How to fix a Pentair Water Pump that will not prime?
If your Pentair Water Pump won't prime or retain prime after starting, it could be due to an air leak in the suction line, which would need repair or replacement. Another potential cause is a clogged foot valve or strainer, which should be cleaned or replaced.
Why is the flow rate low on my Pentair HYPRO 9700 Water Pump?
A low flow rate in your Pentair Water Pump can stem from several issues. It could be due to an incorrect speed setting, so check the drive. The piping might be fouled or damaged, requiring cleaning or replacement. A clogged or worn impeller can also restrict flow, so inspect and clean or replace it as needed. Additionally, the discharge line might be restricted or undersized, in which case you should flush out the piping or replace it. Finally, high discharge pressure could be the culprit, so check and reduce it if necessary.
What to do if my Pentair Water Pump runs but there is no fluid?
If your Pentair Water Pump runs but isn't pumping fluid, several factors could be at play. First, check for faulty suction piping and replace if necessary. The pump might be too far from the fluid source, requiring relocation. Ensure the gate valve is open. A clogged strainer or fouled foot valve can also prevent fluid flow, so clean or replace them. Lastly, the discharge height or suction lift might be too great; lower the height or the pump accordingly.
What to do if Pentair HYPRO 9700 Water Pump starts and stops pumping?
If your Pentair Water Pump starts and stops pumping, the issue might be due to a fouled impeller, which needs cleaning. Alternatively, it could be a faulty mechanical seal requiring replacement, a leak in the suction line needing repair, or a leak in the foot valve, which should be repaired or replaced.
Why is liquid dripping from the shaft of my Pentair HYPRO 9700?
If liquid drips from where the shaft enters the pump casing of your Pentair Water Pump when it's full, it's likely due to a damaged mechanical seal. You will need to replace it.
How to reduce excessive noise from my Pentair HYPRO 9700?
Excessive noise from your Pentair Water Pump during operation can be caused by several factors. First, ensure the pump is securely fastened to a firm foundation. Next, check that the piping is properly supported to relieve any strain on the pump assembly; make necessary adjustments. A restricted suction line can also cause noise, so clean or correct it. Finally, cavitation may be occurring; try reducing the speed, increasing the inlet size, or using a thinner material.
