recirculation pump

Hello all, I am new here so I don't know if this is the best forum thread to post this, so just point me in the right direction if that happens to be the case. My situation is this though. I just installed a new tankless water heater in my home after the old tank style finally bit the dust. In...

So I got my external tankless installed and the water heater out of the attic. So far, so good—very pleased with its performance. However, when I bought the unit (RU199en w/ "Circ-Logic"), I also bought a recirculation pump—the GTK03. I couldn't get that to work; I installed it with a crossover...

The hot water recirculation line is a dedicated line and used a Laing SMT 303BSW pump and is plumbed to the bottom of the hot water tank. I found out that the recirculation was not working because the pump was dead. I replaced it with a Laing LHB08100081 Low Flow Circulating Pump. It is...

I have a question related to the radiant floor system I am installing. Context: The previous owner of our homes (two located on one property 60 feet from one another other) had ½ PEX oxygenated lines run throughout the entirety each structure. Both homes are Insulated concrete form...

We just moved to a new home after 20 years in a home with a dedicated hot water return / recirculating pump system. This new home (built 2014) has no recirc system despite being 4300 sf in size, and I guess we were spoiled before, because waiting several minutes for hot water to show up in the...

Hello. I'm a new homeowner and am planning to install a timed or flow sensor-triggered recirculating pump at my water heater as well as sensor bypass valves under my kitchen and bathroom sinks. But I have lots of questions/concerns about how this will affect my water softener. I’ve attached a...

Renovating 50 yo house. Second floor is gutted, most pipes are now accessible in the floor. My water heater closet is about 2ft square. Clearly too small for a pex manabloc. So can I mount a pex manabloc in the garage 30ft away from the water heater while useing a recirculating pump to prevent...

First time posting here. I've spent quite a while searching through the forums for an answer, but haven't found exactly what I need. I am considering installing a recirculation pump to reduce the time and waste it currently requires to get hot water to the fixtures farthest from water heater...

Hello All - I'm looking to install a timer based recirculation pump for my hot water lines. My design is below. A couple of things to note: The master bath and basement sink are the furthest fixtures from the WH The hot supply to the basement sink will be disconnected and used as the return...

I am planning on replacing the polybutylene pipe in my house with PEX-A basically using Uponor's "Structured Plumbing" recommendations. I'd like to add an on-demand recirculation system while re-piping. I have a ranch house with everything on one level, the pipes run in the crawlspace under...

I have a renovation of two 8x10 bathrooms on top of each other (8ft ceilings), serviced by one tank right next to lower bathroom. It's all conditioned space. I'm not 100% sure what the plumber plans, but I can't imagine a line longer than 32ft from the tank (probably the upstairs rain shower...

When the recirculating pump begins to run all of the showers drip profusely. The house is new and the builder replace all the valves for the showers but it still occurs wasting thousands of gallons of water.

I was able to integrate an RF remote to control the internal recirculation pump in the Navien NPE-a series tankless water heaters. I own the npe-180a. The video is for informational purposes only and I don't make any warranty assurances.
