I have a new 22k gallon in-ground vinyl pool. Pool has a Paramount in-floor cleaner which required a pump that could pump about 60 gpm at 70ft of head (according to Paramount tech support). Initially, the pool had a Jandy Flo-Pro 1hp pump but the in-floor cleaner was not performing well hence the call to Paramount tech support. As a result of their input, the PB replaced the Flo Pro pump with a Jandy Stealth 1hp full rated pump for better performance. The pump was hooked up today and it looks like something is definitely amiss with the new pump. The new pump seems unable to prime and after about 5-10 minutes it overheats and cuts off.
Pool equipment consists of the following... Jandy Stealth 1hp full rated pump, Jandy CS-150 150sq ft cartridge filter, Jandy LXi 250k BTU heater, Paramount Vanquish (PC2000 equivalent for vinyl) in-floor cleaning system with deck-side debris canister.
The PB is going to contact Jandy tech support in the morning but I thought I'd check with the experts and see what you think. The PB suspected a problem with the electrical service to the pump so we met the electrician and he checked everything and claims nothing is wrong with the electrical supply or connections. He said he sees a constant 120 volts and a max draw of 12 amps. The pump is on a dedicated 20 amp 120v circuit.
We are puzzled as to why the pump seems to not want to prime and overheats. PB tried removing the Paramount valve and filter cartridge to remove any possible restriction and the pump still has about an inch of air in the top of the basket. We don't see any air coming out of the floor pop-ups or wall returns.
Here is a photo of how the pool equipment is connected. The PVC valves on the suction side are for the skimmer and the main drain/debris canister.
Any suggestions? PB is contacting Jandy tech support tomorrow but I figured there are many experts here that may offer suggestions.
