Hi, have managed to solve the problem, which after swapping thermostatic cartridges, removing NRV's and . trying a new replacement pump turns out to be a simple issue of the taps on the bath. The bath is connected via a simple a tee off from the pipes feeding the new Crosswater showershower...

Thanks, will try to get installer back, though he is not responsive hence trying to sort out myself. Guess I could sue him, but would rather just sort it.

Replaced monsoon pump with new one with no effect, so that rules out the pump. Already replaced the CW cartridge so rules out that. Aqualisa works normally (with lower pressure) when pump turned off, but tepid with pump turned on. Crosswater produces tepid water with pump turned on or off, and...

Hi John, the shower pumps are fed from a tank in the loft which is in turn fed from mains. The install has been running fine for years on the setup which is cold from tanks, hot from cylinder, 22mm pipe works etc. The only recent change was a refurb on the main bathroom and install of new...

Terry, thanks for your persistent help. I did initially try moving the hot NRV only but had no effect. Based upon your assessment I agree it may be something to do with the pump. I would have swapped the pumps over but as all gate valves are sized up, I was using the isolator valve on the pump...

The pressure was good. I removed the non return valves from the shower earlier on advice from Crosswater so the hot would not be closed but could be overpowered as you describe. There are no flexible pipes, valves or connectors in between the shower pump and the showers, though the extension on...

Thanks, seems to run hot, though not on long enough to get to full hot temp.

Did as instructed and get a weak flow of hot water on both showers!

Cylinder is Hercal 245l 1500cm, covered in thick blue/green insulation layer. All other hot water supplies in the house are ok, including two other thermostatic showers (one Crosswater and one Aqualisa -exactly the same a problem two.) the good showers are fed off a separate monsoon pump.

The Aqualisa is old, though not frequently used, it has however never had a problem before, it display exactly the same characteristics as the Crosswater in that goes to tepid but up if you switch to max cold then max hot it will flow hot water for a few seconds before then reverting to tepid...

From a thermometer the actual temp is 58 Deg C

Ok, will need to measure with thermometer

Thank you for the reply. The hot water temp is set to 60 Deg C, which should be within the operating temp for the pump and the cartridge.

hi, I have a recently installed Crosswater MikePro 1500C Thermostatic shower running off of a Monsoon 3Bar standard booster twin pump. The Crosswater shower was running ok for a couple of months however has recently started to run tepid even if the temp setting is set to the maximum. If I...
