This is a rather standard modification but just in case you have not seen it here it is. We do not like the idea of having water sitting in the hot water heater (10 gallons) for several weeks or longer after it was heated up and now sits in the hot sun especially when it quite likely was well water to begin with. So we just gave up $5.98 and installed a hot water heater drain. Now after we get home (I don't like to drain it at the camp site) we drain the heater. You do have to make sure you refill the heater before you turn on the heater on next use but no big deal. Also is handy for winterizing.

I bought the brass drain from my local RV dealer. There was a good thread started by DANSKOOL a while back that will give you all the info you need:

I hope that takes you to it. If not you can just scroll back thru previous mods posts to find it. There was a lot of good info on the hot water drain thing

Theissue with this set up is it does not drain fast enough to flush any sediment and since it is a copper bearing alloy (brass) it will cause corrosion with the aluminum tank over time.

I have not done this on the Cruiser, but on my last unit, I installed a CPVC ball valve and it did not limit the flow as much as a brass petcock. But in either case, there is a lot of water at the bottom of the tank which doesn't get drained even when the nylon drain plug is removed. You can get more stale water and sediment out of the tank with a wet/dry vac and a small diameter plastic hose.

I installed a ball valve on my Cruiser. When I return from outings I connect to the city water. Then I open the ball valve and get a very strong folw that should flush most of the sediment. Iflush until the water runs cold and close the ball valve. If my next trip is in a couple weeks I leave the tank full. Then when putting water in fresh tank before next trip I connect to city water again and flush hot water tank before the trip.

Ken --



Doesn't your Kingston have a hot water drain already in the convienence center? When I open my, hot water pours out, so I figured it was draing the water heater.
