Summerizing Titanium Water Systems
Install charged battery or have access to shore power. Turn on the battery disconnect switch if installed.
Replace external filter (if used). Always use the filtered water to fill the tanks and this will avoid fresh water tank contamination.
Close low-point drains for hot and cold if open.
Close black and gray tank dump valves if open. Open drain cap carefully and drain any discharge into a container and dispose it in proper sewer system.
Close hot and cold valves for clothes washing machine, if installed. Prepare for use according to manufacturer’s instructions
Close water tank drain, if open, and fill water tank with enough water to flush all lines, fittings, and the hot water tank. Approximately ½ full should be enough.
Close the hot water heater drain by reinstalling the nylon plug located behind the outside water heater door. Use Teflon tape or pipe dope on the plug threads. Do not over tighten. Do not substitute a metal plug in lieu of the nylon plug or it will become ‘welded’ to the water tank by electrolysis and ruin the tank. Note: due to construction materials, there is no sacrificial zinc anode used in Atwood water heaters.
Reverse the three bypass valves to the ‘summer’ positions shown in the Glendale manual or sticker on the side of the water heater (inside camper). The cold-in and hot-out valves should be open, and the valve connecting the red and blue hoses should be closed.
Energize the water pump and fill the hot water heater tank with water by opening the bathroom sink hot water faucet to purge the hot water heater tank of air. You may want to open either the inside or outside shower hot water faucet in lieu of the sink faucet as the escaping air will spit and splash.
Visually check for any water leaks in the basement around the water pump, under bathroom sink, under kitchen sink, toilet sprayer, shower tub, by the water heater, low point drains, external shower, drain plugs toilet and shower traps. If the water pump stops and does not cycle, you can reasonably assume there are no leaks. Fix any leaks found. At times the water pump may run after drawing water as there could be some remaining air pockets in the water lines. If this occurs, the air pockets should be eliminated after a few minutes of water use.
Continue flushing water through all faucets, inside shower, outside shower, and toilet(s) until no pink antifreeze is present.
Sanitize the water system:
Fill the water tank with a solution of ¼-cup bleach for each 15 gallons of tank capacity (yields 50ppm). Mix the bleach in a 2 to 5 gal pale of water. Never pour concentrated bleach directly into the water system.
After adding the bleach solution, top off the fresh water tank with water.
Open each hot and cold valve, one at a time, and close when you smell the bleach. Note: the first hot water faucet will take some time to cycle the bleach solution through the hot water tank and line.
Let bleach solution sit for a minimum of 4 hours.
Drain the water tank by opening the external drain valve under the camper and close the valve when drained.
Refill the water tank, and run water through all faucets, hot and cold, until all traces of bleach smell are gone. Normally bleach will dissipate by itself in about 1 day.
Refill the water tank and it is now sanitized and ready for use.
Install new under sink water filter at this time, if equipped. The cartridge container will be full of water so be careful.
Insuring the water heater now full of water, you can enable the water heater circuit breaker at the power distribution panel and use the water heater with either electric and/or LP.
Dump your Black and Gray tanks at an RV dump station.
