What this video covers

Dan and Kika install a custom freshwater plumbing system on their boat, prioritizing efficiency and tank protection. Dan replaces the hot water heater’s 500-watt element with a 1200-watt version to reduce heating time to approximately 15 minutes, opting against an instant hot water heater due to the high power requirements of 5–15 kilowatt elements.5:08 He uses stainless steel braided lines for the hot water output to withstand higher temperatures, while using PEX tubing for cold water intake.4:22 The system includes a check valve, isolation shut-off valve, and a solenoid valve wired to a float switch to prevent accidental tank overflow during dockside filling.16:17 A secondary valve configuration allows the onboard pressure pump to divert water to a deck hose for rinsing the anchor chain.15:38 The installation also incorporates a pre-filter and pressure reduction valve for incoming dock water.15:53
