## Questions & Answers

**Q: I have a 4500 sq foot house with 6 bathrooms & 2 jacuzzi's. What size of tankless water heater do I need?**
A: You might want to piggyback two units only one turns on if the 4-5 bathroom usage is adequate, but should you need more, then only will the second one turn on. It's just all going to depend on how many baths or hot water usage is needed. If I had to guess that your family is not taking more than 4 showers simultaneously, then only one 4 bath model would be sufficient. Talk to Takagi, their service was more than helpful. I have the TK-540P-NIH, which handles 3-5 showers at the same time. Its all going to depend on if you have water restrictors inside the shower nozzle. I have run the dishwasher, 3 showers, and laundry all at the same time, and it kept up perfectly. This situation is rare. What is common is 5 of us taking showers back to back. Extremely happy with it. Without rewriting all the above, the accumulative hot water flow is what needs to be measured.

**Q: What country are they made?**
A: The gas flex riser is made in Korea, the water flex risers are made in china but I have no tag on the brass valves as to country of origin. They have performed without any problem.

**Q: Will this work with “ecosmart 11 electric tankless water heater 13kw at 240 volts”?**
A: If the unit has a cold, hot and a 220V line there is a different package for those units without the gas valve.

**Q: will this work with Bosch?**
A: That is a question you are better off taking directly to the manufacturer to get the most accurate answer. I can tell you that I purchased this item and used it in my Rheem tankless water heater installation. I can tell you that all of these fittings are of the highest quality. I was very pleased with them. It is an expensive kit and I didn't need every part included. I could have bought individual pieces cheaper but this kit had everything I needed and I knew it was designed for my intended purpose so it was worth it for me to pay a little more. These particular fittings can cut out several of the plumbing steps included in your installation because the installation instructions tell you what kind of plumbing fixtures to use and how to install them but, looking closer (after I had done all of this extra plumbing work) I saw that these fittings were designed to handle these additional plumbing functions (such as your bypass drain fitting).

## Customer Reviews

### ⭐⭐⭐⭐⭐ Completes the project!
*by L***C on October 12, 2020*

Great kit and really completed my project. The local hardware store as well as the big box hardware stores did not have the gas line I needed in stock or the pressure relief valve for my tankless water heater so without the kit I'd still be without hot water! The flexible gas line made the gas connection quicker and easier. Also the included pressure relief valve saved me from having to go buy it separately. Valves seem to be well made and are leak free so far and fittings feel sturdy and quality made. Time will tell but so far its getting 5 stars from me.

### ⭐⭐⭐⭐⭐ Great kit for making installation easy
*by B***L on November 21, 2018*

I used this to change from a tank water heater to tankless. It was an AO Smith water heater. Everything worked well to hook up the water and gas connections. I really like the shut offs for the ports to flush it out. It allowed the angling of the valves to provided access later for flushing the water heater while still allowing easy access to the shut off values. I am glad I purchased this to complete the installation rather than trying to get pieces one by one or another kit that did not have all the valves and ports this one did.

### ⭐⭐⭐⭐ Four Stars
*by S***Y on July 15, 2018*

Everything I needed to install and feels very durable.
