My shower and pump is about 4 years old, recently the shower does not stop instantly when i turn it off. Anybody got any ideas.

Turn it off 30 seconds before the end of your shower.   LOL

Is it just the residual water draining out or does it keep on dripping?  Does the pump stop?  I'm not getting what is the problem?

Yep stops but about 40 seconds after i turn off.

My Mum's shower in U.K is like that.. 

As above, turn it off 40 secs before you normally would ????????

Then I change my previous post to 40 seconds!    LOL

Are you talking about the pump or the valve in the heater?

An overhead ceiling rain shower head typically can do that as the whole head is full of water and needs to empty.

In reverse, when you start the shower does it takean equal amount of time to fill the head to a full on spray?

If it's just 1 valve to control water on/off, and that worked normally, until recently, then that's where I would focus my troubleshooting. 

It sounds like your pump and pressure switch is set up in a control loop so that your pump continues to run until the system pressure is restored and then switches off. If that is the case remove the pressure switch and check whether its damaged. Also check the pump suction and make sure that there isn't a partial blockage, which would mean recharging the house reticulation is a little slower. These are the two controlling factors in your system unless you've got an inline filter for debris as well. If you have an inline filter then clean it out.

Are you saying it keeps running at normal levels after the valve is closed or just keeps dripping for awhile afterwards?  As mentioned above my rain shower head will keep dripping for a minute or so, never really timed it, after turning it off.  I think it is likely a siphon effect of the water left in the pipe.

Why not turn the shower off as soon as you start to shower ? 40 secs should be enough ????

If the running water is kind of hot means the pressure switch of the water heater not functioning well. 

Water runs out by overheating.

I am talking water flow !

Use the the tap/faucet and not the push button on the heater?

No, it flows instantly.

Good idea, i am thinking that there might be a filter blockage.

keeps running normally.

Aussies like long showers, thank you. They tell me that it is the Poms who tend to be rather quick. ????????   just an old joke, no offense please.

Interestingly some high power electric showers  are designed to run for several seconds after turning off to avoid damaging the heating unit.. Clever.

Probably a weak coil in the shower heater solenoid valve (walve?) or just gotten sticky for some reason.

Had this with Panasonic heaters. If I pressed the on of switch a couple of times, it would stop.

This kept going well till the real problem showed up. The plastic 'finger' that pushes the solenoid in was worn out/half broken.

Funny but true. Turning on was okay but for turning off there is more force needed. All 3 of my Panasonic heaters had the same problem.

Panasonics are a bit old, so plastic must have been degraded.

So, not saying it's the same at OP's end, but maybe worth checking if the switch is not obstructed

I have the same problem with my Panasonic heater (about 8-10 years old now, so doing quite well really).

I usually need to turn it on then off again for it to stop, or very occasionally cycle it many more times...

I suspect it's some dirt that's got through the inlet filter that's causing it to stick, but i'm not going to open it to check in case it fails totally.

In the worst case, just put a hand valve on the inlet supply.. as soon as the water flow stops the heater will cut out (or should do).  

your valve is not closing instantly

thanks Steve, it is not mine so will just put up with it until it packs up and then complain.

Yes, I had to do that 5 times in the end. Also Panasonics of that age.

But it is easy to check if it is the handle or the valve/solenoid.

Unplug mains, open hood with just one screw and see what is happening mechanically between the valve and the on/off handle.

Try to lock and unlock the valve with a screw driver as well to see if it is the valve itself. It's a click on - click off system so works without mains.

My electric shower in the UK does this.

All sorted, wish admin could close this.
