here's the update..no leaks... just letting the pressure stay high and back washing not as often... the higher pressure stops the pump noise!

OK Folks here we go... after a week of lots of rain and other challenges I'm back here to give ya'll an update. Last Saturday I used some dish soap to try to find the leak..no help... I was tired of hearing the pump struggle so I turned on the water to prime the pump...that night it rained...

Dave, I noticed a leak at a joint, but it is after the filter on the return side to the pool. dont think that is the problem, but it is on the "to do list".

OK fellas... I think I have my marching orders for the weekend... Let's all hope and pray that my next post will be one of excitement of solving the problem!

Checking the line between the pump and pool strainer is a lkittle hard to since it is buried. Is there a method to check joints (like using soapy water on a gas joint) to check for the suction leak? there are very few joint I can check without digging up the line and busting out a patio slab.

Bama..yes when i turn on the primer water valve (adding water to the pump) the pressure dies go up.

Here is the latest.... Plummer just left the house... He ran a professional snake between the pool strainer and pump... no obstructions... after watching the pump operate, his diagonsis is pump cavatation caused by a possible impeller problem..since I have already checked the impeller for...

Thanks John, I'm actually goiong to call a local plumber and have him snake out the line between the pump and pool. I used a do it your self snakeand a high pressure bulb on th end of a hose but it didnt help. I'll keep ya'll posted. another question... could the DE Im using to charge the...

pump strainer basket is full of water but looks like foam at the top of it??? I have a water primer valve that I can use to add water to the pump if needed at start up and when I turn the water on the pump struggles less and the pressure rises to 8 psi.

OK FOlks.... :wave: plugs tefloned! strainer weir fully operational, pool water level good, pump strainer sealing properly.... Yet still no pressure... ( 2 - 4 lbs) operating pressure 12 psi Additional info: When I installed the new valve for the Pentair 48 DE filter, the intake for the...

OK here's the up date... water level good, skimmer not closed or preventing proper water supply ( i've been there before), I did apply a silicone grease to the O ring at the pump skimmer lid, no improvement. I think I will order a new O ring and see if that solves the problem (local supply did...

ok I cracked open the pump..no clogged impeller... pump striner is full of water...but it has bubbles in the top of it..all most like a foam?!? and I have noticed that there is more air bubble coming from the outlet jets in the pool. looks like it might be sucking air?

:rant: OK Folks...HELP!!!! everything has been running smoothly for a week or so..and now I have NO pressure in the filter. I heard the pump making a struggling sound and checked it... water is flowing and circulating. the pressure was at 12 psi and has gradually dropped to nothing. I have...

and BTW... is there a formula for what size/btu to purchase?

I am located in west central Texas. Have thought about solar... however.. I have lots of trees on the south side of my property and by 3 pm the pool is in the shade. last year was the hottest summer on record in a long time and the water barley got to 80 degrees. Because of that, we never use...

I am looking at buying a Sta-Rite Max-E-Therm Low NOx Pool and Spa Heater Nat gas 400,000 btu. any opinions? :!:

My wife wants me to install (for lack of a better description) a continious flow/current system in our existing pool to allow her to swim against the current (like the ones they advertise on tv). I have googled trying to find just the pump or device that will do this, but with no luck. Any...

UPDATE: The diagonisis was as follows. My ten year old pool safety cover had started to disenegrate and small parts of the fiber had clogged my grids over and ovber again. after the final cleaning of the grids and multiple back washes and filter rechargeing as well as strainer filter socks...

no DE discharge back into the pool

one other thing i THOUGHT OF... when i opened the filter Saturday.. there was quite a bit of DE on top of the power head... and the grids were muddy looking. and I did not acid wash, but power washed them and the power head and all internal parts. check flow by opening valve to filter and...

ok.. I have backwashed over and over again... still experiencing the same high pressure. Checked plumbing again..its all correct. my pool is still a lovely green... so here is what I have deducted from all the advise... I will crack open the filter housing again. clean grids with power...

yes backwash water comes out of the backwash pipe. Also If vavle is set to "recirculate" bypassing filter the pressue is zero (which it should be) correct?

it was the pentair valve for the Pentair DE48 1 1/2". yes the pressure goes to zero when pump is off. The pressure was 12 psi after the disassembly and cleaning of the grids. I'll recheck plumbing when i get home in about 30 mins.

When replummed after the new valve install, I also added about 5' of new 1/1/2 line to accomadate a pool heater in the future.

Past "clean" pressure is 12 PSI

Yes grids cleaned as specified. water is very dirty due to start up... I realize that is what is clogging the filter grids, however I cannot backwash the grids..all the water expelled is clear. the psi during backwash is around 30 psi. not sure if that is normal. I did recharge the gridw...

Last summer I replaced the fiber filters and pump head in my Pentair DE48 filter. It was allowing DE to seep backinto the pool so I have now replaced the filter valve. It is a 1/1/2 inch system. I also had my pump rebuilt last summer when it dry seized. The issue I am now facing is an...
