I will double check tonight. Def not out the backwash pipe and I never turned any other valve. I can see water going into the filter. Surely if I had a blockage in the return my pressure would go passed 30 PSI ?

Guys, I just bought a new Hayward EC75a. The filter is pumping water into the filter but the return never goes back into the pool. My PSI is around 30 so I am stumped on what the issue is. From my limited knowledge I am guessing I have an air leak on the return side of the filter ?

thank you ALL. I am going to buy one from Amazon or new from ebay and try and fit myself. Cannot imagine its that difficult. :rolleyes:

Not sure how old it is to be honest. I turned it off since the pressure was at 40 PSI , bumped it and turned it back on.

Sigh, the pressure got too high on my Hayward ec75a filter and burst on the side. :( Is there anyway of repairing this ? Dropping a grand on a new one doesnt sound like my idea of a plan. thanks !

guys, I am looking to supplement the tablets I am using in my 17000 gallon pool. I am using liquid chlorine with is 12.5% sodium H/C. I am wondering if a 1lb packet of shock containing 68% calcium H/C is cheaper/ more conventient and will add more chlorine to my pool. I think 1 packet would...

Its threaded . Thank you Sir. How do should I wait before starting the pump ?

Hi Guys, Basic question I think but I am not sure of the difference. I had to replace a ball valve and now when I turn on the pump the pressure in the pipe by the ball valve causes the pipe to seperate and spew water. Question. Do I need pipe sealer or the cement ?

I actually just saw this thread http://www.poolforum.com/pf2/showthread ... won-t-work I will try and check that tomorrow .

Sorry, I should have added more detail. Its through the skimmer and was working. It did not come with a suction gauge. Thanks for the reply

hi Guys, i have searched around and so far not been able to resolve the issue. My kreepy is a couple of weeks old but is not moving. I have checked nothing is caught in the hoses. Any other ideas ? Its still pumping water through the pump so I am a little confused. Also , I have noticed its...

So a quick update , if anyone has any ideas please let me know. I would love to be able to save a call out fee and repair. If I look in the basket and turn the pump on I cannot see any water coming in from the pool. If I put the hose into the basket eventually water comes seeping out of the...

hi, The pump is above the water level. No flow when the pump is on. If I take the cover off the basket it is full. When I turned the pump on the water drains but the basket stays empty. Once I turn the pump off the water seems to come back into the basket. I assume this is from the line...

Hi Guys, So I bought a house a month ago and already I am in at the deep end with my pool. I have an inground pool with a Hayward ec75a filter. I returned home today to find my water level below the skimmer. Once I filled it above the skimmer line I turned my pump on to find that it was not...

Sorry, yes I am using the aquachek 7way strips. I just moved into this house so and I inherited the chemicals the owner had used. I did not see any calcium hardening chemicals. Its quite possible my hardness is way off ?

hi, thank you for replying. I think I found most of my answers from this site. What a great new resource. I think from the calculator that i need to add 20lbs of calcium . Does this sound right ? I know its a pebbletech surface.

Guys, Could I get some pointers on the results of my aquachek chemical test. I need to know what to buy and how to use of each. Thank you in advance Total Hardness 100ppm should be min 250 PH 7.2 needs raising slightly Alkalidity 60ppm should be minimum 80 Cyanuric Acid 20ppm should be min 30
