View Full Version : The  water  pressure drop  in  the  house

Dear  Sirs!
We  are  a little bit over  a  year  in this  house and  last  summer  we've  never  experienced  the  water  disappeared  at  all after  hosing (watering ) our  large  8,000sq ft lawn using  two hoses  connections for  about  an hour . 
So  the problem  is  that  after  an hour  of  continuous  water  sprinkling  the  pressure  drops  to zero  and  after  that  we  are  waiting  for  1-1.5 hour  till it  comes  back again to 40-50psi .It  never  happened  1  year ago  .This  is  a  drilled  well and  the  cut in and off  pressure  I  have  adjusted  8-10 months  ago  .I  don't  remember what kind  of  pressure  tank we have but  it's  an oval vertical tank  with a  pump  mounted  in it .
Do I  simply have  to  readjust  the cut in -off pressures  again or  there  is more serious  thing  to look  at ?
Thank  you  in advance 
Denis , Nova Scotia, Canada

Next time that happens, pull the grey cover off the switch and see if the points are open or closed. They should be closed. If they are, then see if the pump is running. 
 
Sounds like you are simply running out of water and the well takes that hour to recover. 
 
Is your pump in the well or above ground?

That's a lot of water to supply. Sounds like you are running the well dry since it recharges.

Hi  , thanks  a lot  for  response . I  am  not  able  to  see  the  points  right  now  as  well  as  a  pump  because  it's  probably  in the  well  . But  today  my wife  said  she was  watering  for about  30-40 minutes  and the  pressure stayed the same  and  the  water  didn't  disappear  this  time .
Some one told  me  that  may be  I will have  to  drill  a  deeper  same  well .Can  it  be  the problem  of  a  shallow well ?
Thanks

Sure, deeper wells can extract more water. You mentioned a drilled well but didn't say how big or how deep. My house well is 6" and 200' deep.

Stillwater, it might be possible to lower your pump/wellpipe a little lower in your well and do better with water. Sounds like you need to get a well pro out and get his opinion.

I  called  several  local  plumbers  , there  was  no  any suggestions  to  lower  the well  pipe  or  a  pump  .Just  drilling deeper. Probably  as  I know  there  is  a  foot  v/v  on the  very  end  of the  well  pipe  .Lowering it  deeper will  course the  mud  from the  bottom  to come up  with  water , right ? 
Guys  , what  do you  think  ,to install  the  bigger pressure tank  will rectify  the  problem ? Or  I  still need to  look  for  somewhere between the  well  and  the  pressure  tank ?
Thanks

What kind of pump do you have.  Submersible or with a foot valve?

I'm  not  sure  , I  don't  have  any  documents  for  this . The  pump  breaker  is  in  a  furnace  room and electric  cords  are  running  from the  breaker  to  the  small  control  switch  where  we  adjust  cut in &  off . Yes  , you  are  right , I need to find  out  first  what  and  where  the pump is .

an oval vertical tank with a pump mounted in it 
 
How many pipes going down the well. 
 
Sounds like a fairly shallow well and fairly small pump.
 
 
Sprinklers on two hoses are probably putting out about 5 gallons a minutes.  That's 300 gallons an hour.   Pretty good for a shallow residential well.
 
A larger tank won't help.  Whether you can lower the well pipe and whether it will help all depends on the water level in the well and how far the present pipe extends below the water level.  Chances are it won't help much.
 
How dry has it been in Nova Scotia lately.  Sounds like the water table was higher last year.

Yes  , this  summer  as  well  as  spring  is  very  dry  , extremely  dry . We  have  
35 degrees  Celsius (95 F )  in opened  areas. Can  this  wave  of  heat  be  the  problem  of  the  dry  running well ?

Yes, water table not only drops during hot, dry weather but people use more water causing it to drop more.
 
Try watering lawn for shorter periods, giving well time to recover.  Or just one hose.

A larger pressure tank will not solve your problem.
 
The pump is either in the well or above ground. If it was above ground, then you would see it either in a basement, a utility room, or outside in a contained pump house.

Thanks  a lot  for  help , for the  present  time  the  water  table  seems  like has stabilized , we had  some  periods  of rains  and  there  was  no  water  pressure interruptions...
