Good deal on protection

I'd been looking for a good water damage prevention device for a while, and the Autostopcock ASV2 caught my eye during a seasonal sale. The price was really competitive compared to other systems I looked at, especially for what it offers. I snagged a pretty decent discount, which made the decision easy. Setup was okay, took a little time but nothing too crazy. For the money, I feel like I got a solid deal and some good peace of mind. Definitely a worthwhile investment for my budget.

Reliable system as always

This is my third purchase from Autostopcock, this time for a new rental property. I got another ASV2 unit and a few extra wired leak sensors. Just like my previous orders for my own home and another rental, the delivery was prompt, reaching me in California within a week. The installation was straightforward since I'm familiar with their system now. It's reassuring to know I have their reliable flood prevention in place. Never had a false alarm, and it gives me confidence that my properties are protected, even when I'm not around.

ASV2 works well

Bought the Autostopcock ASV2. Installed it myself. It detected a small drip last week. Shut off water quickly. System performed as expected. Happy with purchase.

Good valve, easy setup

I grabbed an Autostopcock ASV2 a few weeks back after a small scare with a leaky pipe. It arrived pretty quick, like 4 days to my place in Ohio. Hooking it up was less of a headache than I thought it'd be, even for someone like me who's not super handy. The instructions were clear enough. It's just sitting there now, doing its thing, and I feel a lot better knowing it's watching out for stuff. My water bill actually went down a bit too, which is kinda neat.

My house was built in the 70s, will this actually fit with older plumbing? Or is it more for newer builds?

P Paula G. 1 month ago
It should fit fine. It's just an inline valve, so as long as you have standard pipe sizes, a plumber can install it.

R Rosa 1 month ago
Yep, it's compatible with pretty much any standard mains water pipe. My house is even older than yours and it was installed without any issues. The main thing is having space for the unit and the plumber knowing what they're doing.

Just checking if anyone has experience with their return policy? What's it like if it doesn't work out?

R Renee V. 1 month ago
Returns were straightforward for me. Had an issue with a sensor, sent it back, no fuss.

I haven't returned a full unit, but I exchanged a faulty sensor once. It was okay, just make sure you keep all the original packaging and contact them within their specified return window. Read the fine print on their site.

Thinking of getting an Autostopcock but worried about installation. Do I really need a plumber for this, or can a DIYer handle it?

B Ben H. 1 month ago
Nah, you totally need a plumber. It's hooking into your mains water, definitely not a job for someone without experience unless you want a bigger leak problem than you started with.

It depends on your comfort level with plumbing stuff. The company says you can DIY if you're handy, but I'd still recommend a pro just to be safe. It's peace of mind, you know?

How does Autostopcock compare to something like Flo by Moen? Is one better than the other, or are they pretty similar in terms of protection?

K Kevin 1 month ago
Flo is good, but I went with Autostopcock because it felt more robust, especially for freezing temps. Plus, it's a UK company, so support might be easier.

They both do the job of detecting leaks and shutting off water. Autostopcock tends to focus a lot on the freezing pipe aspect too, which might be a plus depending on where you live. Flo has good smart home integration though, so it really depends on what features matter most to you.

Anyone know if these things actually work if the power goes out? Or am I screwed if there's a blackout during a leak?

S Sam Silva 3 weeks ago
Pretty sure they're designed to handle power cuts. I remember reading that somewhere, like it has a backup or something. So you should be good.

A Anna S. 3 weeks ago
Yeah, they do work. The main unit has a battery backup for the control system, so it'll still detect leaks and shut off the water even if your power is out. Saved my buddy's basement during a storm.
