The Sulfur Eliminator looks interesting however we have a pitless well and the water line is buried 6' deep. I am only looking to treat the water for household use. The Dosematic Superdose is a proportional injector so it will vary the injection amount based on the flow through the unit to maintain a constant percentage of chemical to water. The 2.5% model can be varied between .2% to 2.5% injection rate. Just looking to see if anyone has any experience using this model of pump for this purpose. There is also another mechanical injector called the Chemilizer however the reviews seem fairly poor on that one.

Installed the grundfos pump last year and the system has been working great however we have a bit of rotten egg odor from hydrogen sulfide. I am looking at installing a hydrogen peroxide system to oxidize the H2S. I have been looking at different injection pumps and most either are wired to turn on with the pump and inject a fixed amount, use a flow sensor to turn on with the pump and inject a fixed amount or inject a fixed amount based on a timer. Since the amount of water we use in the house varies a lot and most of the time the pump is on is for outdoor uses I would like to install a proportional injection system. Stenner does make a proportional controller but it is rather expensive and I prefer to keep things simple. Any thoughts to using a mechanical pump like a Dosematic Superdos 20 2.5% pump to inject the peroxide? It is rated to 100 PSI for use with most chemicals and the injection rate can be varied between .2%-2.5%.

Picked up the pump and motor the other day. They came in two separate boxes so I will need to put them together. Looks pretty straight forward. Anything I should be aware of prior to bolting them together?

Another question. Grundfos and Franklin Electric both recommend a minimum flow of 13 gpm when used in a 6" well to cool the motor. Since there will be extended periods of lower flow (say 3-4 gpm while showering) would installing the pump in a 4" sleeve be a good idea? In a 4" well the minimum flow for adequate cooling would be 1.2 gpm.

On the product information page it says the CSV1W is adjustable between 50-65 PSI. Is this not correct?
For the 16S15-14 I have found a few sources. One is a dot com for $655 including shipping and would be the Grundfos pump and Grundfos motor. The other is a locale contractor supplier for $694 plus tax and would be the Grundfos pump end and a Franklin motor. Which motor would be better, the Grundfos or the Franklin? Also, I have heard some people have had problems getting there pumps warrantied through Grundfos if purchased through a dot com. Any truth to this? The locale supplier is listed on the Grundfos website as an authorized retailer. While I do not expect to have any problems it never hurts to consider all possibilities.

Ok, I found some more information on Grundfos well pumps (there website is not very user friendly). I am looking at either the 16S15-14 or the 25S15-9. The 16S15-14 will do 18.2 gpm at 50 psi at 120' and 20 gpm at 30 psi at 120'. The 25S15-9 will do 12.3 gpm at 50 psi at 120' and 23.7 gpm at 30 psi at 120'. I am leaning more towards the 16S15-14 as it will put out more pressure which will be useful if I use impact sprinklers on the pasture or yard(gardens will be all drip tape). Interestingly the 25S15-9 has a lower list price then the 16S15-14, I would assume because it uses the same motor and fewer stages. So my plan will be to use the 16S15-14 set at 140' on 1.25" 200 PSI poly pipe with a CSV1W and a 20 gallon tank. (I already have the pipe, csv and the tank). Earlier you said the CSV1A would be better then the CSV1W. What are the differences and what would make one better then the other in this situation?

I am starting to think I am on a snip hunt looking for a pump with fixed stack impellers. I found the Betta Flo is made by National but has "Impellers and diffusers are glass filled Noryl." Even the Grundfos are plastic impellers as described on there web site "The SQ/SQE pump design uses "floating" impellers. Each impeller has its own tungsten carbide/ceramic bearing." It would appear every manufacturer I can find information for is now using floating impellers. Are there any pump models that still use a fixed stack impeller?

At 60 PSI I will only need a max of 10 gpm for household use, the static water level is at 46' which I rounded to 50' and then 15' of head for loss in the pipe would be 10 gpm at 215' of head. I do not plan to irrigate and shower at the same time. For irrigation use the drip tape only needs 10 PSI so for irrigation I would like 20 gpm at 80' of head. Looking at the BF-2008 chart it puts out 10 gpm at 230' and 20 gpm at 190'. That should give me 51 PSI at 20 gpm which will be more than enough for irrigating. The Myers pump would give 240' at 10 gpm and 160' at 20 gpm so it would appear either pump would be sufficient with the Betta Flo giving a few more PSI at 20 gpm. So, would one pump be better then the other quality wise or efficiency wise? You said the Myers pump has a floating impeller stack, what about the Betta Flo? Is Betta Flo just another Pentair brand? I looked for information on the Grundfos and the others you mentioned but there doesn't seem to be any online retailers for those brands, or at least when I search all I seem to find are the Pentair brands of pumps.

Ok, the well has been drilled. They went down 265' and it is a 6" casing down 197', static water level is at 46'. The driller said they measured 20 gpm at 120' and recommended to set the pump there. I intend to set the pump on 1.25' IPS 200 PSI poly at around 140' since the pump wire comes in 150' length and I have a 300' roll of the poly pipe. I also plan to use extra long FIP to poly adapters so I can triple clamp the poly pipe. I do not intend to run a torque arrestor as I have heard they can cause a lot of problems if and when the pump needs pulled. I do plan to run a wire spacer or two. This pump will be primarily for household use most of the year plus irrigation of a large garden (1 to 2 acres) and water for our livestock during the summer. As such most of the use will be under 10 gpm but I would like at least 20 gpm when irrigating (2 drip zones at a time at about 10 gpm per zone).  I am looking to set the water pressure at 55-60 PSI for the house and will be using a CSV1W and a 20 gallon bladder tank. Doing the math for household use I am getting a head of about 215 ft H2O (60 PSI= about 150 ft H2O + 50 ft H2O static water level + 15 ft H2O loss in 250 ft of 1.25" poly pipe) (I rounded up to make the math easier and to account for possible variations).  For irrigation it will be primarily drip at a head of 81 ft H2O (10 PSI = about 25 ft H2O + 50 ft H2O static water level + 21 ft H2O loss in 350' of 1.25 poly pipe). So if my math is correct I am looking for a pump that can do around 10 gpm at 215 ft H2O and at least 20 gpm at 80 ft H2O. I may also use a moving sprinkler to water some pasture in future.  I am trying to be energy efficient in my selection (ex. a 1.5 hp pump would meet both needs but would need be throttled back most of the time and thus consuming more energy then necessary) since a large part of the time I will need 10 gpm or less. I understand a 2 pump system would be the most efficient but for now cost constraints are limiting me to a 1 pump system. I am currently looking at a 1 hp Betta Flo pump (BF-2008) or a 1 hp Myers Rustler pump (2NFL102-20-P4). Would one be better then the other?  Is the Betta Flo a floating or fixed stack impeller? Price wise the Betta Flo is a bit more expensive than the Myers Rustler ($409.00 vs $485.00) but if the Betta Flo would be a better pump and more efficient I have no problem spending a bit more up front. I would like to run the smallest hp pump that will work but looking at most pump curves it appears 1 hp would be the smallest that will meet 10 gpm at 215 ft H2O (even the 1/2 hp Betta Flo is capable of more than 20 gpm at 80 ft H2O but appears to max out at 150 ft H2O).
Thank you, Chris

I am in the process of building a house and I am looking for a pump recommendation. The well has not been drilled yet (the drillers around here either charge to much or seem to only drill 1 well a month, the driller I am working with gave a quote of $21 a foot and said there are 2 wells he needs to drill before mine and will take a month to get to). I will be installing the pump and plumbing myself and am just looking to get ideas for now until I have the well drilled. We have a market garden and livestock and are looking to get at least 20 gpm. The wells in the area are between 200' to 300' feet deep with static water levels around 100'. I was originally looking at a Myers Rustler pump like the 2NFL102-20-P4. I am not sure if the Myers pumps use floating impellers or a standard thrust bearing though and I am looking for a pump that would be more efficient at various flow rates when using a cycle stop valve as water demand could vary from 2 gpm when showering to max flow when irrigating. Do you have any suggestions?
