We did not have as good of luck with PHD as the other reviewer. They installed a new sink in our 5th wheel RV. It was an insurance claim and they claimed they did a lot of insurance claims. It took them forever to get the settlement — we had to intercede on their behalf — come to find out they never submitted the invoice for payment and couldn’t understand why they had not gotten paid. That was the least of the problems — we got 6 days out of Yuma and all the connections under the sink let go — they had cut all the PVC sections too short and had many pieces when one would have done fine if cut correctly. We had a mess and it cost us almost $ 400 to get it fixed on the road. They had also told us they did a lot of work in RV’s. Mike Miller(the owner) would not give us any satisfaction even though the parts and labor were guaranteed for one year. Since we no longer were in Yuma we were out of luck. Not good customer service, look elsewhere if you want a reputable firm.
