Not sure if I should keep this as one post or split things up into the different sub forums with so many questions.... We're entering our second season of having a pool and had it re-tiled and re-surfaced it when we purchased the home. The equipment is a mess and I've been limping it along over the last year. I'm ready to start over at the equipment pad and will also be adding solar at the same time. Anyway, looking to get some advice on equipment replacement. Please note I'm stuck with a single 1.5" suction line from the pool. There are two 1.5" returns, one for the pool and one for an old spa. The spa does not have jets (only a single return) and the blower is gone. It's used as a kid pool now.
Currently have a 12+ year old Polaris 280. The booster pump is the same age and has multiple leaks. I've replaced a few small parts on the cleaner over the last year. It looks like the same setup would be $700 - $800 depending on what timer is used. Does it make sense to go robotic instead? I assume it should also help with our power bill not having a booster pump on 2 hours a day. I'd want to keep the cost less than $1K.
Currently a 48 Sq Ft DE. Looking at a Pentair FNS 48 or the Quad DE. The smallest Quad DE is a 60. Any concerns with a larger filter? I only saw a rise of 8 psi (started at 14) over the entire swim season on the current filter last year.
Looking at an Intelliflo VS or VF. Current CA electric rates range from $0.13 to $0.35 and we spend a fair amount of time at the highest level when both AC units are running during the hot months. Is the internal flow meter on the VF worth the added cost or am I better off adding an external flow meter for the equipment pad and one for the solar for dialing everything in and do the math myself for turnover rates, etc.? Is there any benefit to change the equipment pad plumbing to 2"?
Pool has a surface area around 400 Sq Ft. I'm going to add four to six 4' X 12' panels on the south facing roof with full sun. Right now I'm leaning towards Aquasol panels. Should I go with 2" headers or is 1.5" sufficient for 6 panels? The distance to and from the roof is very short. It's a couple of feet away from the pad and up one story. Current plan is to use a Pentair Solar Touch for automation.
Thanks for any advice!
