Laing LHB08100081 E1-BCSVNNNW-01 1/2 Pump W/Cord

This pump was a replacement for an older model. Installation was easy. I could use my old pump cover. The pump body screwed in easily. It started up and over time it has become imperceptibly quiet! I make sure that when we go out of town and shut our water supply to the house off the pump is switched off first. When we switch it back on it is so silent running that the only way I can tell it is running is by checking how quickly the hot water comes to our bathroom faucet farthest from the pump.

Bought this pump to replace older model that lasted 17 years. The older model had a timer on it, so I bought the suggested timer to be able to shut the pump off at night (9pm-6am). Installation couldn't be easier - both pump and timer had written instructions. Used the original plumping and screwed the new pump into the older pump's plumbing, which hadn't visibly aged. I carefully removing the original "O" ring from the original plumbing and installing the new "O" ring provided with the new pump. No need to call a plumber! Save $$$!

Quick replacement. I used this pump to replace the old Laing 303 series pump. No soldering was needed. I was able to un-screws the old pump, clean the old manifold, and screw on the new pump with o-ring to the old manifold. The pump I received has a power light and a small turn switch/knob on it. I turned the knob all the way up. I have this pump plugged into a wifi smart outlet which is programmed to come on at specific times (TPLINK HS103) . So far all is well. I got a quote from Benjamin Franklin plumbing for $925. Since I replaced it myself I saved big!

As other reviewers have noted this is a nice do it yourself replacement for the older 303 series, and can be utilized with the existing brass pump housing if you don't want to sweat in the new one (if you do make sure you remove the motors and o ring first). The motor is adjustable variable speed vice constant speed and consumes 12W max compared to 33W for the old unit per the nameplate data. Amazon's specs for this item are out of date. I needed to crank mine up to "4" (a bit past the "ECO" range) to get the hot water recirculating loop warmed up in a reasonable time. I believe it is a little noisier at this setting than the old unit. My old pump lasted over a decade, so we'll see how long this one lasts. Nice product.

My old hot water recirculation pump went out some time ago. I finally got tired of waiting for hot water and searched for a new pump. My old Laing SMT-303-BS is no longer sold, but I found this product (Goulds E1-BCSVNNNW-01) and it was cheaper here on Amazon than anywhere else I could find. This pump is an upgrade from my old one in that it has an adjustable knob, an indicator LED, and an air purge feature. Note that Amazon's product photo is wrong as of the posting of this review - it shows a threaded pipe fitting, but it is a sweat (solder) fitting. The photo almost prevented me from purchasing this product, but the description is right and the model number indicates it's what I needed, so I pulled the trigger. I got lucky, too! I didn't have to sweat out the old pump housing & sweat in the new one. It just so happens that the old brass housing of the Laing pump appears to be identical to the new Goulds pump housing (accounting for some wear and impurities - see photo). Sure enough, the new pump motor and screw ring mounted readily to the old housing (I did swap out the old o-ring). The provided literature is in hieroglyphics, but you can find a better manual with a web search. I've added a few screen captures of manual portions I found informative. The air purge feature worked great and I set the knob between 2 & 3. And just like that, I have instant hot water throughout the house!

Pump only lasted 1 year. Pump is of poor quality and is not recommended.

Used this product to replace a Laing SM-303-BSW pump. The housing is a perfect match so I was able to avoid any changes to the existing copper work. The new pump and retaining ring threaded right on the current housing so the entire repair took less than 5 minutes. The variable speed was an extra bonus as I have been able to maintain hot water at all location while using the lowest setting on the new pump.

After reading some other reviews, I came to the conclusion that this Laing pump would work to replace our older Laing pump that had suddenly just quit working. The best thing about this pump is that it can attach to the brass top of the older pump and eliminates the need to have a plumber come out and replace the whole unit that is either soldered in place or is attached with threaded fittings. To replace the pump, there is a threaded brass ring that holds the pump motor to the brass top that you remove with a large set of tongue and groove pliers (Channel Locks). Remove the brass top from the new pump in this fashion and then remove the old pump from it's brass top the same way. Then, attach the new pump to the old brass top (that is already attached to the plumbing pipes) by threading the brass ring onto the the threads of the brass top. Make sure the rubber o-ring is properly set into the groove in the brass top before you do this. Snug the ring up with the pliers and that's it, you're done. I went ahead and ordered the optional timer for the new pump since our old one had a timer as well. The model number of the old pump is SMT-303-BSW and this new pump was a direct "bolt on" replacement.
