The Short Answer
Zurn Elkay stock (ZWS) is generally halal at the activity and known-financial-screen level, with a methodology-dependent status. Water-safety, plumbing, drainage and drinking-water products are generally permissible, but public filings do not quantify every customer or end use.

Business-activity disclosure
Zurn Elkay designs, manufactures and markets water-safety, flow-control, drainage, plumbing and drinking-water products. These products are generally permissible and support safe water access, while the filing does not provide a universal prohibited-activity numerator.
Limitation: The filing reports product and geographic categories but does not quantify a scholar-approved prohibited-activity revenue numerator for every end use or customer.
Purification
Zurn Elkay discloses $2.1 million of interest income, or 0.48% of quarterly net sales, but no scholar-approved fixed purification percentage is inferred.
Inputs, assumptions and primary sources
- Amounts are USD millions from Zurn Elkay's March 31, 2026 Form 10-Q.
- Debt combines $1.4 million of current maturities and $497.6 million of long-term debt; operating leases are excluded.
- Cash and cash equivalents are $273.5 million; no separate interest-bearing securities balance is identified.
- Receivables, net are $242.7 million and quarterly net sales are $433.0 million.
- The filing reports $2.1 million of interest income for the quarter.
This is a reproducible financial screen, not a fatwa. A failed total-assets screen can coexist with a pass under a market-cap methodology. ZakatInvest keeps the qualitative assessment separate so numerical thresholds do not erase material context.
What Zurn Elkay Does
Zurn Elkay designs and markets water-safety, flow-control, drainage, plumbing and drinking-water products. These products support safe water access and are generally permissible. Product and customer end uses remain a qualitative question.
Current Quantitative Screen
The March 31, 2026 Form 10-Q reports $2,684.4 million of assets, $499.0 million of interest-bearing debt, $273.5 million of cash and $242.7 million of receivables.
- Debt/assets: 18.59% — below the examined limits.
- Liquidity/assets: 10.19% — below the examined limits.
- Receivables plus cash/assets: 19.23% — below the examined limits.
- Interest income/revenue: 0.48% from $2.1 million of disclosed interest income.
Known financial ratios pass FTSE, MSCI and Malaysia asset-based limits; the overall result remains incomplete for activity classification and purification.
Purification and Qualitative Review
The disclosed interest-income ratio is below the examined FTSE income limit, but it is not a fixed purification prescription. Follow the guidance of a qualified scholar or the methodology you use.
Bottom Line
ZWS is generally halal at the known-screen level, with a methodology-dependent status. Re-screen after a newer filing, acquisition or material product-mix change.
