likely be met.
- Who engineers system integration with heat exchange capabilities?
Our NEXheater is used the same as any other water heater. We can provide all necessary technical documents but there should be little to no engineering work required. The NEXheater should be installed within thirty feet of the grey water collection tank, and refrigerant lines will need to be installed between the collection tank and the NEXheater.
- What is total system weight? Size? Specs would be helpful.
Sure! See here, here, and here.
- How do I find a factory certified installer?
We are happy to pair you with an experienced local contractor, when we can. If not, we are happy to work with a state certified contractor of your choosing. Our system qualifies for PACE financing, so a contractor in a PACE network might be a good place to start looking. We typically suggest starting with HERO or CaliforniaFirst.
- How many gallons per day can the water recycling system process and deliver?
The system is able to treat up to 200 gallons per day, which is more grey water than produced in nearly all homes. The exact amount that you recycle will depend on the size of your family and how you use water. It is typical in many homes to recycle about 100-150 gallons daily.
- How do I know in real time if system water output will be safe in my garden?
The water from the spigot will always be safe. Should the system fault, for whatever reason, the system would go into "bypass" mode and the water would continue to flow into sewer until the issue is addressed. There is also an indicator light on the front panel that would illuminate as well as a beeping sound that would go off until the system is reset (note: the alarm does not go off in evening hours).
- In the event of an issue, who monitors system performance?
There is a cellular phone chip in the system that sends us and users a daily report at approximately midnight PST. It allows Nexus eWater and NEXtreater users to see their system performance from a login portal available via web browser.
- Who would replace the system in the event of failure?
System replacement is included in the warranty and is covered by Nexus eWater.
- How much is shipping typically? Where are you shipping from?
Shipping is usually around $300-$500 in California. We ship our system components from our main office in San Diego.
- Can you explain the energy saving component? I know it has something to do with water heating, but not sure exactly how it works.
Simply speaking, we use refrigerant in a heat exchange process to harvest the warmth in our grey water collection tank and transfer it to fresh new water in our water heating appliance, the NEXheater.
- What is the typical ROI (Return on Investment)? Does recycling grey water help me protect the investment I've made into my home?
The water, sewer and energy savings of using our system are quite staggering. Many typical suburban homes will see up to 30-40% reduction in the use of potable water, and up to 70% reduction in flows to sewer. With the NEXheater, the energy used to heat water can be cut by up to 80% (around 2,000 kwh annually). The ROI on these savings depend heavily on how water, sewer and energy rates are structured in your area, so each case requires its own analysis.
In areas where drought is chronic, the most tangible payback may be achieved by protecting your home’s landscape - or even having landscape at all. Even during periods when the outdoor use of municipal water is restricted (as has been the case statewide in California), homeowners are able to freely reuse water from the NEXtreater system however they want. Homeowners with lusher landscapes especially value being able to irrigate their landscape as many days as their plants need, unrestricted.
- How many retrofit installations have you provided the product for? Can you tell me in what geographical areas and point me to any that would allow me to look at them?
We focus primarily on new construction so we don't have many retrofit installations. We have a few customers who have offered to open their home up to serious buyers but we try not to impose on their time needlessly. We usually make that request only when there are large homebuilders or interested policy makers in the immediate area. However, prospective customers are always welcome to arrange a time to visit our manufacturing facility in San Diego.
- What are the barriers, in your opinion, to getting more systems installed on a retrofit basis?
The two key issues are financing and contractor knowledge. Over time, we hope that more and more contractors will become experts in fitting a system like ours into existing homes. Financing is the other issue that will hopefully be addressed in future years. Rebates, tax credits, and creative public financing are not yet widely available for whole-home solutions like ours. We do qualify for PACE financing programs (like HERO), so avenues are available.
