Long story short, I bought my new house in May. Noticed the backup valve on the hose was shot as it kept failing into backup mode. This morning I looked in the pool and saw a wheel laying in the deep end (will get it tonight). I assume this thing is >10 years old probably original. Is it cheaper to rebuild or get a new one? Also if I get a new one what do you recommend? I have a booster pump (original) but am not married to it...
