Leaky pump on jetted tub

I have a jetted tub, and we recently noticed a leak when running the jets. The pump is a Hayward self-priming pump, sp-1510-z-1-E, 3/4 HP. It appears to be leaking between the pump motor and the black part bolted onto the motor - where the motor shaft goes in. it drips slowly when the pump isn't on, but squirts water out and sprays it on the surrounding pipes when you turn the motor on. Does the whole thing need replaced, or are there seals I can replace?

You might just need to tighten the bolts. If that doesn't fix it you can dismantle it and replace the O-ring. Be sure to lightly coat the new ring with silicone grease before installing it. A pool supply store should be able to help you with the right part.

Testimonial: "Thanks - tightening the bolts did help a lot, but it looks like I still have a slow leak, so I'll pursue a source for the O-ring. "

A heavy water leak as soon as we turn on the jets. Is it one of the jets leaking or something else?


circ pump and booster pumps are different. circ pump is on during filtration cycles aswell as the heating element. booster pumps run the remaining jets. if you are only losing water when the jets are turned on, then start looking under the tub skirt for leaks within the jets and the plumbing

I have a Mastercraft1/2 HP self priming Shallow well jet water pump, the water fell below the intake in my well and I quickly noticed and turned off the pump. We had water delivered and I'm not su


If water is back up above the intake, it should prime itself in a few minutes. As long as you don't let the case get hot to the touch it should be okay to run dry.

If it fails to prime and pump up pressure, you may have to prime it.

I assume that it pumps from/to the hot tub. If so, the pump is fine. Look for any air leaks in the piping/hoses from the connection in the pool to the inlet of the pump.

I have a jacuzzi tub in my master bath, and it has started surging through the jets in about an 8 second interval. Also I have started noticing a little bit of water leaking from under the side of the tub....


Surging is caused when the pump doesn't have enough water to push to the jets. this is usually a problem caused by air being drawn into the suction of the pump.
take a look at the jet(s) facing the suction cover.
I have seen cases where the water with the air mixed in causing bubbles gets sucked into the suction of the tub and causes the surging because the pump is pulling in too much air.
try rotating the nozzle of the jet facing the suction away from it. point it another way. turn the air control knob closed and see if that is the problem.
the only other issue that could cause this 'surging' problem is a leak in the suction line and could be the source of the water you see under the tub.

Jetted tub is on 2nd floor over kitchen. when jets are on water comes thru kitchen light fixture! Help!


First find access to tub,by code there needs to be access to pump motor,either built into wall or various tubs front skirt is removeable.Fill tub and run to visibly see leak,sounds like bearing assembly gaskets are leaking on pump,could possibly be a jet connection,but if it only does while running its the pump or motor assembly.Hope that helps,in the future make sure water is always above suction intakes or can lead to premature burnout of pump

Hi, Tom, W/D here.
You shouldn't really need a check valve as the foot valve is in effect a check valve.
Next time that you are near the pump when it kicks on and you are using no water, let it achieve full pressure and kick off. Close the discharge valve, isolating the pump and suction line. Watch the pressure gauge. If the pressure falls, you either have a leak in the suction line, possibly a leak at the well head (sucking air), a leak in the casing riser pipe or bad foot valve.
If the pressure holds steady, open the discharge valve and note the pressure. If it falls immediately upon opening the valve, the leak would be on the house side if the pump. Look then for any sources of water usage (ice maker, drips in the tub, water from the pop-off valve at the water heater, etc.).
Best regards, and good luck.
If I can be of any further assistance, please post back.

the pump must not have any air leaks in the suction side of it,, or it will just **** air and not water,,, water is very heavy you see, however i think its the impeller in the pump thats the problem,,,you should try to put water in the out let of the pump so you fill the pump with water first if its dryed out it may just wear out the impeller before it starts to **** water up, if this still dont work turn off the stop **** and strip out the pump to look at the impeller any wear on it and it will need a new one fitted
i hope this has help you, good luck
