Tim and Peggy Posted November 7, 2020 Report Share Posted November 7, 2020 I am trying to determine the capacity of the fresh water storage tank. Like I am sure many would agree the manuals for motor homes (most) are generic. I cannot seem to find the answer. I am trying to clean/flush the tank with Clorox and don;t want to over due it. Thanks. Quote Link to comment Share on other sites More sharing options...
mptjelgin Posted November 7, 2020 Report Share Posted November 7, 2020 From an RV Trader ad for a 2016 THOR MOTOR COACH TUSCANY 42GX, Tank capacities: Fresh/Gray/Black: 91|51|51 From an RV Trader ad for a 2016 THOR MOTOR COACH TUSCANY 40DX, Fresh water 91 gl, gray & black 51 gal each From an RV Trader ad for a 2016 THOR MOTOR COACH TUSCANY 36MQ, Water Capacity: 90 So it looks like you will be somewhere around 90 gallons assuming that your coach is in that size range.

Kirk W Posted November 7, 2020 Report Share Posted November 7, 2020 (edited) With 1/4 cup per 15 gallons, it really doesn't need to be exact and a bit more would harm nothing. A tank of 90 gallons would need 1.5 cup, but if you use a little bit extra it won't matter. I have used as much as 1/4 cup per 10 gallons with no ill effects. To remove the bleach odor and taste, mix 1/2 cup of baking soda with a gallon of water and pour into the freshwater tank. Fill the tank completely and pump this solution through the water heater and the rest of the water lines. Driving the rig around the block will slosh water around and thoroughly clean the tank. Allow it to stand at least two hours, then drain it and that will remove any unwanted taste. Edited November 8, 2020 by Kirk W Quote Good travelin !...............KirkFull-time 11+ years......

mptjelgin Posted November 7, 2020 Report Share Posted November 7, 2020 If the desired ratio is 1/4 cup per 15 gallons, a 90 gallon tank would call for 1 1/2 cups.

sandsys Posted November 7, 2020 Report Share Posted November 7, 2020 I poured bleach into a glass measuring cup which then gave me a spout to pour the bleach into a hose. I ran some water into the hose first, added the bleach, added more water. That system worked well.

I have done it that way and I have also removed the filter cartridge from our "whole house" filter housing and put the bleach there. Either way runs it through the hose and so sterilizes it in the process. Quote Good travelin !...............KirkFull-time 11+ years......
