What does my NU Aqua System warranty cover?

When needed, NU Aqua will provide:

Keep your receipts and maintenance records. NU Aqua may request them during a claim.
Do water conditions affect warranty coverage?
Yes, your feed-water conditions can affect warranty coverage.
Important conditions include:
- Water pressure

- pH level
- Total dissolved solids, also called TDS

Note: Damage caused by unsuitable water conditions is not covered.
Your system must stay within its listed operating range to be eligible for warranty coverage. Operating outside of these ranges may impact warranty coverage.
Proper operating ranges are found in your Installation and Owner’s Manual.
Operating ranges may differ between NU Aqua products.
- For example, a tankless RO system may have different limits. A whole-house system may require another operating range.
Is an NU Aqua warranty transferable?

Warranty coverage only applies to the original purchaser. Coverage ends when the product leaves that person’s possession.
Keep your original receipt or order confirmation. It should show:

- The original seller
- The original purchaser
NU Aqua may request this proof during a claim.
The following products are also not eligible for warranty coverage:
- Used products
