Question for Peggie
Peggie,
I see some rather pricey system for pumping air into holding tanks to aerate them. I'd like to try rigging up my own. How much air does it take? Is there a critical amount below which nothing useful happens or does any air help? I'd like to avoid the 12 volt drain. Since we are in an area where there will usually be wake motion, I have an idea for boat motion powered pump. -- Roger Long |

Is there a critical amount below which nothing useful happens or does any air help? The Groco Sweetank pump moves 1.7 liters of air/minute, which is about the minimum that'll work. Two things are important: a sufficient amount of air to aerate the contents, and piping to distribute it throughout the tank. Otherwise it'll only push foul gasses out the vent all the time instead of only when the head is flushed. You can see the compete manual for the Sweetank he http://www.groco.net/parts/data/622.pdf I'd like to avoid the 12 volt drain. Since we are in an area where there will usually be wake motion, I have an idea for boat motion powered pump. I don't think it would produce enough air. The Sweetank requires only 3 watts of 12v power...not much of a battery drain. If even that's too much for your current 12 resources, a relative small solar panel would replace the drain on your battery. It's price of $150-200 seems expensive...but the purchase price is offset by what you're spending for tank products now, 'cuz a properly aerated tank requires nothing else. So depending on how much you're spending for tank products, the Sweetank can pay for itself in just a few years. -- Peggie ---------- Peggie Hall Specializing in marine sanitation since 1987 Author "Get Rid of Boat Odors - A Guide To Marine Sanitation Systems and Other Sources of Aggravation and Odor" http://www.seaworthy.com/store/custo...0&cat=6&page=1 |

Over the weekend I noticed that the access port cover for my holding tank seems to have a small leak between the tank and the screw-on (or in) cover. Seems to be a chronic problem, since I had the tank pulled a year ago (another story) and some new fittings installed, and at that time I saw that the PO had tried to seal the port cover by putting some silicon-like material around the sides of the cover. What's the most effective way to make a good non-leaking seal for that fitting? Rubber gasket...or, if the cap is round, rubber o-ring, which you can find if you google Beckson (they make inspection port retrofit kits). Call 'em and give 'em the size. O-rings should be replaced about every 5 years or so. -- Peggie ---------- Peggie Hall Specializing in marine sanitation since 1987 Author "Get Rid of Boat Odors - A Guide To Marine Sanitation Systems and Other Sources of Aggravation and Odor" http://www.seaworthy.com/store/custo...0&cat=6&page=1 http://shop.sailboatowners.com/detai...=400&group=327 |
