WaterFurnace Needs Increased Flow

Our geothermal WaterFurnace's "water flow" LED has been illuminating. I know, based on prior testing , that our well pump produces slightly more than the max 5 GPM the WF requires on its high level, i.e., pump fills a 5 gallon pail in 55 seconds. But, if other water uses such as filling the washing machine and a shower, occur while the WF is running on high, we lack sufficient water flow.

I won a well pump on eBay. Our current 1/2 HP 7 GPM WP was installed in 2002 when initial WP, circa 1983, was pipped by lightning. The WP I won is 1 HP 7 GPM with 10 GPM max depending on head in well, no question it is much heavier. Arrived yesterday very late in day, UPS drivers workin' overtime, too late to schedule wellman to swap it in. Must wait until Monday.

This is not to be aother FE DIY project although, with enough help, I could pull the pump hand-over-hand. Wellman has a motorized device that does it much easier. But, even if I pulled the existing pump, no way wiould I intend to screw up the wiring and the attachment of the new WP to the pipe. In addition to more HP, new WP has bigger outlet and that must be stepped down to pipe.

There's a ring on each WP to attach a cable and neither the initial or the existing WP has had a cable attached, the pipe has been the lone attachment. Since we'll have a bigger exposure to the more powerful WP torquing itself off the connection to the pipe, it will be cabled. I'd feel real stupid to end up with it at the bottom of our 250' drilling.

I'll continue this post when the wellman visits.
