Pumps, Wells, Tanks, Controls / Re: Need Advice on Setup for a Resto in the Philippines

thanks Cary. I am waiting for the driller to find a way to get the sand out. The sand is only 10 feet at the bottom - I apparently misunderstood my Filipino workers. I will also follow your advice regarding the PVC pipes - the issue is that that I never saw anything else here than the Sched 40 pipes - here in the Philippines you can only dream of buying threaded sch 80 with metal couplings, or 125-160# black poly pipes ... :-) ... I might get PPR pipes but I need to go to a bigger town to get the 1 1/4 Inch variant. I am still searching. I will set the pump higher next time and I will valve off the flow to about 12 - 15 GPM ... 12 GPM is the target value for connecting to the house - I have 3 10x54" Pentair Filters with Fleck valves which anyhow can only process 12 GPM. Probably I just was too excited to watch the 25 GPM flow ... I admit it is fascinating :-) ...

Well I am not really doing good .... I feel like being in the wrong movie here. Let me tell you what happened. We installed the submersible pump at about 55 feet (of 70) and let it run. It sucked a lot of sand in the beginning but slowly improved. It ran for 3 hours providing the yield at the maximum of the Goulds / Franklin pump of 25 GPM ... I thought I am in water heaven but then it happened ... the pump fell down a couple of feet because the pipe was not correctly fixed. Good luck we used a rope so we could get it out again. Because of the weekend I could not buy new PVC pipes and so we could only start another try today. The outcome of today was that apparently the well is almost halfway filled with very fine sand - no way to place a pump.

What they are suggesting now is to get the well driller here again to fix the issue. I have some doubts that this will ever work but I am far from being an expert. They might be successful to get the sand out but my fear is that even when I put the pump higher we will run into the same problem again. The big question is whether there is a feasible way to fix the situation or do I have to drill well number 5 with every measure taken to avoid sand take in. Note as it is common here there is no gravel pack at the bottom and the sand is really very very fine.

  ... sorry did not see your post earlier. And yes I was on this worst forum ever :-) ... I did not know that I could ask these questions as well here. Anyhow the well is done since yesterday and the yield seems to be very promising. Btw. - I have now 2 CSV's - the first took very long for delivery and Amazon gave me a refund but it subsequently arrived and the second CSV I ordered here on this site together with a cycle sensor.

Because all my water knowledge is pure theory from reading I welcome any type of help from people with experience. Here in the Philippines the experience is quite a challenge - if somebody ever touched a PVC water pipe here he immediately calls himself a plumber.

So let me summarize what I am gonna do now:

1. Install the submersible pump - a Goulds GS2515 with a 1.5 HP Franklin Motor plus Control Box.
2. My approach is to settle the pump at about 1.5 meter above the well screen at the bottom.
3. The well is 70 feet deep and the static water level is at about 15 feet.
4. I intend to acquire a Varem pressure tank (that's what they have here) of 20 liters (5.3 Gallons).
5. My thinking is to have the pressure tank at 55/75 and the CSV at 65. Because the filtration system after the pressure tank will consume about 15 PSI I will still get 50 in the house with a short low of 40 when the pressure tank is at its cut on point.
6. At last I will install a whole house water filtration system and then connect the house.

Interesting or better challenging will be to set the pressure switch and the CSV - I never did that of course and I am sure my "plumber" here did not do it yet either. Also interesting will be the discovery of new leaks :-) after the pressure got up from a max of 40 now to a max of 60 / 50 in the house with the new system. I intend to use PVC pipes everywhere (unless I get an advice to use PPR) - I will use 11/4 Inch from pump to pressure tank, 1 Inch from pressure tank to house and 3/4 inch to the individual consumers. Given your recommendation I will not install an additional check valve before the pressure tank - the Goulds has an internal check valve.

Of course I am happy with any advice :-) ... thanks anyhow.

I am a Swiss living here in the Philippines and about to open a Resto/Bar. I have built yet another well which will be 70 feet deep with a 6 Inch PVC casing. I have a Goulds 25GS15 (25 is the max GPM and 15 = 1.5 HP) with a Franklin Motor and I have ordered a CSV1A. My estimated water consumption would be about 1000 Gallons per day but this could become more. I live in the province of the Philippines and there is no chance to find anybody knowledgeable about the whole setup of a water system - a plumber here is somebody who knows how to join PVC pipes but you have to provide the design. If not they might do very interesting things :-) ....

My hope is that the yield from the well is sufficient to build the system without intermediate storage tanks. The loss of PSI due to the filters will be about 15 and so I would like the valve PSI setting as high as reasonable. Let's state 45 PSI as the minimum after the filters.

And here my questions:

1) I tried to use the "Minimum Pump Run Time Calculator" to figure out the size of the pressure tank that I need but I am not so sure whether I use it correctly.  The values I entered are 0.7 GPM (is this right? I just divided the 1000 Gallons by 24 * 60 minutes), 70 Valve Setting and 60/80 for the pressure tank.  The result would be a 32 Gallon tank ... a fool with a tool. So I really would need advice on the size / specs of the pressure tank that I have to look for.

2) Would you recommend to me to get the Cycle Sensor Pump Monitor in this setup?

3) Maybe this is a stupid question but I have to ask it :-) ... do I need a check valve anywhere between the submersible pump and the CSV?

4) Any other advice is welcomed ... maybe everything is wrong what I am trying to do.

I am an IT person and far from being knowledgeable about water systems. But after my experience here with my first well built by drillers and plumbers here (diameter 1 3/4 Inch with no screen, 70 feet and a screaming jet pump - all with a very low yield) I was forced to google and read. 

Any help is more than appreciated ... thanks in advance.
