So here is cliff notes:
-Bought new house with dirty pool and pump is currently not working.
-Two pool companies came out to take a look and both recommended we drain pool to clean it and get a new pump. One of the companies said they might be able to get current pump working but were not sure.
-If I try to turn pump on it makes some noise and breaker trips.
-The only clean out is on side of house, which is not ideal for draining pool.
-There are solar heating things on the roof, but previous owner says it doesn't work... did not say why. Oh and 2 story house.
-Pool is 16000gallons or so.
-Current pump is 2hp.
-Live in CA and we already use too much electricity and any additional usage, eg pump, is going to be at PG&E's tier 4 rage, $0.30/kwh or so.
-There seems to be two pumps actually, the main pump is 2HP and uses 2" pipe to pool. There is a second pump with like 1.5" pipe and it is 0.75hp.. I dunno what this is really for, lol.
So not really sure what I'm doing, but nothing is that hard to learn. Looking for some advise on where to start, I've tried to read up a bit but end up with conflicting information.
Both pool companies recommend we drain pool to clean it. The only clean out is on side of house which is not recommended. Even more everyone online acts like you should never need to drain a pool unless doing repairs. I've found some before/after pictures and seems like with right chemicals and working pump/filter you can clean anything. But why did both companies that looked at pool say to drain it? Seems like pain in the butt to drain it for number of reasons if it can be avoided-- well mainly I only have the clear out on side of the house and I have a sump pump but I'd have to get more tubing to reach. Wouldn't be end of world, probably put it on low speed and keep and eye on stuff in house, but still I'd like to avoid this is possible.
If I skip the draining plan my first step will be to get pump working. I'd like to just go buy a variable speed pump to try to save electricity at all costs... should I worry about the solar heating setup? Some seem to say if you need to pump to 2nd story the variable speed pumps are worthless because you cannot use any of the lower settings... but even if true, I wouldn't want to use the solar heating stuff all the time, right? At first I'd be fine bypassing it, and worst case later on if I get it working only certain times of the year I'll even want to use it, and if I'm then unable to use lowest speeds on pumps so be it? Is that reasonable? I'd rather get a bubble cover to try to keep heat in than spend extra money using solar heating on roof when possible.
Basically how bad an idea would it be to buy an IntelliFlo VF? http://www.amazon.com/Pentair-011012.../dp/B000N56HP4
Order that today, try to get it installed this weekend, current filter seems good, and then look into chemicals needed to fix pool?
Also FWIW here is pool:
