today we're gonna talk about water pumps
our water pump has died three times
the first two times it was in the first like six months
then i figured it out and now this time i was checking the water pump and i broke it
I broke this little piece
so now we have to change it
and the other two water pumps that i have they stopped working because of the switch
it's a very very common problem that the water pumps have
so the switch looks something like this
we have this one which is the one that broke off
this one the switch stopped working
which is very common so today we're gonna be installing a water well pump switch
these things will last forever
we're gonna be installing that plus uh a pressure meter
so we can regulate the pressure with that well water pump switch
the switches that the water pumps bring originally they're pretty weak and fragile
so they can stop working at any time
or let's say your water tank it's empty and you leave it on they can burn out real quick like in an hour or maybe less
so yeah that might be a reason why ours stopped working the first six months
i have another problem which i think our water pump is
getting some air from somewhere so we might have we might have a leak
so i'm gonna be installing first the switch with the pressure gauge we're gonna turn it on see how it works
and we can find out if we have a leak or if we don't have a leak
i'm gonna try to film as much as i can so i can show you guys
so we're gonna be using this one, the euro pump
this one says it's 12 volts 6 amps 40 psi so the flow is 17 liters
and the one we were using was 15 liters per minute
which i think it's almost the same and but this one was 55 psi
so that matters because you have to also adjust your pressure tank
which we did last time when we changed to this one
we have we adjusted the pressure tank it's a little tank i'll show you guys
and you could just pump air into it or release some air and you gotta see what's your low cutoff pressure
so with this one we get water through here and it comes out through here
through this hole
so the idea is to put the switch after it comes out so switch we're gonna put it like this
and then
we put in the switch right here and then the meter
or we should do the meter and then the switch
yes
so we're gonna do it like this
we have this setup water goes comes out of the pump
to the psi then it comes to a switch and then it goes out to whatever it needs to go
is it has four terminals
the two center ones are the motor ones
so we got
positive negative
and this is going to be positive from the boat negative from the boat
pretty simple if you have grounds you connect the ground
ground for from the pump ground from the from the boat
but we don't have our ground we only have a positive and negative since it's a 12 volt
i don't know if it's gonna work since this is made for a house but we're gonna try it out
we were told this by another cruiser that he has been cruising for a long time
so that's what why we're gonna go with this and why we're not gonna replace the switch
on this Jabsco
and we're gonna leave that one as a spare just in case this one doesn't work
these are two small this ones are like 16 gauge and i think the wire
is a little bit thicker so we're gonna go with the blue ones let's see if they work
they do work so we're gonna go with this ones
they're a little bit more big
we're going with blue ones
okay so now we're gonna measure the distance for the cables
all right good
we got the negative cable but the negative negative cable doesn't
reach so we're going to extend it with these little piece
okay guys so now we have the negative cable we did a little extension which which we can connect here
and the positive here or i mean positive on the left side
negative on the right side
negative positive
and this is gonna be positive from the boat negative from the boat
okay now i'm gonna go put the pump in the location connect everything turn it on see what happens
okay guys so i installed the water pump it goes right there
there's gonna be a negative
to the boat
and positive
i'm done doing this the installation i'm gonna show you how it's connected so you guys could
do it in your boat too
we got the water pump right here so it comes from the water tanks
through a hose right boom
small strainer to the water pump
then we got the pressure gauge
and then the pressure switch
so this is how it's connected so the two middle ones
this one and that one are
one is for pump for the motor positive motor negative so
this one right here motor positive
motor negative and then we got
from the 12 volts
we got 12 volt positive 12 volt negative
so it's 40 psi and when it gets down to 20 psi it turns on
most of you guys that have water pump issues
that is like 90% of the time it's gonna be a switch so now you have a solution
pretty easy to do just take a couple of minutes hours it depends on the space you gotta work in cables
i might put a little bit more pressure i might put it up to like 45 psi instead of 40
so it takes more time to turn on the pump so it's not every time you turn on
like it takes a while for the pump to turn on after we open up like the
the sink or the shower
but we want a little bit more pressure
not too much pressure because a hose can pop or something or a connection
but we're gonna go between 45 and then 20 at low pressure
so if you turn on the water and your pumps runs like right away
that means your pressure tank it might be off or your pressure switch is gonna soon be dead
so you might wanna just like when you turn on the water hear the pump
it takes a few seconds for the pump to turn on and then turn off
turn on turn off
and if your pump stops working try to disconnect the switch and connect it to 12 volt power
see if the motor is working don't throw it away you can just fix it real like cheap for like 20 dollars
you could make this setup so yeah don't throw it away or just give it to someone that that's willing to reuse it
because i mean usually a switch is like 40 to 60
and a brand new pump it's gonna cost you eighty dollars
so inside the case of the well water pump which is this one
there's the specifications so you can see it says the cutting pressure
so on in is 20 psi
and off out will be 40 psi
i will also put all the pieces that you need in the description
so you can just buy everything and put it together
okay so i'm gonna uh show you how you could know if your
switch is it's not working and you can just test the motor on your pump
so i'm gonna show you how you can connect it
so you have two cables coming out of the switch
one goes to the positive power 12 volts and from the back you got the negative and positive positive goes to a switch
then here boom
so what you want to do is take this cable and you could cut it or open up the switch and disconnect it from the switch
and just make sure that when you're going to connect the motor you have both cables positive and negative coming out of the motor
and connect that to your
12 volt supply
and it should turn on if it doesn't turn on then you have a bad pump
if the switch goes bad and your pump is like on like for hours
your motor might burn out so you might have to buy a new one
and this one goes to a sensor which it turns on a light when your water pump is on or off
many boats have it some don't so if you don't have it you can just take it off
and seal it
thank you guys for watching it's been a pleasure
we're enjoying the bahamas right now
and it's a mess that's how i leave the boat once i'm done working
pieces everywhere tools
everywhere
now i have to pick up everything and so
now we know we got a pump working and that's it
you
