Long time for hot water to reach bathrooms
frankporath

We have a very nice 1960s ranch ... but... it takes a full 30 seconds for the hot water to reach the bathrooms. This is a single floor layout, so a recirculating plumbing stack for a multi-story building wouldn't work. The plumbing is exposed in the basement, so it is accessible. Aside from installing instant water heaters at the fixtures, what can we do? Please advise, as this is the only big frustration we have for this otherwise charming home we've spent a good deal of effort on.

You can install a recirculating pump. A little plumbing and electrical work and installing the pump at the farthest outlet. The pump will recirculate through the cold waterline. Recirculating is started with a push button or motion sensor. Taco makes a system and others too.

Is this a new problem or an old one?
How far are the bathrooms from the water heater?
What is the water heater thermostat setting? water temp?

A pump can help, I just don't care for one, it does move hot water around even when you sleep - a waste.
What I do, and I live in a drought area, is I catch the cold water in a 5 gal bucket till it turns warm, then use the water in the bucket for irrigation. This way I don't need a pump and I keep the Department of Water off my back (no fine for excessive water use).

The system I'm talking about only pumps hot water when needed, not a constant circulation. It uses a thermostat and a switch when needed.

I have a Chilipepper pump that operates with a push button. You push the button and do something else for 30 seconds while it recirculates, then you have fresh hot water at the tap. It shuts off as soon as hot-temperature water reaches the pump, which mounts underneath the sink in question. Google them they are probably still in business.

If you have two sinks in the bathroom do you have to install a recirc pump on both?

No, the one pump will take care of both

I have multiple pex manifolds, will that dictate how a recirculating pump is installed?

I don't think so. The pump is usuall installed under the sink.

I agree with ed21 on both answers.

I want to install a Taco 006-ct-usk pump under my sink. The first step is to remove both shut off valves and install the provided Tee's, however the valves are connected to pex tubing and appear to be permanently fastened. Does anyone know how I should proceed?
