Tap water is generally alkaline to minimize water pipe corrosion, if it's reading 5.5 I would recommend you calibrate and/or check your meter. I use Aquarium drops for accuracygot myself a pH meter for the current soil grow. should you go soil-less/hydroponics, then pH meter is essential tool.
i noticed that our tap water was close to 8.0 pH last winter, and today its 5.5 pH. temperature would also be a factor in that difference in pH measurement. i was using pH Down solution in winter/spring, now using pH Up solution to adjust the water/feed.
it's good to eliminate pH as an issue.
I did not use a PH meter for the first 5 or 6 grows. My tap water after going thru an inline filter is about 7.5 but I did not find that out until after about 5 or 6 runs. I would assume my yield/quality were lowered but the bottom line is we are growing weed. Weed is a weed so while it will thrive in ideal conditions it will also grow in less that ideal conditions.
Can this be had for under 3 figures (or there abouts), I'm very small scale & don't have funds to go lab grade.Get a ph meter. A decent one. Make using it like muscle memory every time you water. If you find that it’s stable then after a bit just use it to verify if you want. It’s so easy I just always check and adjust when needed.

The only thing that bugs me about mine is that it does not default to zero out of water, like the TDS meter, in water seems fine though.
Yeah, I keep it wet but has never defaulted to zero, the reads have been good testing with distilled so I haven't sweat it as the reads seem to match up.It's not supposed to. The meter has a bulb that is always wet. If it drys out it will damage the sensor. Always keep them wet (usually a sponge in the cap) or even water in the cap. I just dip the cap into the nute solution when I use it to make sure the sponge is always moist.
