I have a poolpump that is old, super loud and sucking tons of air from somewhere. I have been planning on replacing it for a while but now, from what I gathered, the air leak on the suction side has become so bad that the filter pushes all the dirty water back into the pool (actually spa) once the pump shuts off (I did the valve test and tons of air is hissing for quite a while until water starts coming out).
On top of that now the filter started leaking too despite a new o-ring (Is it possible to overtighten it? I feel like it has gotten worse since the last cleaning).
From what I have learned reading around the forum here both my pump and the filter are in theory undersized for my pool am I right? I have never really had any problems with the clarity of the water/algae even though I am rarely ever testing the water (bringing it to my pool store like 4 times out of the year) and just add the chemicals by 'feel'. Like I said it has worked great but now that my wife is expecting (any day) I wanna be better about it to have my daughter be exposed to the lowest level of chemicals possible
What I would like to know is as follows:
1) what pump would you recommend? (Here is a list of all the ones I would get rebates on http://www.srpnet.com/energy/powerwise/ ... dPumps.pdf)
2) am I good to go with the filter or should I get a new one, if so, which one? (I would like to stay with a DE since I have changed the system to Fiberclear and absolutely love how clean the water looks at that fine filtration)
3) I wanna completely repipe everything, what fittings should I use and why (solid pipe to the pump/filter, or threaded connections etc)? Also should I put new valves in since I am at it or re-use the old ones and replace them later if needed? What pressure rating do the pipes need to have?
edit: the valves for the aerator and slide are letting water through too, what valves are best for that?
I was looking at the Hayward SP3400VSP EcoStar VS, is that overkill? I doubt we will ever do it but the pump should be strong enough for a heater or solar heating system on the roof.
For new valves I was looking at the Jandy 2 to 2-1/2-Inch Positive Seal NeverLube Valve. Are there better ones?
I hope this post is not overwhelmingly confusing but I am obviously new to the whole thing and there are just so many questions
Thank you so much in advance!
