by Laing Thermotech

Product Description

ACT-909 -TANKLESS The Industries first RETROFIT hot water recirculation pump designed specifically for tankless water heater applications This innovative product design provides a controlled hot water recirculation system for tankless water heaters. The benefits of tankless water heater systems are increased by adding the luxury and convenience of instant hot water at all fixtures in the home thus providing your customer with a true instant hot water system. The ACT-909-TANKLESS installs underneath the fixture farthest from the water heater where hot water takes the longest to arrive. The built-in temperature sensor regulates the system temperature and limits the length of time the tankless heater will be operating during the recirculation period. The system will maintain a constant temperature all fixtures in the home providing the immediate availability of hot water at all fixtures. The built-in 24 hour timer also allows you to select the times of day that you wish to have the system cycle. The timer is programmable in ½ hour increments and multiple on/off settings can be programmed. When the pump is off a built in Auto closure device prevents any future mix of hot to cold or cold to hot.

After a couple of years using an ACT-303 I had to upgrade to an ACT-909 to work with my new tankless water heater. The ACT 909 worked for a couple of days and then stopped. I followed through all of the troubleshooting and determined there is a problem with the check valve that allows water to flow across from the hot side to cold side & then closes when up to temp. I was finally able to talk to a tech at Laing ITT (after many tries to get a real person) to confirm that was the likely problem but I was directed to followup for warranty from the seller. My email to myplumbingstuff via Amazon about a potential replacement went unanswered. I tried the 800 number for myplumbingstuff but was never able to reach a real person. I think the Autocirc pumps are good products I'm just disappointed in the lack of service......

This version of the ACT-909 is for retrofit installations. No return line needed.

I installed an ACT-909 a year or so ago, after we had a tankless water heater installed in the 3rd floor attic. Because it was inconvenient to install at the farthest location of the new part of our house, on the 2nd floor just beyond the shower, I installed it on the first floor beneath the shower. I don't know how our plumbing is run, but the ACT-909 works well in this configuration. The shower used to take a long time to get hot. Now it's hot within 5 - 10 seconds. We are happy.

The unit is completely silent and vibration free. I haven't bothered with the timer, so I am sure we are wasting money there.

I am buying a second ACT-900 for the old part of the house which has the same long lag in receiving hot water on the first floor kitchen.

After a week working fine, there was a horrible knocking noise and several leaks. Repaired the leaks. The knocking persisted, even after performing all the recommendations to remove air in the pipes. The seller sent me to deal with the manufacturer who eventually returned my call. Their tech was on vaca, so they let me speak to the production manager. He totally hooked me up with a replacement.
