Kitchen Faucet Flow Rate, Part II

Not all laundry faucets are wall mount and I think usually have no low flow regulators. Here’s a very good brand (Kingston Brass) that’s inexpensive and good flow rate, 4 gph.

A simple search on high flow rate faucets gets multiple hits on various styles.

I complained to my plumber about the low flow in a faucet last time he was out - and he said, ‘I can fix that’ and a few minutes later the flow was fixed. I should have asked him what he had done...

All of the new faucets I have installed have stupid 1/4” (might even be smaller than 1/4”) supply lines built onto them. They get plugged often. I disconnect them from the angle stop and disassemble the faucet and Blow them out with high air pressure into a container from the faucet side. Then I bleed the supply side into a bucket and observe for any debris.

I haven’t read thru the threads but I recently put a “laundry sink” faucet in. It has no restriction on flow. And no aerator, of course, but has the threaded spigot (redneck!!! 😂).

tuscany is a menard’s store brand only ... store brand plumbing fixtures are a total no-go in my book ...

I found a good number of roughly 4 GPM 4” centers faucets, but... This usage is a kitchen sink faucet with 8” centers.

At this point my only option is replace the brand new faucet with something like what I linked above (and try to figure out something for the side spray) or put a single hole single temperature “drinking water faucet off to the side.

Well, I guess I could really hillbilly it and rig up something from under the sink with a water hose...

I recently replaced the faucet in my office washroom. The new one wouldn’t flow enough to activate my tankless water heater.
I thought I’d just remove the faucet aerator screen, but the entire outlet of the faucet was an assembly with a flow restrictor and aerator all in one. Running the faucet without that assembly splashed water all over the place.
Careful application of a hot soldering iron melted a hole in the flow restrictor. It was kind of nerve wracking because one false move would ruin the whole thing.
I put it all back together and now it works great.

I was able to do much the same with a shower head, many moons ago. :-)

Unfortunately, while the aerator in my new faucet is easy to entirely remove, it doesn’t affect flow rate much. No splashing with it out though (due to the slow flow.)
