Shower cartridge leaking. Part # 158084 2-5. Eight years old, clean, looks like new. Do I need a new cartridge or is there something else I can do?

SOURCE: replaced a moen cartidge and now the water is not hot in shower

make sure when you turn on the hot and cold shut off valves all the way and turn the moen on after that. Some times I would get that problem if I turned one(either hot or cold) off then tried the shower.

hi... yes that's a very common issue with moen "cartridges" -- it's very simple to fix..... grasp the handle and give it a gentle tug upwards when the water is on... if it retracts again, pull the handle out again and tug again but this time a bit harder. Not sure what causes this on new cartridges but it will fix your issue.

It is stuck, they come out very hard and a puller is made to make removal easier.

There are two O rings in the spout body that need to be replace with new and lube the
new O rings with vaseline. If your water is too hot, this will dry out the O rings. Normally
your hot water shouldn't be more than 120 degrees F. You can check this by holding a
thermometer in the stream of water with the hot on only.

Grohe has a lifetime warranty on them. I have taken many Grohe's back to the wholesaler
and they just give me a new one, no questions asked.
