There was a strange noise coming from upstairs: a hum that sounded like the shower pump, except that it kept going on and off.
Mrs M and I looked at each other, quizzically. I paused the film we were watching on telly and headed up the stairs. Just as I got to the top, Son walked out of the bathroom with a towel wrapped around his waist. “Shower’s broken”, he said nonchalently, as he went into his bedroom and closed the door behind him
I went into the bathroom and pressed the shower button. It whirred into life with a loud hum but was silenced after just a few seconds as the pump shut down due to no water coming out.
I checked the pump – located in the airing cupboard. It looked OK: no signs of leaks or anything, so I rebooted it (I turned the power off and back on again). It was still the same. I did a diagnostic check on it, using the app on my phone, but it said that the shower was in full working order.
Then I turned on the taps. Water flowed from the cold, but nothing came out of the hot. This had me puzzled and I spent ages checking around the hot water cylinder, but again, everything looked OK.
Flummoxed, I turned the taps on again and watched as the cold water flowed out, but then started to slow and quickly stop.
“Aha!”
I got the stepladder out, climbed into the loft and looked in the water tank.
It was empty, save for a puddle of lime scaled water at the bottom. The red ball float hung forlornly in the air, when it should have been floating atop two cubic metres of water. I wiggled it it up and down, but nothing happened. I checked the header tank and that was fine, so the ball valve in the main water tank was obviously knackered.
This isn’t the first time this has happened. I’ve probably replaced that float valve three times in the past five years.
“Can you fix it?”, Mrs M shouted up, a slight note of panic in her voice. “I’ve got that big meeting in the office tomorrow, so I’ll need to shower and wash my hair.”
“I’ll see what I can do”, I said reassuringly.
I looked at the ball valve carefully. The plunger felt stiff and pretty much immovable. I was unable to get at the innards as the cap was sealed tight with limescale and wouldn’t budge, even using my biggest pipe wrench.
It was 9pm on a Sunday night, what was I going to do? And why do these things always go wrong at the most awkward times?
And then I had a moment of inspiration (or was it desperation?)
I hit it. I got my biggest spanner and I hit the valve. Hard.
Water started to dribble from the outlet. I hit it again and the water flowed out quicker and before long, the tank was full again.
I went to the Plumbing Merchants this morning and bought a new valve.
I should have bought a spare.
