Question about Pentair 3/4hp 115/230v Booster Pump - La01n

1 Answer

Pump is not drive enough water to move the sweeper

The pump is 3 years old and just started having this issue. In the past I disconnected the sweeper and ran the pump to remove air and then it worked fine. But now even that didn't work. The pump is running and sometimes has a strange noise but the noise is not always there.

If the pump ran dry at all and if you had air it very well may have you could have burnt the impeller or it may just be clogged, Remove the 6 bolts holding it together and pull apart, using pliers or vice grips hold the shaft and unscrew the impeller if it looks ok run a curved wire through the veins of the impeller. This should help. If the impeller is clogged their is something getting past the filter and you will need to fix that. Also. don't forget to check your finger screen.

Equator ez2512 combo washer dryer won't go to spin cycle and drain, it fills with water agitates then dial starts clicking around, it stops and fills some more but never spins or drains. What is the f


Check the outlet filter isn't blocked. The machine will only go in to spin if the water level is low enough. So you are left with the outlet pump not working or if you can hear the pump trying to work then you have a blockage. If all this is ok then I might have to suggest that the mechanical controller is goosed (The dial which you say is clicking around). I have taken a few of these to bits in the past. They are not really designed to be repaired (Surprise surprise) but you can repair them if you take your time. They are mainly just a small electric motor which by a series of gears moves a contact plate around to perform the required functions. Good Luck

Shallow water pump keeps stopping


new pump --not big enough for the job
old pump --motor windings problem, faulty start run capacitor
I suspect that as the motor is 1/2 hp if will run good when there is a need for water but under pressure the pressure switch is set to high so the motor overloads and gets hot

Where can I find the specs for an earlier Goodman heat pump?


You say 2 to 3 years... I'm assuming the unit is older than that. Especially being r22. What about the first 10 years??? Normally you will get 400 to 500 sqft per ton of cooling, but, that depends on heat load calculations. If the unit wasn't big enough you would have had this issue 10 years ago, not when the system kept running low on refrigerant. At first guess I would say a 2 ton unit is not big enough but if it worked fine for 10 years...wuth all that in mind, if it were me, (a seasoned professional) I would spend 1800 to fix my 15 year old r22 unit before I spent $4000 on a new r410a piece of junk. Best Wishes!!

Mazda 3 new thermostat, heater works while driving, stops working when idleing


this could be a couple of things 1 would be that all the air didnt get bled out of the coolant system and 2 the blades on the water pump could be wore to a point where as you drive they can move the water around but as the water pump slows(idling) it does have enough to move the coolant. hope this helps

I'am replacing water pump 2006 grand prix,all bolts are remove but one. I can't remove it because theres a wheel pully in the way. I think it's the power steering pump help.


You may have to remove the pump...
BUT , maybe not...
The pump pully has holes in it... with the power steering belt loose or off ... turn the pully to see if the holes will allign with the bolt you are trying to remove... if not... then the power steering pump must be removed to gain access to the last bolt..

Changing a water pump on a 1981 ford f100 pick-up


Ford Pick-Ups/Bronco 1976-1986 Repair Guide Water Pump - REMOVAL & INSTALLATION

6-300 Engines
  1. Drain the cooling system.
CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.
  1. Disconnect the lower radiator hose from the water pump.
  2. Remove the drive belt, fan, fan spacer, fan shroud, if so equipped, and water pump pulley.
  3. Remove the alternator pivot arm from the pump.
  4. Disconnect the heater hose at the water pump.
  5. Remove the water pump.
  6. Before installing the old water pump, clean the gasket mounting surfaces on the pump and on the cylinder block. If a new water pump is being installed, remove the heater hose fitting from the old pump and install it on the new one. Coat the new gaskets with sealer on both sides and install the water pump in the reverse order of removal. Torque the mounting bolts to 14-18 ft. lbs.

  1. Remove the air cleaner.
  2. Remove the bolts securing the fan shroud to the radiator, if so equipped, and position the shroud over the fan.
  3. Disconnect the lower radiator hose, heater hose and by-pass hose at the water pump. Remove the drive belts, fan, fan spacer and pulley. Remove the fan shroud, if so equipped.
  4. Loosen the alternator pivot bolt and the bolt attaching the alternator adjusting arm to the water pump. Remove the power steering pump bracket from the water pump and position it out of the way.
  5. If necessary, remove the air conditioner compressor and bracket. The refrigerant lines should remain connected.
  6. Remove the bolts securing the water pump to the timing chain cover and remove the water pump.
  7. Thoroughly clean the mounting surfaces of all gasket material.
  8. Install the water pump in the reverse order of removal, using a new gasket. Torque the bolts to 15-22 ft. lbs. in the sequence shown.

I have a 300zx non turbo , it is not leaking coolant , electric fan is working good but whene i drive on a hyway , the temperature start going up like 3/4 on the gage, as soon i star driving in the city...


I doubt very seriously the temp problem has anything to do with the timing issue. It sounds more like the water pump is going bad or you have low coolant. When your moving the fan should be free wheeling if it isn't the clutch is bad or the Fan motor is bad. I would look at the Fluid level and water pump for being the issue here.

Loss of antifreeze


Bit odd that mechanics cant find it but here are a few suggestions:
1. A damaged seal on the water pump. As the water in the cooling system is both hot and under pressure when the engine is running, and the pump shaft rotates at high speed, water leaking past a water pump seal will be thrown off the water pump shaft and evaporate very quickly. When the engine is stopped, and the water cools the pressure reduces and so doesnt force the water past the seal, so apears to be okay.
2. A core plug in the engine block has rusted through enough for a very small leak to occour, again when the engine is hot. Core plugs are very often obscured from view by ancilaries such as ignition parts, alternator, exhaust, etc, so are very difficult to see when the engine is running.
3. Rubber hoses can become porous as they get old (10 years is plenty old enough) and as for the two possibilities above, only "leak" when the engine is hot so even a very close visual inspection may not show the leak.
4. If you can smell antifreeze inside the car, particularly when the engine is hot, then you may have a leak on the heater matrix which is like a mini radiator inside your dashboard. If you find the car steams up a lot even on a warm and dry day, this is a good indicator of a leaking heater matrix.

I have personaly fixed "untraceable" water leaks atribuitable all of the above over my years of working on cars. Unlike a proffesional mechanic, time wasnt money for me so I spent many hours finding some of them. Good luck !
