Pool Anatomy & Systems

How skimmers, returns, drains, pumps, filters, valves, feeders, features, and shared pool/spa plumbing work together.

Chemical Feeders and Dosing Hardware

Run erosion feeders, liquid pumps, acid tanks, and injection hardware as calibrated chemical systems with real compatibility and leak risks.

Filter Service Guide

Service cartridge, sand, and DE filters with safe teardown, failure signs, and reassembly checks.

Filtration and Circulation

A canonical guide to sand, cartridge, and DE filters; clean baseline pressure; backwashing; and cloudy-water filtration fixes.

Pool Anatomy and How Systems Work

Trace the water path, normal valve positions, and owner-safe boundaries before you guess at a circulation, heating, or feature problem.

Pumps and Hydraulics

Understand flow, head loss, speed control, priming, and filter matching before you trust generic runtime folklore.

Shared Pool/Spa Systems

Understand spillover logic, valve modes, hotter-water chemistry, and shared-equipment troubleshooting for combined pool/spa systems.

Spa Spillover Advanced

Use spillover intentionally instead of treating it as a default setting, because attached spas change pH rise, heat loss, aeration, and sanitizer demand.

Water Features and Aeration

Spillovers, laminars, fountains, bubblers, and deck jets affect pH drift, evaporation, scale pressure, and scheduling.
