What to do if my Allweiler SPF is not pumping?
If your Allweiler Water Pump isn't pumping, several factors could be at play. Start by checking for transport screw plugs and remove them if present. Then, verify that the supply or suction pipe isn't blocked by any fittings; if it is, open the fitting. Ensure the supply or suction pipe is fully bled and filled. Air pockets can also cause issues, so install a fitting for bleeding and correct the piping layout. Also, make sure the pressure pipe isn't blocked, and that the pump isn't running in the wrong direction. Lastly, check if the pump, supply/suction pipe, or suction strainer are blocked or encrusted, and clean them if necessary. Also, ensure that air isn't being sucked in, and check for excessive gas causing cavitation; if so, inspect the cable gland, clean/enlarge the filter, and enl...
Why is the pumping pressure dropping in my Allweiler Water Pump?
If the pumping pressure of your Allweiler Water Pump drops, several factors could be responsible. A worn-out spring or leaky valve seat can cause pressure drops, so you might need to install a new spring or valve cone. High spring tension can also be a factor; relieve the pressure by turning the adjusting screw and then reset the pressure relief valve. Foreign particles in the valve can obstruct its function, necessitating removal and cleaning of the pressure relief valve. Additionally, if the spring has insufficient tension, resetting the pressure relief valve may resolve the issue. If the valve seat is leaking, rework or replace the valve cone or valve casing. Lastly, if the pressure relief valve rattles, measure the excess pressure with the fitting on the pressure side closed, then rese...
