I bought a 1970 house in May and found the well pump to operate fine, except it has a drip in the pump housing. I eventually realized that drip must have been there for some time as sections of the flooring had rotted. So I am replacing the pump but am new to wells and after looking at the instructions that came with the new pump, decided to look for help.
I have a meyers 1/2 HP pump in my utility room. There are two black polyethylene pipes coming up from the crawl space. I told the guy at Lowes I have a two pipe system and he said to get the convertible pump. The pump I bought is 1 HP
http://www.lowes.com/pd_78551-15649-PPDWJ100_0_?productId=3223763&Ntt=well+pump&Ntk=i_products&pl=1¤tURL=/pl__0__s?Ntk=i_products$rpp=15$No=15$Ntt=well%20pump$identifier=
My question deals with the ejector. The pump came with the long venturi for the deep well and from the diagrams it shows the venturi to be placed in the well casing. I am uncomfortable opening the well to change anything down there. I thought I would just connect the two pipes to the pump just as they are on my current pump.
So is there already a venturi and ejector down in the well? Is the venturi specific to the pump being used or can I use the system already in place?

Unless you are a high adventure type of personality, I highly recommend not messing with the in well parts.
Yes the venturi is specific to certain pumps, water levels and pressures.
Since you bought a Lowes pump, if it says 1hp, you can pretty much assume it's comparable to a good 1/2 or 3/4hp pump of a good name brand pump.
The venturi varies in size with the depth to water, the horsepower of the pump and the number of impellers in the pump.
I would think that you can expect about the same flow and pressure that your old pump gave you, but by buying a 1hp from a big box store, I wouldn't expect any improvement at all.

Thanks for the help. I definitely don't want this project to turn into an adventure 
From what I am able to gather using the old venturi and ejector will let me pump water with this new pump just not as well as it could. I am willing to live with that. |

You didn't say where you are in Michigan. I'm from there originally and might be real familiar with your area.

I lived in Union Lake and Milford, so I put a lot of systems in your area. You do have a screen for sure and it probably could use an acid treat. Just be sure to ask around who is a good guy to hire. I've been away too long to know who's even in the business anymore.

| I am having problems with my well also, I have replaced everything from the tank to the foot valve. I also have a pump from lowes, I initially bought a 1hp and the plumber told me it was to large for my system. So I bought a 1/2hp and now the pressure will will not get to above 39lbs. The pipes to the well are 1 1/4 supply and 1 return. The pump that came out was a 1/2 Goulds, if I go up to the 1hp from lowes will that also increase my pressure? I acutally lowered the cutoff swithc to 38lbs to have the pump cycle properly. Other than the pressure it all works fine. Any help would be great. Thanks Richard |

We see this problem on here all the time. Those Lowe's pumps are just plain not up to snuff. It isn't half the pump that the Goulds is. Also you should never listen to a plumber in regards to well stuff, it's not their field and they don't give good advice.
My advice is to replace it with another Goulds, you won't regret it. |

While on vacation in Michigan (Clarkston/Waterford area) I looked through the phone book for Well Drillers. Many of the old guys I remember are still in business. The two I would recommend would be Ward and sons and Ray LaLone.

Your welcome.
I had a look at your link. That's not a real Myers pump, its a Chinese knockoff of an Italian pump and it's junk.

Hey, what does a Gould's pump or other recommended pump have that a Myers Flotec or Wayne doesn't? I am understand you get what you pay for but what would the differences really be? A 1HP motor is a 1 HP motor as far as I can tell, but I am starting to be the go to guy around my woods for pumps...thankless job as you all know. |

They aren't built as well, not just the motors.. heads too. put a flotec or utilitech beside a goulds or comparable pump and there is no comparison. Hook them up and run both, again, no comparison. Kinda like buying your kid one of those knockoff atv's instead of a Honda. Sure they work (sometimes), but never as good, and NEVER as long...
1hp is a 1hp? Thats like saying a screwdriver is a screwdriver.. With moderate use, cheapo Phillips head might last you a month or so but I have a couple kleins that I've had for years. U can be the guy that installs pumps and tanks that last a year or so, or u can be the guy that installs pumps and tanks that last ten years... all in who you wanna be I guess. |

Motors have service factors. When the service factor is multiplied by the horsepower, you get the true horsepower. All the big box store motors are unity, 1.0 instead of 1.24, 1.4 or 1.65SF. So when you buy a good pump that is called a one horse, you may actually have a 1.5hp pump. Also, the windings are better in a good motor, they are made to last longer. The motor shafts on a good motor are stainless, regular steel on a cheap motor. Then there are the bearings. On a good motor, you get ball bearings that are factory greased. On a cheap motor you may get only one ball and one bushing or maybe just two bushings. These are not repairable like the good motors.
Basically all the things you can't see are cheapened. You will also notice that the cheap motors have more and larger cooling holes in them. This is because they cut back on the amount of wire in the windings, so cooling becomes more critical.
Give an Engineer a few days with anything and he can figure out many ways to make it cheaper and how to make it die sooner.
