First check the eductor assembly. Top of valve under chrome plate. Pull it out and clean it (after bypassing and depressurizing the system) If that is OK the the brine piston will need to be replaced. There is a rebuild kit for this series valve that is about $120 that includes the refill piston and a retrofit kit. It would be wise to rebuild the valve. See your local culligan dealer RJH2O
For a pH of 6.0 to 6.9 a type of naturally occurring calcium carbonate media called Calcite is used to neutralize the pH. For water with a pH of less than 6.0, magnesium oxide is blended with Calcite to bring the pH to 7.0 or above. The Calcite or the blend of media is put in either an up-flow neutralizer tank or a down-flow neutralizer tank.
Acid neutralizer water systems are typically installed after the well pressure tank.
In down-flow neutralizer tanks the media flows from the top of the media inside a vertical filter tank down to the bottom of the tank, and up a distributor tube and out of the filter to the household piping. Down-flow neutralizer tanks also act as filters since sediment and other fine particles become trapped in the Calcite. This type of neutralizer is automatically or manually backwashed to keep the media clean.
In an upflow neutralizer the water flows down through the center distributor tube and enters the media bed at the bottom and flows up through the media before exiting the neutralizer and flowing out to the plumbing. Up-flow neutralizers do not get backwashed because the media is never compacted and no sediment is removed. Since the water is flowing up through the media the media is not compacted to theoretically it does not require backwashing.
There are advantages and disadvantages to both up-flow and down-flow neutralizers. The main advantage of the down-flow neutralizer is that it not only neutralizes the water, it also acts as a whole house sediment filter. Down-flow neutralizers are usually automatically backwashed, which cleans the Calcite media and prevents rust particles and other sediment from fouling or coating the media. Since additional Calcite or blended media must be added to most neutralizers once or twice a year, down-flow neutralizers are easier to backwash and put back in service than up-flow neutralizers which cannot be backwashed.
Up-flow neutralizers must use an internal top screen in to order to prevent the Calcite from entering the home plumbing system. Calcite has the appearance of white sand and can quickly damage valves and fixtures if the media enters the plumbing system. If the water contains iron, manganese or sulfides, these internal top screens can later become fouled and so are generally are not used for this reason. Instead of the internal top screen, a filter housing and cartridge filter are usually installed after the up-flow neutralizer tank to prevent any mineral from flowing into the plumbing system. AdChoices With down-flow neutralizers these upper screens or external filter housings are unnecessary since the Calcite is prevented from leaving the filter tank due to the bottom internal distributor screen. The bottom distributor does not get easily fouled due to the backwashing the down-flow neutralizer tank receives on a regular basis.
In filter tanks the media can flow around the media and create channels which allow the water to flow without properly contacting the media. This type of channeling is more of a problem with up-flow neutralizers and rarely happens with down-flow neutralizers due to the action of the backwash. For most residential applications down-flow neutralizers work better than up-flow neutralizers due to the filtration feature and the backwashing function.
A down-flow neutralizer can be backwashed on a regular basis to clean, re-classify and distribute the calcium media thoroughly. This backwashing allows the down-flow neutralizer to function properly and lower maintenance costs. The Calcite media dissolves better because it is cleaned and then compacted in the down-flow neutralizer tank.
Well water that is acidic can also sometimes be high in iron, manganese or hydrogen sulfide. If a greensand or other type of manganese media iron filter is used to treat the water for iron, the pH should be raised up to at least 6.8 to allow the iron filter media to work properly. A down-flow neutralizer is usually the best choice to put in front of an iron filter because the neutralizer acts as a pre-filter removing some oxidized iron prior to the iron filter. This lessens the load of iron that the greensand filter must treat. Iron, manganese and sulfides can coat the acid neutralizer media and render it unable to dissolve into the water and neutralize the pH.
There are some applications where up-flow Calcite neutralizers are more desirable than down-flow neutralizers. If the flow is more or less constant on a regular basis, such as when the neutralizer is used to fill a holding tank with neutralized water, the up-flow filter works fine. Since up-flow neutralizers have no automatic backwash control valve they are less expensive than down-flow neutralizers. If the water is of excellent quality with no sediment or iron and the flow rate is constant then the up-flow neutralizer costs less to use and uses no backwash water.
The eductor assembly is plugged or the refill restrictor in top of float assembly is plugged. The eductor/injector draws the brine in during regeneration. These need to be cleaned to remove any oxidized iron or sediment . Do you have your owners manual for your Water Gard system? RJ
If it is running small amounts of water to the drain when it is in service position this means you have a bad seal pack and it needs to be replaced. The "sealpack" is the main piston and seals that control the hydraulics of the valve. When water runs to the drain constantly either the piston is jammed (which would show an error code) or there is a bad seal causing water to get by. I suggest calling Culligan or if you are handy you can do this yourself. You need a sealpack and refill piston. It takes about 20 minutes. The kit is available from Culligan. RJ
If this is a Culligan neutralizer you will need to call Culligan for replacement parts as they are proprietary. You can pick up the seals for the by-pass at Culligan and replace them yourself. Depending on the PH of the water and your water usage the calcite should be replenished on a yearly basis. So you may want to have them out to do that also. RJ
Neutralize the acidic orange juice(squash?). A bit of baking soda in a bowl of water in which you wash the mp3(stick) should neutralize the acid. Carefully dry the mp3 stick with towels and a cold flow of air from a fan or hair drier set to "no heat" should dry it out. Give it a try, what have you got to lose?
