Questions & Answers

The valve I'm using right now is a 100xl- 4 m7. Is this the same valve as the one in the previous picture?

Yes, that is correct.

I'm having trouble finding the 3/4 LF100XL- Is this a typo and it should be 3/4 LF100XL-150 on Watt's site? 4 M7 (ordering code 0556000 from Watts)?

LF100XL- is a term that should be looked up. 150 br>The main difference between this and part number 0550600 is that the former has a 4" probe while the latter has a 3".

Is this compatible with a Bradford White 40 gallon tank?

Your best bet is to take the number off the tag and look it up on the Watts website; there are a lot of different types and brands of water heaters, as well as multiple models within each brand. With the original part number, you'll have a better chance of getting the exact one you want.

There is a lack of current product model references, as well as a poor description
3/5

Given that my first attempt included references to manufacturer's product models and descriptions in the hopes of assisting others, this was my second attempt. That, however, is against Amazon's terms of service. ugh. br>br>If you're going to sell from a batch that's so old that the manufacturer no longer uses model references, you should at the very least have a complete description of what you're selling. Because the length of the "T" isn't specified in the product description, I had to rely on some Q&A responses. A to see if it was a 3" or a 4" hole. "3" appeared to be the general consensus. My package didn't contain anything like that - 4"br>br>I'll refrain from referring to current models of what this corresponds to - not having to repeat all of that effort - sorry. The product is good, but the listing isn't. Who knows, you might get 3", 4", or even more. Future shoppers, best of luck!.

Installation is simple
5/5

My motorhome's hot water heater area was gushing with hot water. When I opened the access door, I discovered the pressure release valve was leaking profusely. On that trip, I simply turned off the hot water heater, and when I got home, I ordered the 3/4 LF100XL. I used a crescent wrench to remove the old one, put plumbers putty on the threads, and then installed the new one by snugging it up slightly with the crescent wrench. The issue has been resolved; there is now hot water and no leaks! This is an excellent valve.

It perplexes me because I assumed it was self-explanatory
3/5

I ordered the long reach valves, but what I got were the 3 3//4 inch valves. I returned for a refund because the part numbers did not match those on your website. I'll have to put on some gloves and go to a local hardware store (which is why I ordered from you). I'm attempting to stay away from the covis!.

It was an excellent solution
5/5

The price was reasonable, and it arrived on time. It was a simple installation, and it perfectly replaced the old valve. Remember to turn off the water inlet valve and drain the tank below the inlet where the old valve was removed; otherwise, you might end up with a big water mess!.

This is a simple fix
5/5

My water heater has found a new home. The replacement and repair of the leaking took about 30 minutes. That's not bad for a ten-year maintenance period!.

The issue has been resolved
5/5

Following the replacement of our boiler, a professional informed me that I required a new hot water heater. This fixed our problem for a lot less money than a new heater would have cost. Thank you very much.
