Entirely client-side: pick a pump, filter, and electricity rate, and it estimates running cost, water turnover, and the cheapest schedule to hit a turnover target. Three tabs:\n- **Setup** — choose a pump (large variable- and single-speed library across Pentair / Hayward / Jandy / Sta-Rite / Waterway / value brands), enter speed programs (RPM + min/day) or a single-speed runtime; set pool volume, filter (DE / cartridge / sand library, or custom max GPM), and plumbing complexity (a head-loss derate); set the electricity rate by **ZIP** (→ state average), **manual**, or **Time-of-Use** (off/peak).\n- **Results** — live cost/day·month·year and turnover; a recommended **optimized schedule** (single- or two-speed skim+circulate) to hit a 1.0 / 1.5 / 2.0× turnover target at lowest cost, with one-tap \"apply\"; a per-speed cost breakdown; filter-overflow warnings; a turnover-time reference; and a Charts & Curves panel (daily schedule, power curve vs cube law, GPM vs filter limit, cost-per-turnover vs RPM).\n- **Compare** — save up to 8 configurations (current or optimized) and compare as cards or a table, plus an annual-cost bar chart.\n\n**Live:** https://wohara010--9de0ccb6135711f183cd42dde27851f2.web.val.run\n\n## Standalone (despite the `PLA-` name)\nNamed for and branded to the APEX Pools business, but there's **no runtime coupling to `PLA`** — no shared database, no cross-val fetch. Unlike `pool-pricing-calculator`, this is fully self-contained (a field/customer pump-sizing tool). Its only state is browser localStorage.\n\n## Files\n- `main.tsx` (http) — the entire app. The handler just returns one big `HTML` string; all logic is client-side JS inside it. No API routes.\n\n## Storage\nBrowser **localStorage** only (key `pla-vsp-state-v2`): pump, filter, pool volume, head factor, rate/TOU settings, speed programs, recommender target, and the saved comparison list. No server-side storage, no auth, no cross-device sync.\n\n## Baked-in reference data (edit these to update)\n- `VS` — variable-speed pumps, each with a power curve `[rpm, gpm, watts]`.\n- `SS` — single-speed pumps (watts / gpm / amps / volts).\n- `FILTERS` — DE / cartridge / sand filters + max GPM (+ `custom`).\n- `SR` — per-US-state residential $/kWh (EIA Aug 2025 / NEADA), plus a `z2s()` ZIP-prefix→state table.\n\nThese are point-in-time reference data — the rates are dated **Aug 2025** and will go stale.\n\n## Cost & optimizer model\n- **`costSegs()` is the single source of truth for all $ math.** Segments are `{watts, hrs}`. Flat rate = watts/1000 × hrs × rate. **TOU:** off-peak hours are a shared daily budget the highest-wattage segments claim first (optimal placement + the app's stated scheduling assumption); hours beyond the off-peak window bill at peak. Per-segment costs always sum to the total.\n- `interp()` interpolates the pump curve at an RPM; `effGPM()` = min(rawGPM × headFactor, filterMax) — plumbing derate + filter cap. Over-pumping past the filter max adds cost, not turnover credit (the \"over\" flag/alerts).\n- `recommendSchedule()` searches single- and two-speed plans, capped at 16h/day, durations rounded up to 15-min steps, preferring the simpler single-speed unless two-speed saves ≥3%.\n\n## Env vars\nNone.\n\n## Gotchas / conventions\n1. **All client-side** — edit cost logic only in `costSegs()`; everything else derives from it.\n2. **Reference tables go stale** — updating pumps/filters/rates means editing `VS` / `SS` / `FILTERS` / `SR` (rates are EIA Aug 2025).\n3. **localStorage-only state** (`pla-vsp-state-v2`) — no server persistence, no PLA coupling.\n4. **TOU is an assumption**, not a real utility schedule (highest-wattage-off-peak-first).\n5. **Turnover credit is filter-capped** — flow above the filter's max GPM is billed but not counted.\n6. ZIP→state is an approximate prefix-range map; unmatched ZIPs fall back to manual rate entry.\n\n## Working on this val\n- This README is the context file; keep it accurate if the tabs, the baked-in pump/filter/rate tables, or the cost model change.\n- One file with an inline frontend and no backend — verify with a request to the live URL and by exercising Setup → Results → Compare.\n",[182],"pulls","branches","forks","envVars",{"_194":111,"_196":111},"connections",{"_194":111,"_195":111},"count","unfilledCount","emptyCount",{"_31":181,"_13":182,"_60":183,"_41":-5,"_33":34,"_172":131,"_174":164,"_35":203,"_37":111,"_63":51,"_177":185,"_65":24,"_179":-5,"_200":204,"_146":205},{"_31":171,"_13":62,"_60":61,"_41":-5,"_33":34,"_172":173,"_174":164,"_35":199,"_37":176,"_63":64,"_177":178,"_65":24,"_179":-5,"_200":201,"_146":202},["D",1786013799070],"children",[],[62],["D",1786841571529],[],[182],["D",1772140245683],{"_11":12,"_145":68},{"_11":12,"_140":141,"_67":68,"_25":66,"_142":143,"_144":24},{"_37":131,"_13":16,"_31":34,"_132":96,"_133":-5,"_134":-5,"_135":-5,"_136":-5,"_137":-5,"_138":14,"_139":12},"ctx",{"_49":-5,"_166":243,"_244":245,"_246":247,"_248":24,"_249":24,"_250":24,"_251":164,"_252":-5,"_253":-7,"_254":-7,"_255":111,"_256":24,"_257":24,"_258":-5,"_259":24,"_260":24,"_261":24,"_262":-5},"ENV",{"_214":215,"_216":217,"_218":16,"_219":220,"_221":222,"_223":224,"_225":226,"_227":228,"_229":230,"_231":232,"_233":234,"_235":236,"_237":238,"_239":240,"_241":242},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","811aa22498c9b0b5a47e8d778de579cdb990f332","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
