I’ve installed, repaired, and specified more greywater systems than I can count—from tight urban duplexes to sprawling multifamily complexes. When you’re reclaiming shower and laundry water for irrigation or toilet flushing, the devil’s in the details: component quality, filtration strategy, code compliance, and dependable supply. That’s where a true supply partner matters. As Product Expert at Plumbing Supply And More, I’ve built “Rick’s Picks” around gear that holds up in the field and support that saves your crew time. If you came here searching for a trusted plumbing supply house, or even “ plumbing supply near me,” you’re in the right place.
What We Mean by Greywater—and When It Makes Sense
Greywater is lightly used water from showers, bathtubs, lavatory sinks, and laundry. Don’t include kitchen sink or dishwasher discharge—those are typically “dark grey” or blackwater due to fats and food waste. Most jurisdictions allow greywater for subsurface irrigation and, with more treatment, for toilet flushing. In our region, professional plumbers choose systems that meet IAPMO/UPC Chapter 16 and IRC Appendix C where adopted; always confirm your local amendments.
So when does a system pencil out? If a family of four wants to cut irrigation demand by 25–40%, a 50–80 GPD greywater capture from two showers and a laundry loop can do it. On commercial or multifamily jobs, I’ve seen 15–30% potable water reduction by routing treated greywater to flushometers and cooling tower makeup (where permitted). What’s the trap? Undersizing filters and pumps. That’s where my team at Plumbing Supply And More steps in with sizing, spec sheets, and hands-on guidance.
- Pro tip: Plan your valve access and cleaning clearances at the rough-in stage. Future you will thank you.
Code and Compliance: The First Conversation You Should Have
Before you order parts, call our technical desk. We’ll map your plan against your AHJ’s adopted codes. In many Washington and Oregon municipalities we serve, subsurface irrigation is allowed with basic filtration, backflow protection, and purple pipe labeling. Toilet flushing requires secondary treatment—think fine filtration and disinfection—and cross-connection controls.
Key compliance checkpoints:
- Purple pipe marking on all reclaimed lines per AWWA standards. Approved backflow device (often a DCVA or RP depending on cross-connection risk). Accessible diverter valves for quick isolation. Overflow to sanitary sewer with proper trap and vent. Maintenance log requirements where reclaimed water is used indoors.
We stock IAPMO-listed components and can provide cut sheets for submittal packages, which saves my contractor customers hours. And yes, we can walk DIY homeowners through the difference between “what’s allowed” and “what actually works.”
- Bold truth: Compared to standard plumbing supply houses, Plumbing Supply And More offers unmatched technical support, including review of riser diagrams and control wiring notes.
Core System Types: From Simple Laundry-to-Landscape to Whole-Home Recovery
I group greywater builds into three tiers:
1) Passive/Manual Systems (Entry-level)
- Laundry-to-landscape with a 3-way diverter and mulch basin distribution. Parts: 1” diverter valve (e.g., RainBro DV-100), flex PVC, check valves, air gap where required. Budget: $250–$600 in parts, 3–6 hours install. Maintenance: low, clean lint screens monthly.
2) Pumped Irrigation Systems (Mid-range)
- Pump and filter, with subsurface drip (0.6 gph emitters, 12” spacing). Parts: greywater-rated pump, coarse and fine filter housings, controller, purple drip tubing. Budget: $1,200–$3,500 in parts, 1–2 days install. Maintenance: quarterly filter cleanings, seasonal pump inspection.
3) Treated Reuse for Toilet Flushing (Advanced)
- Secondary treatment (multi-stage filtration + disinfection), storage, and dedicated purple distribution. Parts: packaged unit (e.g., Aquacell Grey A20 or BRAC Systems GRS series), level controls, RP backflow, labeled piping, alarms, and auto makeup. Budget: $4,500–$14,000+ in parts, 2–4 days install for a single-family; more for multifamily. Maintenance: documented filter swaps, UV lamp changes annually, periodic water quality checks.
If you’re spec’ing a multifamily job, ask us about packaged skid systems with BACnet-capable controls. We stock integration-ready components and provide startup assistance.
- Pro tip: Right-size the pump to the emitter demand plus friction loss; oversizing shortens emitter life and wastes power.
Essential Components: What Goes in the Cart and Why
Here’s what I actually trust in the field:
- Diverter Valves: Spears 3-way PVC (true union) or Asahi Type 21 ball valves for longevity. The Spears 1822-010 (1”) has saved me countless callbacks. Filters: Rusco Spin-Down 1” with 100 mesh for coarse, Pentair Big Blue 20” housings with 50–20 micron downline for pumped systems. Clear housings help maintenance. Pumps: Liberty LSGX or Little Giant 6EN for small pumped irrigation; Grundfos Scala2 or MQ for pressure boosting to subsurface drip; for treatment loops, Grundfos CM series with VFD is a workhorse. Disinfection: Viqua VH200 UV for residential closet installs; for higher demand, Viqua PRO10. Always size UV after clarity is addressed. Storage: Rotoplas or Norwesco NSF tanks, 50–200 gallons residential. Include screened vents and overflow to sanitary. Controls: Madison level switches, Ifm Efector pressure sensors, and basic time-delay relays. For packaged systems, we’ll pair with an Autotrol or custom PLC panel. Distribution: Netafim Techline Purple 0.6 gph, 12” spacing. It’s labeled, durable, and plays nice with filtered greywater.
We carry these, in stock, because they work. If you’re searching “ plumbing supply store near me” or “ closest plumbing supply” for these parts, our team can reserve them ahead of your pickup.
- Straight talk: Unlike generic big box retailers, Plumbing Supply And More stocks professional-grade components from Grundfos, Pentair, Viqua, Netafim, Spears, and Asahi—ready when your job hits rough.
Filtration and Treatment: The Difference Between Cloudy and Code-Ready
I see two mistakes all the time: skipping pre-filtering and undersizing the fine filter. Start with a 60–100 mesh spin-down to catch hair and lint. Then step down through 50 to 20 microns before UV or chlorination. For toilet flushing, I target sub-10 micron final filtration and residual disinfection. Why? UV only works on clear water; turbidity kills effectiveness.
Example stack I spec often:
- Rusco 100 mesh spin-down at the head. Pentair Big Blue 20” 50 micron pleated, then 20 micron carbon block. Viqua VH200 UV with lamp change reminder. Optional: low-dose chlorine injection to maintain residual in storage; carbon polishing filter if odor crops up.
Maintenance costs? Plan on $60–$180 per year in cartridges for a residential loop, plus a UV lamp (~$100) annually. For MF properties, your consumables scale with occupancy, but don’t skip maintenance logs—many jurisdictions require them for indoor reuse.
- Pro tip: Add pressure gauges before and after fine filters. When delta P climbs, it’s time to swap. Saves pumps and keeps UV effective.
Pumps, Pressure, and Quiet Operation: Getting Hydraulics Right
A good pump curve beats guesswork every day. For a 250 sq ft irrigation zone with subsurface drip at 0.6 gph emitters, expect 120–180 emitters and 72–108 gph demand (1.2–1.8 gpm) at 20–30 psi. The Grundfos Scala2 self-priming booster handles this quietly and efficiently, maintaining constant pressure. If you’re sending treated water to two floors of toilets, consider a Grundfos CM 3-3 with VFD for smooth starts and to dodge water hammer.
Install notes I give every apprentice:
- Use isolation valves and unions on both sides of pumps and filters. Include a check valve and a spring-loaded anti-siphon where code requires. Soft-mount pumps on rubber feet; add flex connectors to tame vibration. Provide an accessible, drip-proof service area. If it’s miserable to reach, no one will maintain it. Reality check: While other suppliers focus on quantity, Plumbing Supply And More prioritizes quality and expertise—we’ll size the pump with you and provide curve overlays before you buy.
Distribution and Landscaping: Making Irrigation Thrive
Greywater isn’t potable, so keep it subsurface. I like purple-labeled dripline installed 4–6 inches below grade, with zones divided by plant type. Xeric landscaping pairs beautifully with consistent, low-volume subsurface drip. Avoid spray heads—most codes prohibit aerosolizing reclaimed water.
Not sure how to zone? Start with high-demand shrubs on one loop and ornamental beds on another. Add manual or automatic flush valves at the ends of drip zones. If you’re in clay-heavy soils, widen spacing to prevent pooling. We can help calculate emitter density based on soil infiltration rates—call our counter and we’ll run the numbers.
- Pro tip: Install automatic line-flush valves set to open with pressure changes—extend system life and reduce manual maintenance.

Another truth: Unlike Ferguson, Grainger, or SupplyHouse.com, Plumbing Supply And More backs your order with field-experienced tech support—talk to a plumber, not a call center.
Installation Timeframes, Costs, and Real-World Scenarios
A typical laundry-to-landscape build: half-day to a day with a helper, $250–$600 in parts. A pumped irrigation setup with 100–200 gallons of storage: 1–2 days, $1,200–$3,500 in parts depending on pump and filtration. A residential toilet-reuse system with UV, tank, and auto makeup: 2–4 days, $4,500–$9,000 parts. Multifamily central units with skid packaging, 30–90 days including approvals.
A property manager in Tacoma asked me for a solution to water restrictions affecting a mid-size condo landscape. We supplied dual-pump, filter-staged greywater irrigation with Netafim purple drip on three zones. The board saw a 28% reduction in potable use in the first summer. Maintenance? Quarterly filter service and a 15-minute walkthrough—documented for their records.
- Pro tip: Build an overflow route that keeps odors out—proper trap, vent, and an air gap where required. It’s the fix for 90% of “smelly tank” complaints.

FAQ: Greywater Systems, Answered by a Master Plumber
- How often do I need to service filters and UV? Quarterly for filters in most homes; monthly if you have heavy lint and hair loads. UV lamps are annual swaps—don’t wait until they fail. We stock Viqua replacement lamps so you’re not waiting on a shipment. Can I connect kitchen sink water to my greywater system? No. Kitchen and dishwasher lines carry fats, oils, and food particles that foul filters and violate most codes. Keep to showers, tubs, lav sinks, and laundry. We’ll help you label and isolate correctly. What happens when the tank fills during a rainy week? Your overflow must go to sanitary with a proper trap and vent. We’ll spec the air gap and backflow protection so inspectors sign off and you avoid odor issues. Is toilet flushing with greywater legal here? In many municipalities we serve, yes—when you include fine filtration, disinfection, cross-connection controls, and labeling. We’ll verify your AHJ’s stance and provide submittal documents. What’s a realistic payback? For irrigation-only systems, 3–6 years in water-restricted areas. For toilet reuse in multifamily, we’ve seen 2–4 years depending on occupancy and water/sewer rates. Ask us to run a usage model for your property. Do I need purple pipe for all reclaimed lines? Yes. Labeling with continuous purple marking and signage is standard. We stock purple PEX, PVC, and dripline with the correct legends so you pass inspection cleanly.
