Question: Step 2 of installation instructions says "Drain remaining water from hot water spigot" after emptying the taps. Does that mean drain the whole tank?
Document: Same product as sold at local home improvement chains but at a lower price... could be refab but made no differance works well lasts long. All the ingredients are there with instructions (works great with the 3/4 inch &#34;Shark Bite&#34; hot water tank hose connector sold at Depot/Lowes).
If you have a water conditioning system in your home, you need to ensure that the Watts pump is not operating at the same time your water conditioner is preforming it's "conditioning cycle!" That is the beauty of the Watts system with the built-in timer!The installation of the Watts pump was extremely easy. In fact, it took longer for the hot water heater to drain than it did to install the system.
It took longer to drain the hot water lines than it did to install the pump and less than 10 minutes to install the valve. It is around 70 feet of pex piping to the sink above the garage where i installed the thermal valve and the shower there has instant hot water this morning instead of taking 2-3 minutes as normal.the pump makes no noise and can be switch off with the switch on the pump.
Works as advertised and upset I didn't know about it sooner. Incredibly easy to install. Turned off the water/gas to the tank, unscrewed the hot water outlet, installed the pump and reattached the outlet to the pump...done in less than 5 min. The undersink unit went on even easier. If you can attach a garden hose, you can do this. No need to hire a plumber IMHO. Had hot water in less than 30 secs where it used to take 2-3 minutes.
My wife said, "After 19 years in this house I finally have instant hot water in my bathroom"? I installed the pump and valve as indicated in the manufacturer's instructions. On a scale of one to ten as to difficulty of installation for a DIY Selfer I would give it a 3 out of 10. I placed the pump at the hot water outlet of the water heater.
The addition of the Hot Water Recirculation Pump has save gallons of water from the time it was installed. Hot water flows now in seconds as to opposed to 2-3 minutes previously. It is fairly easy to install with a limited amount of mechanical aptitude as the instructions are very thorough. There is a little hot water bleed into the cold side but that is negligible and part of the design.
Bought this unit; Paid $300.00 for installation; Paid $200.00 for removal.System does not work. POOR INSTRUCTIONS. NO TROUBLE SHOOTING HELP.DO NOT BUY.To add to all this water Pressure in the FAUCETS dropped - need to get this repaired.My experiment may cost me well over $1,000 in drain.
I had it for a month now and it works just as I expected, hot water in 2 seconds, cold water takes a little while (less than 1 minute) to go really cold., which is no big deal to me. Installation took me about 30 minutes as a not-very-handy person
I installed the system two days ago and so far the results are great. I went from getting hot water in 1 minute to having hot water in 2 seconds at my kitchen sink. I need to install the additional sensor valves to get hot water at other locations.Installation took about 20 minutes, porbably could have been faster if I was trying. I only needed 1 wrench to do the entire install, though a second smaller wrench would have been easier.
After installing it , it did not work. My plumber rechecked all his installation work. It was correct. The so called installation instructions do not include a troubleshooting page and neither does the website. We ran the water pipes and there was no air in the lines . So the plumber took it off and did a check test with water in a shallow pan. When he plugged it in, the impeller didn,t move and no water was being pumped.
Answer: yes
