Yeah, I’ve seen this play out a few times in older buildings. Here’s what I’ve learned the hard way:
- Boosters are tempting when tenants start complaining about weak showers, but they’re not a magic fix. If your pipes are original (especially old copper or galvanized), you’re basically stress-testing every joint and pinhole.
- Had a tenant once who insisted on “better pressure.” Put in a booster, and within two weeks, we had a slow leak behind the kitchen wall. Water found its way into the subfloor before anyone noticed. Ended up costing more than just living with low flow.
- Inline filters are another double-edged sword. They help with sediment but always drop pressure a bit—sometimes more than you’d expect if they clog up fast.
- If you do go for a booster, at least check every visible pipe and fitting first. Look for green corrosion or any damp spots. Even then, leaks can show up in places you can’t see.
- Sometimes it’s worth getting a plumber to pressure test the system before making changes. Not cheap, but cheaper than water damage.
Honestly, unless there’s a real need (like appliances not working), I usually tell folks to stick with what they’ve got if the plumbing is original and hasn’t been touched in decades. Chasing leaks is no fun—especially when they pop up at 2am.
One thing that helped me once: swapped out some of the worst sections of pipe before adding anything new. Not always practical, but it gave me peace of mind.
Just my two cents... sometimes “good enough” really is good enough when it comes to old plumbing.

That line about “chasing leaks is no fun—especially when they pop up at 2am” hits home. Had a call once where a booster pump went in on a 1950s system, and within days, water was seeping out from under the baseboards. Turned out the old solder joints just couldn’t handle the extra pressure. The owner was convinced it’d be a quick fix for the showers, but ended up with a torn-up kitchen floor and a week of drying out subfloor. Sometimes those “quick” upgrades are anything but.
I do think pressure testing is underrated, though. It’s not cheap, but it’s saved me from a few disasters. I’ve also seen folks skip checking the pressure regulator entirely—sometimes it’s just stuck or set too low, and you don’t need a booster at all.
One thing I’d add: if you’re set on boosting, at least install leak detectors in the worst spots. Cheap insurance for peace of mind. But yeah, sometimes “good enough” really is the best you’ll get with old pipes.
- Been there with the “quick fix” turning into a week-long project. Once had a tenant call about low pressure, and after installing a booster, the old copper pipes started weeping like they’d watched a sad movie.
- Pressure testing’s saved my bacon more than once—worth every penny, especially in these vintage buildings.
- Leak detectors are a must. I stick one behind every dishwasher and under the kitchen sink. Cheap peace of mind, and it’s way better than explaining water stains to a new renter.
- Sometimes you just gotta accept “good enough” and keep the number for your plumber handy... just in case.
Pressure testing really is the unsung hero in these situations. Folks underestimate just how much old copper can hide until you crank up the pressure—then suddenly you’re chasing leaks all over the place. I’ve seen more than one “simple” booster install turn into a full repipe job. Leak detectors are great, but honestly, nothing beats catching issues before you close up the walls. Sometimes “good enough” is all you can do, but I’d rather spend an extra hour testing than get that 2am call about a ceiling drip.
Yeah, I learned that lesson the hard way. Thought I could just swap in a booster and call it a day, but nope—ended up with a slow drip behind the drywall. Wish I’d spent more time pressure testing before patching things up. You’re right, it’s worth the hassle.
