Interesting points about booster pumps, but I'm wondering if the real issue here isn't just pressure, but also water volume. Sometimes clients think they want a "stronger" shower, when what they're really after is more water coverage or volume. I've noticed that swapping to a showerhead designed specifically for lower-pressure systems—like those wider rain-style heads—can actually make the experience feel more luxurious without needing to boost pressure significantly.
Also, boosting pressure in older pipes always makes me a bit nervous...even subtle leaks can cause moisture buildup behind walls or tiles over time. Had one project where we ended up redoing an entire bathroom because of slow, hidden leaks that went unnoticed for years. Have you considered fixtures designed specifically for low-flow or older plumbing setups? They might not give that intense jet-stream feel, but they often deliver a surprisingly comfortable shower experience without stressing the plumbing.
"boosting pressure in older pipes always makes me a bit nervous...even subtle leaks can cause moisture buildup behind walls or tiles over time."
Good point about the leaks—I’ve seen that happen too often myself, unfortunately. Had a client who was dead set on having a powerful shower, so we installed a booster pump as requested. A year later, we were back tearing out tiles because of hidden leaks behind the wall. Not fun for anyone involved.
Also agree on the volume vs. pressure thing. A lot of folks assume higher pressure is the only way to get a better shower, but sometimes it's just about how the water is distributed. Have you had any luck with aerated showerheads? I've found they can make lower-pressure setups feel fuller and more satisfying without pushing the pipes too hard. Might be worth a look if you haven't tried it yet...
I get the concern about leaks, especially in older homes—I live in a historic house myself and have had my fair share of plumbing adventures. But honestly, I think the fear of boosting pressure might be a bit overstated. If your pipes are in decent shape and you've had them checked out, a modest increase in pressure isn't necessarily going to cause problems. I've bumped mine up slightly (nothing crazy) and haven't had any issues yet.
That said, totally agree on aerated showerheads being underrated. I swapped mine out last year, and it really does make a noticeable difference without stressing the plumbing. It feels like you're getting more water than you actually are, which is great for both comfort and water conservation. Still, if someone really wants that stronger flow, I'd say don't rule out a careful pressure boost entirely—just make sure you have a plumber give everything a thorough once-over first.
I hear you on the aerated showerheads—they've been a lifesaver for me too. When we first moved into our old place, the water pressure was so weak it felt like showering under a watering can (and not even a good one...). After debating endlessly with my partner about whether boosting pressure would wreck the pipes, we decided to try an aerated head first. Honestly, it surprised me how much better it felt. Still gentle on the plumbing, but actually satisfying enough that I stopped missing hotel showers.
That said, after a couple years of no issues, we did have a plumber out for something unrelated and asked him to give our pipes a quick inspection. He gave us the green light, so we cautiously upped the pressure just a bit. It's been almost a year now and nothing disastrous yet—knock on wood—but I'm still glad we went with the aerated head first. It was nice knowing we had options before risking any unintended indoor waterfalls...
Aerated heads can help, but honestly, sometimes they just mask the real issue. If your pipes are decent, bumping pressure slightly usually won't cause trouble. Most plumbing can handle more than people think—just don't crank it up all at once...slow and steady is key.
