Alright, swampers
I'm putting up two on my shop. Are the devices that dump the water
every day worth the $40? Do they work? Any other devices that work and are worth the money? Steve |

He's talking about evaporative cooling units . They pump water from a sump at the bottom over a fiber pad , then suck air thru same pad to cool by evaporation . Most units will have 3 pads and the outlet on the 4th side . Better ones will have a float valve to maintain water level in the sump . What Steve is talking about is a device that drains the sump daily , which probably helps keep mineral deposits out of the pump and off the pads . FWIW Steve , you can probably use a light timer to actuate a solenoid daily and save a wad of money . Use dual relays and a dashpot delay on the end of cycle to let the supply water run a minute or two to rinse the sump before the drain valve closes . -- Snag |

Steve I can't say about those devices but my experience with using re circulating pumps on swamp coolers compared to just running the water thru once and out to the lawn is that recirulating the water is VERY hard on the cooler causing a lot of corrosion and gunk build up, far in excess of what you get running the water thru only once. I also had a water cooled outside AC Condenser that bleed off water when running to try and keep the salt buildup from being as bad. It still built up a ton of crap. For $40 I'd do it as it will surely be better then not doing it. |

And where do you live? I think the minerals will still build up on the pads. I had a unit in an apartment. I did a little maintenance on it once in the 5 years I lived there. I don't even think I shut the water off. It went to 17 degrees once. That was in the high desert of ca. Low desert gets hotter. It brought down the temp 20-25 degreesm with 20 % humidity with a small unit. Here in Pittsburgh it's not going to work, but they still use misters on fans in sports and in some open buildings.

Since swamp coolers are typically run in regions where drought is a concern, they may be somewhat useful in reducing water use. Not convinced either solution will prevent scale buildup. Just do a good job cleaning after each season. |

Don't know the actual name right off, but it is a pump, very similar to the cooler pump that dumps the water in the tray once a day to prevent mineral buildup. $40 or so. Steve |

I live in Phoenix, where the water can be very hard, and I don't think dump valves help. What helps is having the swamp cooler made out of stainless steel, fiberglass, or plastic, but I think all blower impellers are made of galvanized steel. Remember the evaporative cooling index, which shows how cool a swamp cooler can make the air, for any given combination of outdoor temperature and humidity. They don't work very well above 20% RH. |

I forgot to mention that swamp coolers seem to use just as much
electricity as air conditioners do, now that A/C efficiency is so much higher than it was in the EER 7 days. |

I still am placing an anode in there. Steve You can buy a very cheap little fitting that goes in the water pump line that permits a little hose to be attached and feed that out through the tray drain. It slowly drains the tray as long as the pump is running. That and water softener - a white block or a mesh bag with a white chemical in it - in the tray helps me get by. A minimum of scraping to prep the cooler this spring. I have very hard well water. -- "Things would be a lot nicer if antique people were valued as highly as antique furniture!" Anon |

This is the best answer..
A small bleed valve that takes say 10% of the circulating water and dumps it out on the lawn. This keeps the level of minerals from building up to no more than 10x the incomming water. It has the same effect as the auto dump but is less expensive and more reliable and does in effect the same thing. Mark |

Bleed valves use a lot of water - far more than than dump pumps. If water supply isn't a concern, then a bleed valve might be the right choice. That said, unless you are having problems getting a swamp cooler to run a complete season, mineral buildup on the pads isn't really a problem that requires either solution. Mineral buildup in the pan can be dealt with during routine end of season maintenance with a mild acid solution. I guess we come from different parts of the country. I have seen where a crowbar, sandblaster, and muriatic acid would be laughed off. Steve |

Same here, but that's usually because the only end of season maintenance is to insert the damper plate and maybe throw a canvas cover over the unit. The following spring they might put in new pads every other year. If you do the correct maintenance every fall shutdown and replace the pads every spring, you don't get that kind of buildup. People want maintenace free swamp coolers and there ain't no such thing. |

There is no "best" answer, only tradeoffs. Bleed valves use a lot of water - far more than than dump pumps. If water supply isn't a concern, then a bleed valve might be the right choice. if the dump pump dumps say 20 gallons a day or you use a bleed valve and set it to bleed 20 gallons a day then the water usage and cleaning effect are about the same. Not exactly the same i grant you but close enough that it isn't worth the cost and complexity of the dump pump. And if the bleed water goes to water the grass or garden, then it isn't really "wasted". Yes you have to adjust the bleed valve carefully so the percentage of water being bled is low. I had a long tube that led down to the garden at ground level and a valve on the end that i could adjust the flow without going on the roof. Mark |
