Describe the pool once — get the Hayward shopping list, the panel wiring, and the plumbing layout, all in sync. Here’s the lay of the land.
The summary bar across the top always shows Total Volume, Governing Flow (the largest flow the plumbing must carry), Estimated TDH (Total Dynamic Head — the total pumping resistance the pump must overcome, in feet), Breaker Slots used, and Build Status. Status goes amber (“N to fix”) whenever something needs your eye — an over-pinned pump, a pin that changes other gear, a disabled SKU in the quote — tap it to jump to the fix. Clear them all and it turns gold: ★ Trail Ready, the stamp appears on the printed quote, and a permanent star lands on your record — the tally and your rank (Greenhorn → Ranch Hand → Wrangler → Trail Boss → Legend of the Trail) live in My Builds. If a change moves a number in a way that surprises you, the Show Work tab explains why.
The full Hayward order, grouped the way you’d buy it — pumps & filtration, lighting & automation, electrical, plumbing. Rows starting EST_ are jobsite estimates (pipe footage, conduit): verify on site. Tap any equipment SKU to swap it — the list names each model and shows which alternates fit this build; your pick pins purple and the whole quote re-computes around it — amber means your pick also changes other gear (the Notes list what), red means it can’t carry this build’s load (choose the “(recommended)” entry to hand the choice back, or Clear pins in the toolbar to drop them all). Counts are tappable too — change a light or feature quantity right on its row and the whole build follows. Tap why? on a line for the reason it won; Compare Sizing shows Minimum / Recommended / Oversized side by side. Copy SKUs puts the whole order on the clipboard.
The Omni panel as your electrician wires it: breaker slots with 2-pole pairs marked black/red, high-voltage relays laid out like the physical board, low-voltage heater relays, GVA valve actuators, the RS485 bus, and the lighting transformer. Equipment SKUs on the breaker rows and connection spots are tappable to swap, right from the wiring view.
Pool and spa drawn to scale with the equipment pad: suction → pump → filter → heat → sanitize → returns. Pipe sizes are marked on every run, each valve and check valve sits where it belongs, and the Schedule-40 PVC estimate rides up top. Tap the SKU inside any equipment card to swap that piece of gear in place.
The complete calculation trace — volume, turnover, TDH, and why each SKU beat the alternatives. When a pick looks odd, the answer is here.
The whole Hayward reference library. Search by SKU or description; switch a SKU off and the engine specs the build around it.
Every output is a planning estimate — verify equipment, breakers, and plumbing against the official Hayward installation manuals and your local code before you build.
