I guess the "knobs" are the valves? No heater/no spa? If it's a pool only, not often. The easier access the better though.

My opinion is you have every right to ask for a decent clean up of the job site. Nice IntelliFlo by the way. Initially I thought you were too picky but as the pictures scrolled by, there is enough bad work to hold them to every last detail. Gliu drops are normal and chalk that up to laziness. I lay a towel to catch drip but that's just me. Most glue drops scrape off too. The rest is pretty poor workmanship. You're no going to do much with the paint over spray on the pool sweep booster valve but get everything else fixed. That gauge is a vacuum gauge and should be removed and plugged anyway.

My goodness, that is pretty. Did you get a picture of the basin before plaster? That drain concern is significant. I find it hard to believe that the plaster team plastered over it. These guys are pretty skilled at doing this. I suspect something else may have happened. What size pump is driving the weir? That is a fairly substantial length. Are you looking for a sheer effect into the basin or expecting the water to run down the wall and into the basin? The edge needs to be withing a 32nd of an inch of level for a minimal amount of water to be needed. That looks like it's only within a 1/4" at best and possibly under powered. If the drain issue is real, that may also have an effect as the drains may be partially blocked and an insufficient flow may not be possible until the issue is corrected. It may also present an unsafe submerged suction situation. What did you use to plaster? Different finishes have different start up procedures. Getting your own proper test kit is something I encourage all my customers to do. I have found pool store tests to be less than accurate on many occasion. Hand held electronic testers really don't cut it for homeowners. Adding di-chlor and stabilizer is a great way to overshoot desired stabilizer levels in a pool. I personally prefer to use unscented bleach such as Clorox or other brand that is labeled 5 or 6% for elevating the FC level after the 1st few days and for the next couple weeks during a new plaster start up. If you have an erosion feeder, then tabs are appropriate. The use of added stabilizer is discouraged in this situation as tabs add this as they erode. The type of plaster finish is important here though. While builders can build some beautiful pools, that doesn't mean they can care for them properly. I know of several that are like this. They don't want to know. They would prefer to turn on the system and move on to the next project. Purple Stuff may not be needed if there are no metals in the water. Wasted money if that is the case. Test for iron and copper first. If it is present, find the source. If the test indicates the presence, then it's appropriate. Know the raw chemistry of your fill water. This will help you predict your usage need for certain balancing chems as you go forward. Knowing your pools needs will help you maintain a safe, refreshing, and sanitary body. As I mentioned before, a proper test kit will be crucial for your pool's needs. It will also help you measure a weekly service's ability to maintain your pool should you decide to go that route. Hiring a service does not absolve you of the responsibility. It is still your pool and not all maintenance teams are equal. Scott

Well I have no idea without pictures.
