How often do water pipes under bath need to be thoroughly serviced? First, hot tap bath had no water; this was fixed and then days later fitment blew off the cold water pipe, again under the bath. What could be the connection between these two incidents?

Is there a chance the pipe froze? Frozen pipes would explain no hot water, and also would explain the pipe joint blowing apart.

What kind of pipes do you have and what fittings, are they Sharkbites, solder, threaded, or what

Pipe did not freeze. Bathroom is upstairs and gets heat from downstairs and above.

I have copper pipes and fittings. Could you please tell me why does it matter what type of pipes and fittings (Sharkbites, solder, threaded and Copper)? Thank you so much.

You said a fitment blew off so we need to know what pipe you have and what fittings are used. I now see you say you have copper pipes with copper fitting so we will assume all fittings are soldered, OK? Copper sweat fitting do not blow off unless they were improperly soldered. Who did the work?

Hot tap in bath didn't work, so called a plumber to fix hot water pipe under the bath. After he left, fitment in the cold water pipe (also under the bath) blew off. Why? Thanks for helping.

I meant to explain that hot tap in bath did not have water for months (could only have showers, not baths), so a plumber was called to fix it.

Call the plumber back and tell him a fitting lew after he worked on your tub, he may have disturbed something. Then again, a copper fitting properly sweated does not blow off.

That gets me thinking. Many thanks for your time. Have a good week.

You are welcome. I am a bit curious but do thank you for your repeated good rating if my answers. Usually this site only allow you to rate someon once, after that you must rate 5 other folks before you can come back to me. How are you able to do this repeated rating?/ Again, glad they were all good repeats.

It is the first time I use a site like this. After reading your 3 answers I noticed that I was supposed to rate these. So I rated each one without knowing that you would know my ratings. You have 40 years of experience and spent time explaining to me

Why is pipe work under the bath is more prone to need repair than any other pipe work in the property?

Also, how to take precautions so that pipe work does not cause problems such as flooding when property is empty?

For background

I don't really think they fail more than other pipes. If you are going to leave the property empty for extended periods you should always close the main supply line into the home, open a tap to releave pressure. If freezing temps are at all possible there are many more steps to take. Will the home stay heated or will it freeze?

Turn off water at the meter, shut off hot water heater and drain the system through the lowest fixture.
