En breve lo instalo para usarla. Ya la instale funciona muy bien, lo unico no se como ajustar la temperatura del sensor para incrementar la temperatura del agua. Me gustaria comprar un mando a distacia para la bomba, alguien me puede indicar donde?

There are several versions of this pump available under this single listing. I decided against the digital version based one price. The digital pump is basically the same except you can adjust the temperature settings without buying the remote. The water flow version seemed convenient initially, but I didn't like how there was a bridge from the hot to cold water. The kit includes a check valve, but some of the other reviews indicated that the check valve was not very efficient.All that said, I decided on getting the standard version with 12" braided hoses. I installed it according to the instructions with the brass tees on either end of the pump and had a lot of trouble getting the hoses to reach and sit well under my sink. I was also getting a lot of noise transference into the vanity and wall due to the wall mounting. In the third amazon product photo, it showed the brass tees installed on the shut-off valves. This made much more sense to me as the pump would now only have 2 hoses connected to it. This setup is basically the same. You just have a longer connection between the tee and the pump rather than between the tee and the shut-off valves. My installation is in my attached photos. I attached some dense foam furniture pads under the pump to reduce vibration transference and glued some sound absorbing foam to the walls for good measure. The sound was reduced significantly and hot water circulates great. The pump is quite quiet and the main noise is water running through the pipes.The provided braided hoses come have one 1/2" x 3/8" end. Initially it leaked like crazy until I realized that both the 3/8" and the 1/2" nuts needed to be tightened down.For my setup, I connected the power to a smart outlet and just have the outlet turn on and off based on a motion activated switch. Overall, the pump works great, costs much less than other options and my wife now doesn't complain about the lack of hot water.

I only wish that two remote controls would work with this unit. It only allows pairing of one. Very quiet. I've had it for 1.5 years now, running like new.

Es un aparato casi perfecto que ahorra mucha agua y proporciona agua caliente al instante en el fregadero y la ducha. Tras probarlo en modo automático y eco, decidí que funcionaba con demasiada frecuencia cuando no era necesario, desperdiciando gas en el calentador. Ahora lo uso en modo manual con el control remoto. Sólo desearía que hubiera una forma de desactivar el ciclo de una hora que inicia el control.Unas dos veces al año se atasca la válvula antiretorno, a pesar de que tengo un buen filtro en el suministro de agua de la casa y la rejilla de entrada en la bomba. El problema es fácil de diagnosticar y de reparar.Síntomas: Agua caliente en el grifo sólo templada, agua fría en el grifo nunca fría del todo.Diagnóstico: Cierra la válvula de suministro de agua caliente debajo del fregadero, abre el grifo a máxima temperatura. No debería salir agua del grifo. Si sale, significa que la válvula de retención no se cierra y el agua fría retroalimenta el suministro de agua caliente a través de la bomba.Quítala: Cierra las dos válvulas de suministro bajo el fregadero, desconecta el cable de alimentación de la bomba, retira los conectores en T donde se unen a la bomba. Retira la bomba de la pared.Prueba: Sopla por la boca en el conector de salida. Debe estar sellado y no pasar aire. Si pasa aire, la válvula de retención no está bien asentada. Sopla con la boca en la entrada de agua caliente. Debe haber una resistencia inicial, luego pasa el aire cuando el resorte de la válvula de retención permite que se abra.El vástago central de la válvula (cruz interna) sobresale 0,4 mm (0,015 pulgadas) de la carcasa de plástico blanco que la rodea cuando está asentada. La carcasa encaja a presión y no se puede desmontar.Reparación: Utilicé unas pinzas para sacar un poco el pasador central, y luego hice correr agua de otro grifo por el conector de salida para eliminar la suciedad. El agua pasa por la bomba y sale por la entrada de agua caliente. Retira las pinzas y comprueba si el pasador se retrae y asienta correctamente. Repite la prueba de soplado de aire.Montaje de nuevo: Justo al revés. Aprieta los conectores en T con la mano y luego ¼ de vuelta con la llave. No los aprietes demasiado o tendrán fugas.

I have purchased three of these now: one for my kitchen, one for my master bath (my house's plumping is Y-shaped so I need separate ones), and one for parents-in-law as a gift. It is a surprisingly good product for the price (similarly functional models can be hundreds of dollars more). I too was initially skeptical, but I have been using them for 6 months now and they are fantastic. I only run in manual mode so that I activate it whenever I want hot water. Quite quiet and very effective. I had two complaints about the product of which one has now been solved.1) With the remote, once activated in manual mode, the pump stays on for 60 minutes more. The whole point of manual mode is to only be on when I activate it. However, I see that they now produce a version that does not have this 60 minute extended on feature. So one complaint completely resolved!2) Even when the pump is off, water can flow from the hot water line to the cold. As a result, when the cold water tap is on, I get warm water.Note this is NOT because the pump has pumped some water from the hot water line into the cold as some reviewers have assumed. I have a on-demand hot water heater so I can hear it turning on whenever I use the cold tap (it turns on whenever there is flow in the hot water line). The pump has a check valve to prevent water from flowing from cold -> hot, but not from hot ->cold (indeed, you want water to move from hot to cold while the pump is running). It is true that the first couple of seconds are warm because of pumped hot water but regularly warm water is caused by water flowing from the hot water line. Turning the pump off has no effect on whether water can flow through the inactive pump from the hot water side to the cold.However, I have now resolved this on my set up by adding a drinking water-safe solenoid valve to the cold side of the pump. This valve is closed whenever unpowered and open when powered. I got one that also uses 24V DC (the same as the pump) so that I could wire it directly into the pump or use the same power supply. The product proved surprisingly sturdy to getting the cover off to do that (and I didn't want to break it) so instead I just have both the pump and solenoid valve plugged into the same smart outlet. Now, when I turn on the outlet, both the pump and valve activate and everything runs normally and when the outlet is off, my cold and hot water lines are isolated and I have only cold water when the cold water tap is on. If you happen to have lower pressure in your hot water line than your cold, you may also not have very warm water (as most of the water will be coming from the cold line), but this is not my situation. I consider this the ultimate setup (I note a previous reviewer added a manual valve to do something similar, but I didn't want to have to bend down under the sink and turn the valve every time I wanted to turn the pump on).The cheapest drinking water-safe valve I found was about $120, so I recognize that if PROZRTED wanted to add this feature built-in that 1) it would cost a lot more and 2) it would be a bulkier product, but I would have been happy to pay the extra for the perfect product. Hence, I call it a "near-perfect" product. Is it really a big deal to have warm water in my cold tap or to have my water heater click on when I only want cold water? No, of course not, but it is less than ideal. All-around a great product and worth getting, but it can be made to be even better.Details in case anyone else wants to copy my setup. I got a 1/2" pipe (to match my pump) drinking water-safe solenoid valve. It's female 1/2" NPT on both sides. Whatever this pump's product page says, the pump and the T-joint fittings are not NPT but NPS. NPT and NPS have very similar threads and will engage together but NPT seals by the threads tightening into each other because of the taper and NPS seals by screwing all the way in and pressing against a gasket, so, in general they don't seal together. NPS male will seal with an NPT female if you just add a ton (like 6 turns) of teflon tape to the male, that's what I did for the pump to solenoid valve connection, but NPT male will NOT seal with NPS female. For the valve (1/2" female NPT) to the T-joint (1/2" female NPS), it was quite the challenge as it is really hard to find NPS couplings in the US (and I really wanted to ensure any I got were rated for drinking water so I didn't want some random ones from the internet). I eventually found 1/2" male NPS to 1/2" male NPS at a sink supply store (marketed at a male thread shank assembly, the guy at the sink supply store was kind enough to cut the really long side of this item down for me to make it a little neater looking). I actually manage to fit one of the gaskets that came with the pump into the downstream (i.e. cold line) side of the valve and put a ton of teflon tape on my NPS male shank (not totally sure if it's sealing against the gasket or teflon tape, but all I care about is that it doesn't leak). The side with the T-joint worked perfectly since that is 1/2"NPS male to 1/2"NPS female. The solenoid valve doesn't come with a 120V AC-24VDC power supply, so you need to either buy one or use one you might have lying around. I attached a picture (the black tube in the picture is the dishwasher drain line).

Just installed it, so far doing the job. The hose installation is poorly designed. It should have elbows for hose connections instead of horizontal. Hoses supplied were too short without the elbows.The pump is very quiet. The down side is you get warm water from the cold tap but that is the way it works.

La bomba es muy silenciosa y cumple con su cometido. La razón de no ponerle cinco estrellas es que las instrucciones no son detalladas por lo que debes intuir donde se conecta la linea de agua caliente y la linea de agua fría, siguiendo el flujo que marca una pequeña flecha (triángulo en realidad) en el boton central de la bomba (el flujo es: de caliente a fría). Por otro lado, las mangeras que vienen son muy cortas, el soporte para la pared es incómodo y no te permite más que una sola posición. Si sabes lo básico se plomería deberías poder instalarla con algo de esfuerzo. Finalmente, recomiendo comprar el control remoto si deseas usarla solo en modo manual, cómo es mi caso (aunque también lo requieres si deseas ajustar la temperatura del agua a un valor más alto o más bajo que el estándar).
