Where Is Hot Water Heater Bypass Valve In 1998 DS

OK... I live in Central Texas-Waco. Soon, I'll need to think about winterizing my 1998 DS. Where is the hot water heater bypass valve and how do I drain tank? I'm thinking I won't need to put anti-freeze in water lines... just drain all lines. Good or bad thinking? Where is the hot water heater tank? I know where the HW vent is but don't see a tank. Any other tips would be appreciated along with photos,

To drain the water heater tank (HOT water wouldn't need heating) open the outside door and the drain plug near the bottom of the tank usually a 1 1/8" socket, needs to be removed. Open the pressure relief valve by lifting the tab on the valve and water should drain out of the tank. If it's a Suburban WH, buy a new drain plug with attached anode to replace the old one in the Spring.

I don't know where your bypass valve is, you'll just have to search or maybe someone else will come along and share.

I'd either use RV antifreeze or an air compressor to blow water out of the lines if you can expect freezing temperatures. Gravity often won't drain everything, some lines aren't sloped to drain. I use a plug that fastens to the water hose inlet with an opening a Schrader valve fitting will connect. I set the compressor to 35-40 psi and pressurize the system, moving from faucet to faucet, opening each one and letting the water run until only air comes out. Once all faucets and the toilet are only passing air, I go back around and open all faucets and run air through for about an hour to be sure most all water is gone. RV antifreeze dumped in each trap as a final step inside the RV. I then do a final emptying of the black and grey tanks, using a Sewer Solution at home for the final cleanout for the season.

The water heater tank is behind the outside cover where you have seen the vent. The bypass valves are in the plumbing lines right next to the heater. Not knowing where your heater is located (above the floor or under in basement) I can't say how to access the water lines. To drain the heater you take out the drain plug in bottom of the tank located behind outside access cover. If it's a Suburban brand heater the drain plug will have a anode rod attached to it. When draining if you open the relief valve up top it will drain much faster. If you have access to compressed air I would blow the lines out after draining them.

Here is the thread for winterizing has pictures showing by-pass valves.
You may access beside tank in a compartment below or behind wood panel -bathroom or kitchen.
You can drain tank by removing metal nut bottom front of tank and also check the anode rod and see if you should get a new one also open the vent top of WH to allow air into tank. Make sure you close vent so next spring when you fill tank there will be a expansion air space at top of tank.
You can just drain everything using low point drains but if you in a area where temps stay low may want pink stuff to protect you elbows, toilet fittings, faucets, showers inside and out.
Blow out lines maybe all you need, do not forget the washer area if you have the plumbing.

My plumbing valves were in the bay forward of the water heater. Open that bay and look aft - there was a cut out area exposing the 3 valves. Maybe yours will still have the panel over that area?
