Seeking help with new pool- sand filter works barly for short time and no pressure

[tallguyy808]

thanks for the quick reply...im doing searches like crazy on this form using the google search link in your sig trying to find reasons for whats happening.
I hear you....im close to screaming at namco. they wouldnt return our call last night either so i had to go over there after work to get the part. The pool installers...each day we have called them...and they were namco recommended =(. We paid them cash...so its not like we can do anything there.
I am just not sure who is the blame really..the installers or namco. we had lots of bad timing with the hole build..the water came hours late...and the electrician was delayed so we really coudlnt test anything while the installers were here. sigh

I'm not at all familiar with your gear so these are general suggestions.
Is the outlet from the pool (skimmer) clear of obstruction?
Is the return to the pool (eyeball) clear?
Did you read in the manual that you shut off the pump before moving the multiport valve?
What happens with the multiport in Recirc? Backwash? Rinse?
Are there any other valves in the lines? Are they all open?

thanks for the reply dave.
Not sure what you mean by eyeball. the hoses all have water in them. the skimmer part on the pump itself has water in it..but when running i dont think has enough..and it has moister in it.
if i run in backwash or rinse...water comes out of the pump. i do turn it off each time when sitching modes. after doing that i will get water coming into the pool for a very short time.

i see no obstructions anyplace.

I went to namco today and they said electric could not have enough power. which is also a new trenched run. i will put an adapter on tonight and try from a different socket.
Namco said only thing they can do at this point for me is swap pumps. so i will probably be taking it off tonight if the electric doesnt fix it.
The installers said they can come look in a few days also

When you say "water comes out of the pump" do you mean water comes out of the waste port on the multiport valve?

Does your multiport have a recirculate setting? What happens with that.

Is air getting sucked in through your skimmer into the pump strainer pot (pump skimmer)?
Is air leaking into the pump strainer through the lid?
Is air leaking into the suction line at a fitting?

You can test for suction leaks by smearing some shaving cream onto the suspected joints and watching to see if it gets sucked in.

A 1 HP pump should be plenty for your pool--I have a 1 HP pump on my 18 x 36 IG and it works just fine.

When you turn the pump on, are you making sure that there is sufficient water level in the pool? Does the pump ever prime?

[tallguyy808]

i dont know if air is seeping in. ill try the shaving cream trick.
I took the pump off and brought it to namco last night. they just put it to power and ran a hose to it and said it was fine.
i hooked it up and i swear its worse. he told me to put it in bypass to pool mode ...and it didnt help. ill get no pressure on the guage still..and it will only shoot into the pool a hair...then after awhile you it will make gurgling noise...and it will push lots of water into the pull and suck at the pool skimmer like crazy for a short time then stop completly...then it wont push water at all. i even took the cap off the motor skimmer...and unlike before...now water just sits there. its full...then after time water will start rising......if i leave it open after a lilttle bit wham! it will suck the water in and push it into the pool for a short time...then nothing all over again. it still seems like a pump to me. no?
