My kitchen was remodeled and I noticed since then the water pressure for new area has been low (hot and cold). Previously we had one sink and dishwasher, now we have
- Two Sinks
- Dishwasher
- Instahot
- Fridge
- Spigot running to outside
The line serving the original sink was 1" — drawn down to 1/2" in the crawlspace and then up to the sink. They extended the 1/2" in the crawl space in the following way
– pipe1: first sink (hot and cold)
– which then T's to
– pipe2: fridge (cold only)
– pipe3 (hot) : goes to sink #2 hot and dishwasher
– pipe3 (cold) : goes to sink# cold and instahot
– pipe4 (continues from pipe3 cold) : runs to spiggot
Could the water pressure issue be related to using the 1/2" pipe to connect to every outlet? Should 1" been run to each location and then each reduced to 1/2" closer to outlet?

Your problem is caused by the plumber down sizing your piping to 1/2". This acts as a restriction to water flow. Replacing the 1/2" piping with 3/4" or 1" pipe will resolve your pressure and flow problems.
