Easy to install and very reliable

Love how quiet this thing is compared to my old one. Especially nice how it connected right up to the plumbing from the existing pump. Would definitely purchase again.

This is the second one I have purchased. I have used the other one for three years in an outside location and it has worked flawlessly.

To replace the old 3/8 pump in the RV. It fits perfectly, very low noise, most of all, no leak.

Only 2 months in, so durability not evaluated yet.Overall whilst I haven't experienced any measure of longevity yet, the fit, form and function of this fresh pump seems to be quite the value for basic needs such as mine. Surely not the same total experience as a higher flow pump with multiple diaphragms and increased noise abatement, but for those who don't need such a premium experience (with quite dear costs) this pump is quite nice and presents much better value IMO.Bottom line:- Noise level: Not measured, but quite acceptable to me. With it mounted directly under the berth I do hear it throughout the boat, however at absolutely minimal volumes that I don't foresee waking anyone except the lightest sleeper. If the tank goes empty and it starts pushing air it will hammer a bit. Some day I'll break out the db meter and measure this.- On demand sensing works great - when I turn on the faucet, water is there and continues to be there. This is perhaps the most important aspect to creating an at home experience - no footswitches or pumps, not buttons, just a regular ole faucet.- No hammering or surging even with just a single diaphragm until water gets low - if it starts drawing air then it hammers. To be frank I like this as I don't have a gauge in my fresh tank, so this acts as my alert that water if very low.- While I have only two faucets, the flow is quite sufficient. Wash dishes, even rinse down cabin floor or countertop without any problem.- Same install as any other pump, quite easy particularly when combined with pex.I have to remind myself to take some photos / videos for everyone. I used this to replace a manual freshwater plumbing system in my sailboat and honestly I kind of hate the maritime industry, so when I saw an item that was more appropriately priced for it's design and manufacturing costs, I decided to give it a try.I'm very glad I did, this little guy so far is proving itself out very nicely. I've already recommended it to several rag haulers who are still pumping faucets.

Pump went into a fifth wheel. Quieter than the pump I replaced.
