LF150HA, 3/4" Lead Free Thread for 1/2" Water Hammer Arrestor

Tried 2 different places to get this part, Watts couldn't even help. One place even sent me a "similar item" not even close to what I needed. Supply House found and delivered exactly what I needed in a very timely manner!

Great folks to deal with

Well made reliable product.

At first glance, this looks like a great problem-solver device for attaching a water hammer arrestor onto the back of a clothes washer solenoid valve, where it really works best. The design is simple, and should be easy to install, but it can be quite difficult to secure properly without leaking. Some of the blame can be laid at the feet of the washing machine manufacturer, who thinks that the connections need to be recessed so it can be pushed-up right against a wall. This is not possible in any case because there needs to be some room for hoses and drains behind it. Worse yet, the distance between the hot and cold connections are barely enough to get a finger in between to grab the hose fitting. The recessed ports make it impossible to get a wrench on the connectors in order to tighten them fully, and I had to take the back off of my machine to do it. Even after all that, I still have leaks, so it's back to the drawing board.

You will need to tighten the floating female side into the cast body before installed onto the hose bib. Do this to avoid leaks once installed. Female end of cast part could be longer.

Good price Fast shipping Good shipping updates

Need to tighten the floating side to avoid leaks. Once tightened awesome product. Agree could be longer. A nice update would be a wall hanger for the complete assembly.

There wasn't enough offset from the wall (for the bulbous part of arrestor) - we installed this fitting on the washer and still needed to solder an inch stem to raise the arrestor above the dryer. In hindsight I wouldn't have bought these fittings, instead find one just an inch longer.

I had a small problem with the factory Teflon Tape - had a slight drip on each connection between the washing machine and the factory "T" manifold. The male thread that screws the garden hose swivel connector to the manifold (a factory Teflon Tape connection) started leaking as soon as the water was turned back on. I used a 3/8 inch "Allen Wrench" to remove the connector - noted the factory Teflon Tape was brittle - I replaced it with a high quality Teflon tape and reconnected the manifold & hoses. No Leak =) Also noted the "Watts Water Hammer Arrestor" could not sit vertically side-by-side - had to offset each by 15 degrees.See photos. Easy to Install and Works Great - No More Water Hammer.

Worked at the wash machine water connections on a Maytag. Installed at the other end of the hoses with an LG wash machine. Would have needed an elbow or extension in order for the arrestors to clear the machine.
