I noticed a rotten egg smell when using the "fresh" water this weekend. I had the fresh water tank almost empty and added about 5 gallons of water this weekend. When I went to use it, the smell was bad. What is the recommended way to get rid of this smell?

Sulfer

Rotten egg smells are usually the result of sulfur in the water you put in the tank. Some areas get that from time to time. This is especially true if the water comes from well (municipal or private) . Replenishing with fresh water and thoroughly rinsing might get rid of it. Hope that helps

Hydrogen sulfide

This gas is a byproduct of natural processes in the ground and is prevalent in some areas more than others. Conditions with little or no oxygen tend to promote its formation. Hydrogen sulfide is highly soluble in cold water, which is probably why you didn't smell it coming out of the faucet. However, the tank on board warmed up and some of the gas came out of solution, hence the smell. A little bleach in the water should cure the problem. Peter H23 "Raven"

Possibly...or--

it may just be way past time to recommission the system. Complete directions for doing that are in the archives.

baking soda

flush it out with a mixture of baking soda and water after letting it sit over night

Drain the fresh water tank?

Is there an easy way to drain the fresh water tanks without having to *pump* them completely out? The boat was delivered with them filled and we rarely use the water...

Easy way to drain the tanks: turn on every faucet

and let the water run till the tank(s) are empty. It's important to use your water...so that it has to be replaced often and doesn't sit in the tank long enough to become stale. A 26 boat, unlike a 40'+ boat, doesn't hold enough water to make it very much of a job to drain and replace it every few weeks. It's not good for your water pump--or ANY equipment--to sit unused...the rubber parts in it dry out...lubrication in the motor settles to the bottom of the housing... Far more equipment fails prematurely due to lack of use than heavy use. Baking soda may "sweeten" the water somewhat, but it won't kill the molds, fungi and bacteria growing in the plumbing that are the real cause of foul water odor and taste. The only way to do that is by recommissioning the system with chlorine.

No Faucets in a 260

Unfortunaltely, htere are no faucets in a Hunter 260 - they are manual pumps. I put a bilge pump in the bow, in front of the water tank, and I empty the tank by removing the fitting at the bottom of the tank. The pump sends it overboard, and I just dry up the remaining few ounces.

Chlorine Bleach

Put about 1/2 c. bleach in the water tank. Pump water thru both faucets for a minute. Then let is sit overnight. Pump it all out, refill and pump out 2 more times. Then each time you fill the tank (especially from your local marina), add about 2 T. of bleach per 30 gal tank, each time you refill. Of course the problem is draining the tank. It takes forever using the sink faucet pumps. Try using a drill pump that attaches to your electric drill. Speeds it up a little.

Not enough bleach to accomplish anything

Recommissioning a system requires a solution of 1 pint of bleach to 25 gallons of water...and it has to remain in the plumbing long enough to do any good. You'll find complete directions in the archives (and in my book...see link below).

Draining water tank on trailer

When I lay up my boat for the (hot!!) summer on the trailer I drain the 13 gal. flex tank in the bow. I used to do it with the electric pumps, but now I have about a 15' length of clear vinyl tubing that fits on the spigot of the faucet, and goes thru the cockpit and under the engine mount and lays on the ground. A few pumps of the faucet pump starts the siphon effect, and draws about 1/2 gal per minute out the vinyl hose. It drains as much water out as the electric pumps do, with no wear and tear. I've done it several times and it works. Of course, it only works because of the height of the boat on the trailer above the ground.

I agree with the Bleach

Bleach has been used by DoD and FEMA for years now. 1oz per Gallon ,(I use 3oz pr Gal) is the best solution to any Infections, Biocides, Contaminents or Oders in Fresh Water Tanks. It also makes Stored Water last longer.
