I'm putting a new bathroom in my MC-9 and putting in an RV toilet with holding tank should I hook the water directly into the toilet with plastic pex pipe or should I use a flexible steel pipe like under a sink. | ||

Amen to that shut off valve, mine froze once and leaked all over my carpet. I had to shut off the whole water system because there was no valve to the toilet. Also make it so when the valve is shut off you can unhook the toilet supply line past the valve and drain the toilet. Then you can open the valve and drain the rest. The toilet flush valve is one of the worst things to freeze and crack in the whole system, the only part I've ever had freeze, crack and leak. I used clear plastic tubing between the shutoff valve and the flushing valve so I can see for sure it is drained. (Message edited by gusc on July 22, 2010) | ||

Gus' problem is yet another reason not to 'drain' your system. I hook up shop air through a regulator and blow it out. No antifreeze, no hot water bypass, no need to flush system (but I still do), and ready to fill and go at a moments notice. Works even better for boats too. They are a pain to flush since in mine there is no drain. It must be pumped out. Save the pink stuff for the drain traps. Also stopped the horrible smell that can develop in the hot water tank which I assume has something to do with the pink stuff. Good luck Don 4107 | ||

My toilet flush valve is the only thing that does not drain. I didn't know how it worked until it froze after owning it for four years, now I know how to prevent freezing. I'm not crazy about blowing such a low pressure system out with shop air. | ||

My toilet flush valve is the only thing that does not drain. Perhaps , we have found that sinks with diverters and hand sprayers , also do not drain . FF | ||

Gus, I always use a regulator set to about 40PSI. Same pressure that the city hookup regulator is set to. I drain the fresh water and hot water tanks then run the pump to clear it. Hook up regulated air. Go to the longest runs (kitchen sink) and run until completely empty. Do the same with all the others. Repeat until no more water. Ten minutes tops. In the boat I have to remove one line from the pump do to the way it is located. When you are finished blowing out the system, you are also ready to refill and roll without any other work. I usually flush the freshwater tank with a mild bleach to be sure after sitting for a long time. We don't drink water from the tank so it is probably wasted effort. Good luck Don 4107 | ||

Don, I forgot about those sprays, they have frozen also. I'm beginning to change my mind about your air blowing system. We also use a slight bit of bleach in our fresh water tank at the beginning of the season, but very little. We drink out of it after it has been used for about a week, never any problems. | ||

for you guys who use bleach to sanitize your fresh water tanks, here is a bit of info you may not know about. Household bleach is about 3 to 5 % when they make it. The active part that will kill bacteria and such is sodium hypochlorite. This is not a stable compound and as such has a fairly short shelf life, usually about 90 days and so the manufactures add chemical stabilizers to it to make it last longer. They also add scents to it to make it smell better. Long and short is you are getting a lot of chemistry in your water tank that is very much not "good for you" Can I suggest that you use a more pure form of chlorine like the type that is used in swimming pools? Calcium hypochlorite. It is 66 to 70% and has no stabilizers or perfumes or better yet use hydrogen peroxide. Simple chemistry, no by products, taste or smell and a faster better kill of any microbiological infection in the tank. 1/2 liter or 1/2 quart per 100 gallons of water of 3% hydrogen peroxide will kill any infection without leaving much residual For smaller holding tanks about 1/2 cup per 25 gallons. Fill your tank with water let it sit for 10 min. drain, refill and you are ready to go with a sanitized water tank. Hydrogen peroxide is found in almost all drug and grocery stores Les | ||

Thanks for the good info Les. I have always used bleach, but bought the cheapest stuff I could find with no scent figuring it was less chemicals. I sure like the hydrogen peroxide idea, never had heard of it before. John | ||

I had a custom copper ball valve manifold made, one for cold and one for hot with an individual ball valve for each water application. Pex makes pre made plastic manifolds. Since you don't use them much, I'm going to use the plastic one. You have the choice of the number of valves and the valve block is compact-plus a heck of alot cheaper then the brass one. Good Luck, TomC | ||

Les, Once a year we fill the cap from a small bottle of bleach for 100 gal of water. Although HP is probably better, I doubt there is much chemical risk from that small amount of bleach. I plan to give HP a try next time but not anywhere near 16 ounces for my 100 gal tank. |
