    Looking for Informantion about a geothermal failure

    Hi All, I remember seeing a thread about the geothermal system failure at Sherman Hospital in Elgin, IL. I can't seem to find it, I thought it was this site but I could be wrong. Does anyone remember seeing that/can point me in right direction. Thanks

    Filter in Closed Loop System

    The contractor should have said the system is supposed to be clean. If you skip the filter you are putting all your faith on the guys who did the flush, clean, and fill of the system. Also at some point in the future, someone will take the system apart for what ever reason. So I would install...

    125" brass valve question

    Hi All, The more I read on different sites the more confused I get. A standard of the shelf full port 1.25" brass ball valve from any of the big box stores comes with a tag on it that read "600 WOG 150 SWP." I have read that the valve is rated for 600 psi on the net and that seems unlikely to...

    Pump ID help

    I pulled a pump out of wet well yesterday and part of the pump info tag is missing. It was mounted on slid rails about 18' below grade and has a 3" discharge. It looks like a giant sump pump and has a cast housing. The whole this is painted light blue. I was able to get the following info...

    Submersible well motor nuisance trip

    Another note on things overlooked on submersible motors. All of them that I am aware of require class 10 overload protect. Many of the motor starters that are not maded/supplied be the oem miss this detail.

    variable frequency drive

    Assume that you are talking about a submersible well pump, the manufactures require a minimum of 1 minute of run time once the pump has started and they dont like them to be started more than 20 times a day if you are using standard across the line starters. Standard 119 gallon captive air...

    Pump running in SF

    From the onwers manual. ....motors perate with a flow rate of .5ft/sec. in water temps up to 95 F without any derating of horsepwoer." If this motor is running in north America then I would guess the water temp to be in the mid 50's to low 60 F.

    Pump running in SF

    The motor is made in Japan and the fluid end is a Goulds. I believe the problems is with the manufactueres. In the well pump industry every manf. is trying to out do the others by saying that their fluid end can pump more water for a given hp. All the manf. load the motors into the service...

    water well turbidity

    The timer confuses me. Why would you need to "develop" a well that is already in production? Without knowing what the material is, its hard to tell. Did they do a seive test to size the well screen? What type of well casing was used? Have the joints been inspected?

    Earth Currents with Submersible Pumps

    electricpete I freely admit that the math and formulas that you are discussing are about my head. I would suggest that the pump/pump installation is not the problem. I say this because I have worked on hundreds of well pumps from 1/2 hp to 450hp subs and I have only seen this once. This was...

    Earth Currents with Submersible Pumps

    In all of the sebmersible pumps that I have seen. the wire is attached to the outside of the drop pipe and held in place with banning and/or wire.

    Earth Currents with Submersible Pumps

    Is there any other grounds from the building for example attached to the well casing? Also is there rod rods or anoid rods in close proximity to the well casing?
